feat(v2.0): Auto-discovery, correzione bug critici, e documentazione completa
Build Docker Image for Raspberry Pi / build-and-push (push) Failing after 4m42s
Details

Browse Source 
🆕 Funzionalità Auto-Discovery
- Aggiunto metodo AutoDiscoverBufferSizes() per rilevamento automatico QPIGS/QPIRI/QMOD/QPIWS
- Supporto variabili d'ambiente (INVERTER_DEVICE, MQTT_SERVER, etc.)
- Caching persistente buffer sizes in /cache/inverter.conf.cache
- Flag -a/--auto-discover per modalità auto-detection

🐛 Bug Fixes Critici
- **Parsing interi**: Aggiunta attemptAddSettingInt() con stoi() invece di stof()
  - Fix: stof('98') = 98.0f → 97 (int), ora stoi('98') = 98 direttamente
  - Applicato a: qpiri, qpiws, qmod, qpigs
- **Thread sync**: Aggiunto ups_qpiws_changed a main loop e condizione exit poll()
  - Fix: loop principale controllava solo 3 flag su 4, causava hang
  - Fix: thread poll() non usciva in runOnce perché mancava controllo QPIWS
- **Config accuracy**: Corretti buffer sizes (qpiri: 98→103, qpiws: 36→40)
  - Rimosso sources/inverter-cli/inverter.conf che sovrascriveva config globale
  - Validato con test: inverter_poller -1 completa in 6s con JSON completo

📚 Documentazione Completa
- Creato documentation/CODE_ARCHITECTURE.md (38KB)
  - Mappa logica variabili globali
  - Flusso esecuzione main() con diagrammi ASCII
  - Sequence diagram classe cInverter (poll, query, auto-discovery)
  - Thread synchronization diagrams
  - MQTT integration bash scripts flow
  - Mappa concettuale 5-layer system architecture
  - Error handling e performance optimizations
- Organizzati file .md in documentation/ (AUTO_DISCOVERY, IMPLEMENTATION, QUICKSTART, DEBUG)
- Aggiornato README.md con sezione v2.0 e indice documentazione
- Aggiornato .github/copilot-instructions.md con novità v2.0

🔧 Miglioramenti Build & CI/CD
- Gitea Actions per build multi-arch (arm/v6, arm/v7, arm64, amd64, 386)
- Configurazione VS Code completa (tasks, launch, debug GDB)
- Script test-autodiscovery.sh e test-device.sh

✅ Testing Validato
- inverter_poller -1 completa in 6 secondi
- Output JSON completo con tutte le metriche
- Exit pulito senza timeout (exit code 0)
- Tutte le 4 query QMOD/QPIGS/QPIRI/QPIWS funzionanti

# Gitea Actions per Docker - Raspberry Pi
Questo progetto utilizza Gitea Actions per automatizzare la build e il deployment delle immagini Docker per architetture ARM (Raspberry Pi).
## Workflows Disponibili
### 1. docker-build.yml
Build e push automatico delle immagini Docker multi-architettura per Raspberry Pi.
**Trigger:**
- Push su branch `main`, `master`, o `develop`
- Creazione di tag con pattern `v*` (es. v1.0.0)
- Pull request su `main` o `master`
**Architetture supportate:**
- `linux/arm/v6` - Raspberry Pi Zero, Pi 1
- `linux/arm/v7` - Raspberry Pi 2, 3, 4 (32-bit)
- `linux/arm64` - Raspberry Pi 3, 4 (64-bit)
### 2. docker-test.yml
Test della build Docker senza pubblicazione.
**Trigger:**
- Pull request su branch principali
### 3. docker-cleanup.yml
Pulizia periodica delle immagini Docker vecchie.
**Trigger:**
- Schedulato: ogni domenica alle 2:00 AM
- Manuale: tramite workflow_dispatch
## Configurazione
### Secrets Richiesti
Per utilizzare questi workflows, devi configurare i seguenti secrets in Gitea:
1. **DOCKER_USERNAME**: Il tuo username Docker Hub
2. **DOCKER_PASSWORD**: Il tuo password/token Docker Hub
#### Come aggiungere i secrets in Gitea:
1. Vai nelle impostazioni del repository
2. Seleziona `Secrets` → `Actions`
3. Aggiungi i seguenti secrets:
- Nome: `DOCKER_USERNAME`, Valore: `tuo-username-dockerhub`
- Nome: `DOCKER_PASSWORD`, Valore: `tuo-password-o-token-dockerhub`
### Configurazione Runner Gitea
Assicurati di avere un Gitea Actions runner configurato. Se stai usando un Raspberry Pi come runner:
```bash
# Installa il runner Gitea (act_runner)
wget https://dl.gitea.com/act_runner/latest/act_runner-latest-linux-arm64 -O act_runner
chmod +x act_runner
# Registra il runner
./act_runner register --instance https://tuo-gitea-server.com --token IL_TUO_TOKEN
# Avvia il runner
./act_runner daemon
```
## Tag e Versioning
Le immagini Docker vengono taggate automaticamente:
- `latest` - ultima versione del branch principale
- `main` / `master` / `develop` - nome del branch
- `v1.2.3` - versioni semver dai tag Git
- `1.2` - major.minor dai tag semver
- `pr-123` - numero della pull request
## Build Locale
Per testare la build localmente:
```bash
# Build per Raspberry Pi 4 (64-bit)
docker buildx build --platform linux/arm64 -f Dockerfile.multiarch -t ha-voltronic-mqtt:test .
# Build per Raspberry Pi 3 (32-bit)
docker buildx build --platform linux/arm/v7 -f Dockerfile.multiarch -t ha-voltronic-mqtt:test .
# Build multi-arch (richiede buildx con QEMU)
docker buildx build --platform linux/arm/v6,linux/arm/v7,linux/arm64 \
-f Dockerfile.multiarch -t ha-voltronic-mqtt:test .
```
## Cache
I workflow utilizzano GitHub Actions cache (compatibile con Gitea) per velocizzare le build successive:
- `cache-from: type=gha` - utilizza cache esistente
- `cache-to: type=gha,mode=max` - salva cache completa
## Troubleshooting
### Build fallisce con "platform not supported"
Verifica che il runner abbia QEMU installato e configurato per l'emulazione multi-arch.
### Secrets non trovati
Assicurati di aver configurato correttamente i secrets nelle impostazioni del repository Gitea.
### Runner non esegue i workflow
Verifica che il runner sia attivo e registrato correttamente con il comando:
```bash
./act_runner daemon --log-level debug
```
## Note
- Le build multi-arch possono richiedere diversi minuti, specialmente su hardware limitato
- Per Raspberry Pi si consiglia di usare un server separato per le build, non il Pi stesso
- Il workflow utilizza Docker Buildx per supporto multi-architettura

# GitHub Copilot Instructions - Voltronic/Axpert MQTT Home Assistant Integration
## Panoramica del Progetto
Questo progetto è un'applicazione Docker che monitora inverter solari Voltronic, Axpert, MPPSolar PIP, Voltacon, Effekta e altri inverter OEM basati su protocollo RS232. L'applicazione raccoglie dati telemetrici dall'inverter e li invia a Home Assistant tramite MQTT, permettendo anche di inviare comandi per controllare l'inverter remotamente.
### 🆕 Version 2.0 - Auto-Discovery Feature
La versione 2.0 introduce l'**auto-discovery automatica** dei buffer sizes dell'inverter, eliminando la necessità di configurazione manuale. Al primo avvio, l'applicazione:
1. Rileva automaticamente le dimensioni corrette dei buffer per QPIGS, QPIRI, QMOD, QPIWS
2. Salva i valori in `/cache/inverter.conf.cache`
3. Nei successivi avvii, utilizza i valori cached per startup immediato
**Novità tecniche principali:**
- 🔍 **Auto-detection buffer sizes**: Metodo `AutoDiscoverBufferSizes()` con iterazione 80-120 bytes
- ⚙️ **Configurazione ENV**: Supporto variabili d'ambiente (`INVERTER_DEVICE`, `MQTT_SERVER`, etc.)
- 💾 **Caching persistente**: Volume Docker `/cache/` per persistenza tra restart
- 🐛 **Bug fixes critici**:
- Parsing interi: aggiunta `attemptAddSettingInt()` con `stoi()` invece di `stof()` che troncava valori
- Thread sync: aggiunta `ups_qpiws_changed` al loop principale e condizione exit `poll()`
- Config accuracy: corretti buffer sizes (qpiri=98→103, qpiws=36→40)
📖 **Documentazione completa:** [documentation/CODE_ARCHITECTURE.md](../documentation/CODE_ARCHITECTURE.md)

## Convenzioni di Codice
### C++ (inverter-cli)
- **Standard:** C++11 (`--std=c++0x`)
- **Stile nomi:**
- Classi: `cNomeClasse` (prefisso 'c')
- Metodi: `PascalCase` (es. `GetMode()`, `SetMode()`)
- Variabili locali: `snake_case` (es. `voltage_grid`, `batt_capacity`)
- Variabili globali: `camelCase` (es. `devicename`, `runinterval`)
- Costanti: `UPPER_CASE` (es. `LOG_FILE`)
- **Threading:**
- Usare `std::mutex` per proteggere dati condivisi
- Pattern detached thread per polling: `thread t1(&cInverter::poll, this); t1.detach();`
- Usare `atomic_bool` per flag di stato
- **Logging:**
- Funzione `lprintf()` per debug condizionale
- Scrive su stdout e file di log
- Thread-safe con mutex
- **Error handling:**
- Try-catch per parsing configurazione
- Controllo errno per operazioni file/seriale
- Sleep e retry su errori apertura device
### Bash Scripts
- **Stile:**
- Variabili uppercase per config (es. `MQTT_SERVER`)
- Backtick o `$()` per command substitution
- Controllo valori vuoti: `[ ! -z "$var" ]`
- **Pattern comuni:**
```bash
VAR=`cat /etc/inverter/mqtt.json | jq '.key' -r`
[ ! -z "$VAR" ] && pushMQTTData "metric" "$VAR"
```

- Payload JSON con: name, state_topic, unit_of_measurement, device_class, icon
### Invio Comandi
Pubblica su topic: `homeassistant/sensor/{devicename}/command`
Esempio automation:
```yaml
automation:
- alias: "Switch to Solar Priority Morning"
trigger:
platform: time
at: "06:00:00"
action:
service: mqtt.publish
data:
topic: "homeassistant/sensor/voltronic/command"
payload: "POP01"
```
## Gitea Actions

## ✨ Version 2.0 - Auto-Discovery Feature
Questa versione introduce l'**auto-discovery automatica dei parametri dell'inverter**, eliminando la necessità di configurazione manuale dei buffer sizes. Il container rileva automaticamente i parametri corretti al primo avvio e li salva per utilizzi futuri.
**Novità principali:**
- 🔍 Auto-detection buffer sizes per diversi modelli di inverter
- ⚙️ Configurazione tramite variabili d'ambiente Docker
- 💾 Caching persistente dei parametri scoperti
- 🔄 Multi-inverter support con discovery indipendente
- 🐛 Bug fixes: parsing interi, sincronizzazione thread, gestione QPIWS
📖 **Documentazione completa:** [documentation/](documentation/)

- builds on docker hub are currently for `linux/amd64,linux/arm/v6,linux/arm/v7,linux/arm64,linux/386` -- If you have issues standing up the image on your Linux distribution (i.e. An old Pi/ARM device) you may need to manually build the image to support your local device architecture - This can be done by uncommenting the build flag in your docker-compose.yml file. The container now includes **automatic buffer size detection** for different inverter models. At first startup, it will:
- The default `docker-compose.yml` file includes Watchtower, which can be configured to auto-update this image when we push new changes to github - Please **uncomment if you wish to auto-update to the latest builds of this project**. 1. **Auto-detect** the correct communication parameters for your specific inverter
2. **Save** the discovered settings to `/etc/inverter/.discovery_done`
3. **Reuse** saved settings on subsequent startups (instant start)
## Integrating into Home Assistant. **Environment Variables:**
```yaml
environment:
- INVERTER_DEVICE=/dev/ttyUSB1 # Your RS232/USB device
- FORCE_DISCOVERY=false # Re-run discovery on every start
- SKIP_DISCOVERY=false # Skip discovery, use inverter.conf values
```
Providing you have setup [MQTT](https://www.home-assistant.io/components/mqtt/) with Home Assistant, the device will automatically register in your Home Assistant when the container starts for the first time -- You do not need to manually define any sensors. **📖 See [AUTO_DISCOVERY.md](AUTO_DISCOVERY.md) for complete documentation** including:
- How auto-discovery works
From here you can setup [Graphs](https://www.home-assistant.io/lovelace/history-graph/) to display sensor data, and optionally change state of the inverter by "[publishing](https://www.home-assistant.io/docs/mqtt/service/)" a string to the inverter's primary topic like so: - Environment variable reference
- Multi-inverter setups
- Troubleshooting guide
- Migration from older versions

# Auto-Discovery Feature
Il sistema di auto-discovery rileva automaticamente i parametri di comunicazione corretti del tuo inverter all'avvio del container.
## Come Funziona
All'avvio, il container:
1. **Controlla** se esiste già una configurazione salvata (`.discovery_done`)
2. **Testa** la comunicazione con l'inverter inviando i 4 comandi principali
3. **Rileva** le dimensioni corrette del buffer per ogni comando
4. **Salva** i parametri scoperti in `/etc/inverter/.discovery_done`
5. **Aggiorna** `/etc/inverter/inverter.conf` con i valori corretti
6. **Avvia** i servizi MQTT normalmente
## Variabili d'Ambiente
### `INVERTER_DEVICE`
Specifica il device seriale dell'inverter.
**Default:** `/dev/ttyUSB0`
**Esempi:**
```yaml
environment:
- INVERTER_DEVICE=/dev/ttyUSB1 # USB-to-Serial adapter
- INVERTER_DEVICE=/dev/ttyS0 # Built-in serial port
- INVERTER_DEVICE=/dev/hidraw0 # USB HID device
```
### `FORCE_DISCOVERY`
Forza l'auto-discovery ad ogni avvio, anche se esistono già parametri salvati.
**Default:** `false`
**Quando usarlo:**
- Dopo aver cambiato inverter
- Se sospetti che i parametri salvati siano errati
- Per debug o testing
**Esempio:**
```yaml
environment:
- FORCE_DISCOVERY=true
```
### `SKIP_DISCOVERY`
Salta completamente l'auto-discovery e usa solo i valori da `inverter.conf`.
**Default:** `false`
**Quando usarlo:**
- Quando conosci già i parametri corretti
- Per velocizzare l'avvio (risparmia ~10 secondi)
- In ambienti di produzione stabili
**Esempio:**
```yaml
environment:
- SKIP_DISCOVERY=true
```
## Scenari d'Uso
### Scenario 1: Primo Avvio (Default)
```yaml
services:
voltronic-mqtt:
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
```
**Cosa succede:**
- ✓ Container rileva che non esiste `.discovery_done`
- ✓ Esegue auto-discovery (~10-15 secondi)
- ✓ Salva i parametri trovati
- ✓ Avvia i servizi MQTT
**Log:**
```
=== Voltronic MQTT Bridge Starting ===
Configuration:
Device: /dev/ttyUSB1
Force Discovery: false
Skip Discovery: false
ℹ No previous discovery found, will run auto-discovery
=== Running Auto-Discovery ===
This will take about 10-15 seconds...
Testing QMOD command (buffer 5-100)...
✓ QMOD: found response at 5 bytes
...
✓ Auto-discovery completed successfully!
device=/dev/ttyUSB1
qmod=5
qpigs=110
qpiri=103
qpiws=40
```
### Scenario 2: Avvii Successivi (Cached)
```yaml
services:
voltronic-mqtt:
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
```
**Cosa succede:**
- ✓ Container trova `.discovery_done` esistente
- ✓ Verifica che il device non sia cambiato
- ✓ Carica i parametri salvati
- ✓ Avvia immediatamente i servizi (nessun ritardo)
**Log:**
```
=== Voltronic MQTT Bridge Starting ===
Configuration:
Device: /dev/ttyUSB1
Force Discovery: false
Skip Discovery: false
✓ Using previous discovery results
Current configuration:
device=/dev/ttyUSB1
qmod=5
qpigs=110
qpiri=103
qpiws=40
=== Starting MQTT Bridge Services ===
```
### Scenario 3: Cambio Device
```yaml
services:
voltronic-mqtt:
environment:
- INVERTER_DEVICE=/dev/ttyUSB0 # Cambiato da ttyUSB1
```
**Cosa succede:**
- ✓ Container rileva che il device è cambiato
- ✓ Elimina `.discovery_done` esistente
- ✓ Esegue nuovamente l'auto-discovery
- ✓ Salva i nuovi parametri
**Log:**
```
⚠ Device changed from /dev/ttyUSB1 to /dev/ttyUSB0
Running new discovery...
=== Running Auto-Discovery ===
...
```
### Scenario 4: Force Discovery
```yaml
services:
voltronic-mqtt:
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
- FORCE_DISCOVERY=true
```
**Cosa succede:**
- ✓ Ignora `.discovery_done` esistente
- ✓ Esegue sempre auto-discovery
- ✓ Aggiorna parametri salvati
**Quando usarlo:** Dopo aggiornamento firmware inverter, troubleshooting.
### Scenario 5: Skip Discovery
```yaml
services:
voltronic-mqtt:
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
- SKIP_DISCOVERY=true
```
**Cosa succede:**
- ✓ Non esegue mai auto-discovery
- ✓ Usa solo valori da `config/inverter.conf`
- ✓ Avvio istantaneo
**Quando usarlo:** Parametri già noti e stabili, avvio rapido richiesto.
## File Generati
### `/etc/inverter/.discovery_done`
Contiene i parametri scoperti con timestamp:
```bash
device=/dev/ttyUSB1
qmod=5
qpigs=110
qpiri=103
qpiws=40
timestamp=2024-01-15T10:30:00+01:00
```
Questo file è **persistente** nel volume `./config/` e sopravvive ai restart del container.
### `/etc/inverter/inverter.conf.backup`
Backup automatico della configurazione originale prima dell'auto-discovery.
## Troubleshooting
### Discovery Fallisce
**Log:**
```
✗ Auto-discovery failed!
Please check:
1. Inverter is powered on
2. Cable is properly connected
3. Device path is correct: /dev/ttyUSB1
Falling back to default configuration...
```
**Soluzioni:**
1. Verifica che l'inverter sia acceso
2. Controlla il cablaggio RS232/USB
3. Verifica il device corretto: `ls -la /dev/tty*`
4. Testa manualmente:
```bash
docker exec -it voltronic-mqtt /opt/inverter-cli/bin/inverter_poller -a
```
### Device Non Trovato
**Errore:**
```
Unable to open device file
```
**Soluzioni:**
1. Verifica mapping in docker-compose.yml:
```yaml
devices:
- /dev/ttyUSB1:/dev/ttyUSB1:rwm
```
2. Controlla permessi: `sudo chmod 666 /dev/ttyUSB1`
3. Verifica che il device esista: `ls -la /dev/ttyUSB1`
### Valori Scoperti Errati
**Soluzione 1 - Force Discovery:**
```yaml
environment:
- FORCE_DISCOVERY=true
```
**Soluzione 2 - Configurazione Manuale:**
```yaml
environment:
- SKIP_DISCOVERY=true
```
E modifica manualmente `config/inverter.conf`:
```bash
device=/dev/ttyUSB1
qmod=5
qpigs=110
qpiri=103
qpiws=40
```
## Test Manuale
Puoi testare l'auto-discovery manualmente senza riavviare il container:
```bash
# Test base
docker exec -it voltronic-mqtt /opt/inverter-cli/bin/inverter_poller -a
# Test con debug
docker exec -it voltronic-mqtt /opt/inverter-cli/bin/inverter_poller -d -a
# Test singolo comando
docker exec -it voltronic-mqtt /opt/inverter-cli/bin/inverter_poller -r QPIGS
```
## Best Practices
1. **Primo Setup:** Lascia auto-discovery attivo (default)
2. **Produzione:** Dopo aver verificato che funzioni, considera `SKIP_DISCOVERY=true` per avvio rapido
3. **Multi-Inverter:** Usa container separati con `INVERTER_DEVICE` diversi
4. **Backup:** Salva `config/.discovery_done` dopo il primo successo
5. **Logging:** Monitora i log del primo avvio per verificare discovery:
```bash
docker logs voltronic-mqtt
```
## Esempio Completo docker-compose.yml
```yaml
version: '3'
services:
# Inverter primario su ttyUSB1
voltronic-mqtt-primary:
image: bushrangers/ha-voltronic-mqtt
container_name: voltronic-mqtt-primary
privileged: true
restart: always
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
- FORCE_DISCOVERY=false
- SKIP_DISCOVERY=false
volumes:
- ./config-primary/:/etc/inverter/
devices:
- /dev/ttyUSB1:/dev/ttyUSB1:rwm
# Inverter secondario su ttyUSB0 (discovery skippato)
voltronic-mqtt-secondary:
image: bushrangers/ha-voltronic-mqtt
container_name: voltronic-mqtt-secondary
privileged: true
restart: always
environment:
- INVERTER_DEVICE=/dev/ttyUSB0
- SKIP_DISCOVERY=true # Parametri già noti
volumes:
- ./config-secondary/:/etc/inverter/
devices:
- /dev/ttyUSB0:/dev/ttyUSB0:rwm
```
## Migrazione da Versione Precedente
Se stai aggiornando da una versione senza auto-discovery:
1. **Backup configurazione esistente:**
```bash
cp config/inverter.conf config/inverter.conf.old
```
2. **Aggiungi variabili d'ambiente al docker-compose.yml:**
```yaml
environment:
- INVERTER_DEVICE=/dev/ttyUSB1 # Il tuo device attuale
```
3. **Primo avvio con auto-discovery:**
```bash
docker-compose down
docker-compose up -d
docker logs -f voltronic-mqtt
```
4. **Verifica risultati:**
```bash
cat config/.discovery_done
```
5. **Se tutto OK, abilita skip per avvio rapido:**
```yaml
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
- SKIP_DISCOVERY=true # Usa parametri scoperti
```
## FAQ
**Q: Quanto tempo impiega l'auto-discovery?**
A: Circa 10-15 secondi al primo avvio. Gli avvii successivi sono istantanei.
**Q: Posso usare auto-discovery con più inverter?**
A: Sì! Usa container separati con `INVERTER_DEVICE` diversi e directory config separate.
**Q: Cosa succede se l'inverter è spento durante discovery?**
A: Il container fallisce gracefully e usa i parametri di default da `inverter.conf`.
**Q: Devo eliminare `.discovery_done` manualmente?**
A: No, il container lo fa automaticamente quando cambi `INVERTER_DEVICE` o usi `FORCE_DISCOVERY=true`.
**Q: Posso disabilitare completamente auto-discovery?**
A: Sì, usa `SKIP_DISCOVERY=true`.
**Q: I parametri scoperti sono persistenti?**
A: Sì, sono salvati nel volume `./config/` e sopravvivono ai restart.

# Architettura del Codice - Mappa Logica e Flusso di Esecuzione
## Panoramica Generale
Il progetto è composto da due componenti principali:
1. **inverter-cli** (C++): Applicazione che comunica con l'inverter via RS232/USB
2. **inverter-mqtt** (Bash): Script che gestiscono l'integrazione MQTT con Home Assistant

string devicename = "/dev/ttyUSB0"; // Device seriale
float runinterval = 0; // Intervallo polling (120 = ogni 30s)
float ampfactor = 1; // Fattore correzione amperaggio
float wattfactor = 1; // Fattore correzione wattaggio
int qpiri = 0, qpiws = 0; // Buffer sizes comandi
int qmod = 0, qpigs = 0;
// Flag di controllo
bool debugFlag = false; // Debug mode
bool runOnce = false; // Esegui una volta e esci
// Flag atomici per sincronizzazione thread
atomic_bool ups_status_changed(false);
atomic_bool ups_qmod_changed(false); // Mode query completata
atomic_bool ups_qpiri_changed(false); // QPIRI query completata

│
└─> Formato risposta errato
├─> Log hex dump (se debug)

```
### Auto-Recovery Container
```

├─> 120 = ogni 30 secondi (default)
├─> 60 = ogni minuto
└─> 30 = ogni 2 minuti
Thread poll interno:
├─> Query sequenziali (non parallele)
├─> Sleep 2s tra cicli
└─> Immediate exit se runOnce mode
```
### Buffer Management
```
Buffer sizes ottimizzati per ogni comando:
├─> QMOD: 5 bytes (fisso)
├─> QPIGS: 110 bytes (varia per modello)
├─> QPIRI: 103 bytes (varia per modello)
└─> QPIWS: 40 bytes (varia per modello)
Auto-discovery determina sizes esatti:
└─> Evita letture incomplete o overhead
```
### Caching MQTT
```
entrypoint.sh:
├─> .discovery_done persiste parametri
├─> Evita re-discovery ad ogni restart
└─> Re-discovery solo se:
├─> FORCE_DISCOVERY=true
├─> Device cambiato
└─> File cache non esiste
```
---
## Debugging e Logging
### Livelli di Debug
```
inverter_poller -d:
├─> Abilita lprintf() output
├─> Stampa parametri configurazione
├─> Hex dump buffer seriali
├─> Log apertura/chiusura device
└─> Timestamps su ogni operazione
entrypoint.sh:
├─> Echo ogni step esecuzione
├─> Simboli visual: ✓ ✗ ⚠ ℹ
└─> Log risultati discovery
mqtt-push.sh:
└─> Silenzioso (output su /dev/null)
```
### File di Log
```
/var/log/inverter.log:
└─> lprintf() scrive qui (se debugFlag=true)
Container logs:
└─> docker logs voltronic-mqtt
├─> Output entrypoint.sh
├─> Errori servizi MQTT
└─> Messaggi discovery
```

Questa directory contiene le configurazioni per il debug dell'applicazione `inverter-cli` in VS Code.
## Prerequisiti
### Software Richiesto
```bash
# Installa gli strumenti di build e debug
sudo apt-get update
sudo apt-get install -y build-essential cmake gdb
# Verifica installazione
gdb --version
cmake --version
g++ --version
```
### Estensioni VS Code Consigliate
- **C/C++** (ms-vscode.cpptools) - IntelliSense, debugging, browsing
- **CMake** (twxs.cmake) - Syntax highlighting per CMakeLists.txt
- **CMake Tools** (ms-vscode.cmake-tools) - Integrazione CMake avanzata
## Configurazioni di Debug Disponibili
### 1. Debug inverter_poller (Release Build)
**Nome:** `(gdb) Debug inverter_poller`
- Build in modalità Release con ottimizzazioni
- Esegue con flag `-d -1` (debug + run-once)
- Utile per debug rapido senza simboli completi
### 2. Debug inverter_poller - Run Once with Debug
**Nome:** `(gdb) Debug inverter_poller - Run Once with Debug`
- Build in modalità Debug con simboli completi
- Esegue con flag `-d -1`
- Include tutti i simboli di debug per analisi dettagliata
- **Consigliato per debug approfondito**
### 3. Debug inverter_poller - Loop Mode
**Nome:** `(gdb) Debug inverter_poller - Loop Mode`
- Build in modalità Debug
- Esegue in modalità loop continuo con debug `-d`
- Utile per debug di problemi intermittenti o di threading
### 4. Debug inverter_poller - Raw Command
**Nome:** `(gdb) Debug inverter_poller - Raw Command`
- Build in modalità Debug
- Esegue comando raw specifico: `-r QPIGS`
- Modifica l'argomento in launch.json per testare altri comandi
### 5. Attach to running inverter_poller
**Nome:** `(gdb) Attach to running inverter_poller`
- Attach a processo già in esecuzione
- Utile per debug di container o processi daemon
- Richiede permessi adeguati (potrebbe richiedere sudo)
## Tasks di Build
### Build Tasks
#### build-inverter-cli (Default)
```bash
Ctrl+Shift+B
```
Build in modalità Release con ottimizzazioni (-O2).
#### build-inverter-cli-debug
Build in modalità Debug con simboli completi (-O0 -g).
#### clean-inverter-cli
Pulisce tutti i file di build generati.
#### rebuild-inverter-cli
Pulisce e ricompila completamente il progetto.
### Run Tasks
#### run-inverter-cli-once
```bash
Tasks: Run Task → run-inverter-cli-once
```
Compila ed esegue il poller una volta con debug abilitato.
#### run-inverter-cli-loop
Compila ed esegue il poller in modalità loop continuo.
### Docker Tasks
#### docker-build
Build dell'immagine Docker locale per development.
#### docker-run
Avvia il container con docker-compose.
#### docker-logs
Mostra i log del container in tempo reale.
#### docker-stop
Ferma il container docker-compose.
## Workflow di Debug Tipici
### Debug Locale (senza device fisico)
Il programma proverà ad aprire il device seriale. Se non è disponibile, otterrai errori ma puoi comunque:
1. **Debug della logica di parsing:**
```bash
# Modifica temporaneamente main.cpp per usare dati mock
# Oppure esegui con un device virtuale
```
2. **Debug con socat (porta seriale virtuale):**
```bash
# Installa socat
sudo apt-get install socat
# Crea coppia di porte virtuali
socat -d -d pty,raw,echo=0 pty,raw,echo=0
# Output: PTY is /dev/pts/2 e /dev/pts/3
# Modifica config/inverter.conf
device=/dev/pts/2
# In un altro terminale, simula risposte inverter su /dev/pts/3
```
### Debug con Device Reale
1. **Identifica il device:**
```bash
ls -la /dev/ttyUSB* /dev/ttyS* /dev/hidraw*
dmesg | grep tty # Per vedere device USB
```
2. **Verifica permessi:**
```bash
sudo chmod 666 /dev/ttyUSB0 # O il tuo device
# OPPURE aggiungi utente al gruppo
sudo usermod -a -G dialout $USER
# Logout e login necessari
```
3. **Aggiorna configurazione:**
```bash
# Modifica config/inverter.conf
device=/dev/ttyUSB0
```
4. **Avvia debug:**
- Imposta breakpoint dove necessario
- Premi F5 o seleziona configurazione dal menu Debug
- Step through con F10 (step over), F11 (step into)
### Debug Problemi Comuni
#### CRC Errors
**Breakpoint:** `inverter.cpp` → funzione `CheckCRC()`
- Verifica calcolo CRC
- Controlla dati ricevuti in `buf[]`
#### Device Communication Issues
**Breakpoint:** `inverter.cpp` → funzione `query()`
- Verifica apertura device (errno)
- Controlla configurazione seriale (baud rate, etc.)
- Monitora `write()` e `read()` operations
#### Threading Issues
**Breakpoint:** `inverter.cpp` → `poll()` e `main.cpp` → main loop
- Verifica sincronizzazione mutex
- Controlla `atomic_bool` flags
- Watch variables: `ups_status_changed`, ecc.
#### JSON Parsing Issues
**Breakpoint:** `main.cpp` → dopo `sscanf()` calls
- Verifica parsing corretto delle risposte
- Controlla valori delle variabili dopo sscanf
- Debug calcoli (ampfactor, wattfactor)
## Debugging con Watchpoints
### Variabili Chiave da Monitorare
In VS Code Debug View → Watch, aggiungi:
```
voltage_grid
voltage_batt
pv_input_watts
mode
ups_qpigs_changed
device_status
```
### GDB Commands Utili
Nel Debug Console (Ctrl+Shift+Y):
```gdb
# Print strutture dati
-exec p voltage_grid
-exec p device_status
# Backtrace
-exec bt
# Info threads
-exec info threads
# Print tutti i local vars
-exec info locals
# Watch memory
-exec x/100c buf
```
## Configurazione IntelliSense
Il file `.vscode/c_cpp_properties.json` viene auto-generato. Se necessario, puoi personalizzarlo:
```json
{
"configurations": [
{
"name": "Linux",
"includePath": [
"${workspaceFolder}/**",
"/usr/include"
],
"defines": [],
"compilerPath": "/usr/bin/g++",
"cStandard": "c11",
"cppStandard": "c++11",
"intelliSenseMode": "linux-gcc-arm"
}
],
"version": 4
}
```
## Debug Container Docker
### Attach a Container in Esecuzione
```bash
# Trova il processo nel container
docker exec -it voltronic-mqtt ps aux | grep inverter
# Installa gdbserver nel container (se necessario)
docker exec -it voltronic-mqtt apt-get install -y gdbserver
# Avvia gdbserver nel container
docker exec -it voltronic-mqtt gdbserver :2345 /opt/inverter-cli/bin/inverter_poller -d -1
# Nella configurazione launch.json, aggiungi:
{
"name": "(gdb) Remote Debug",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/sources/inverter-cli/bin/inverter_poller",
"miDebuggerServerAddress": "localhost:2345",
"miDebuggerPath": "/usr/bin/gdb",
"MIMode": "gdb"
}
```
### Debug Logs
```bash
# Tail logs in tempo reale
docker logs -f voltronic-mqtt
# Exec nel container per debug manuale
docker exec -it voltronic-mqtt bash
cd /opt/inverter-cli/bin
./inverter_poller -d -1
```
## Performance Profiling
### Con valgrind
```bash
# Installa valgrind
sudo apt-get install valgrind
# Memory leak detection
valgrind --leak-check=full --show-leak-kinds=all \
./sources/inverter-cli/bin/inverter_poller -1
# Profiling
valgrind --tool=callgrind ./sources/inverter-cli/bin/inverter_poller -1
```
### Con gprof
```bash
# Compila con profiling
cd sources/inverter-cli
cmake -DCMAKE_CXX_FLAGS="-pg" .
make
# Esegui
./bin/inverter_poller -1
# Analizza
gprof bin/inverter_poller gmon.out > analysis.txt
```
## Tips & Tricks
1. **Conditional Breakpoints:**
- Click destro su breakpoint → Edit Breakpoint
- Aggiungi condizione, es: `voltage_batt < 24.0`
2. **Logpoints:**
- Invece di breakpoint, logpoint stampa senza fermare
- Click destro → Add Logpoint
- Esempio: `Voltage: {voltage_grid}V`
3. **Debug con file di log:**
- Il programma scrive su `/tmp/inverter.log` (vedi LOG_FILE in tools.h)
- Usa `tail -f /tmp/inverter.log` in terminale separato
4. **Quick Debug:**
```bash
# Build e run rapido senza VS Code
cd sources/inverter-cli
cmake -DCMAKE_BUILD_TYPE=Debug . && make && gdb --args bin/inverter_poller -d -1
```
## Troubleshooting Debug Setup
### GDB non trova simboli
```bash
# Verifica che binary abbia simboli debug
file sources/inverter-cli/bin/inverter_poller
# Output dovrebbe contenere: "not stripped"
# Se stripped, rebuilda in debug mode
cd sources/inverter-cli && cmake -DCMAKE_BUILD_TYPE=Debug . && make
```
### Permission denied su /dev/ttyUSB0
```bash
sudo chmod 666 /dev/ttyUSB0
# O permanentemente:
sudo usermod -a -G dialout $USER
```
### VS Code non trova GDB
```bash
# Installa gdb
sudo apt-get install gdb
# Verifica path in launch.json
which gdb # Usa questo path in miDebuggerPath
```

# 🎉 Auto-Discovery Implementation Complete!
## ✅ What's Been Added
### 1. Auto-Discovery Feature in C++ Binary
**File:** [sources/inverter-cli/inverter.cpp](sources/inverter-cli/inverter.cpp)
- New method `query_auto()` - Reads serial data until CR terminator, auto-detects buffer size
- New method `AutoDiscoverBufferSizes()` - Tests all 4 commands (QMOD, QPIGS, QPIRI, QPIWS)
- Machine-readable output format:
```
DISCOVERY_QMOD=5
DISCOVERY_QPIGS=110
DISCOVERY_QPIRI=103
DISCOVERY_QPIWS=40
DISCOVERY_SUCCESS=true
```
**CLI Flag:** `-a` or `--auto-discover`
```bash
./inverter_poller -a # Run auto-discovery
./inverter_poller -d -a # Run with debug output
```
### 2. Smart Container Entrypoint
**File:** [sources/inverter-mqtt/entrypoint.sh](sources/inverter-mqtt/entrypoint.sh)

## 🔧 Advanced Usage
### Scenario 1: Multiple Inverters
```yaml
services:
inverter-1:
image: bushrangers/ha-voltronic-mqtt
environment:
- INVERTER_DEVICE=/dev/ttyUSB0
volumes:
- ./config-inverter1/:/etc/inverter/
devices:
- /dev/ttyUSB0:/dev/ttyUSB0:rwm
inverter-2:
image: bushrangers/ha-voltronic-mqtt
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
volumes:
- ./config-inverter2/:/etc/inverter/
devices:
- /dev/ttyUSB1:/dev/ttyUSB1:rwm
```
### Scenario 2: Force Re-Discovery
```bash
# Temporary (until restart)
docker exec voltronic-mqtt rm /etc/inverter/.discovery_done
docker restart voltronic-mqtt
# Permanent
docker-compose down
# Edit docker-compose.yml: FORCE_DISCOVERY=true
docker-compose up -d
```
### Scenario 3: Skip Discovery (Production)
```yaml
environment:
- INVERTER_DEVICE=/dev/ttyUSB1
- SKIP_DISCOVERY=true # Use values from inverter.conf
```
---
## 🐛 Troubleshooting
### Discovery Fails
**Symptoms:**
```
✗ Auto-discovery failed!
Falling back to default configuration...
```
**Solutions:**
1. Check inverter is powered on
2. Verify cable connection
3. Test device manually:
```bash
ls -la /dev/ttyUSB*
docker exec voltronic-mqtt /opt/inverter-cli/bin/inverter_poller -r QPIGS
```
### Wrong Device
**Symptoms:**
```
Unable to open device file
```
**Solution:**
```yaml
# Check available devices on host
ls -la /dev/tty*
# Update docker-compose.yml
environment:
- INVERTER_DEVICE=/dev/ttyUSB0 # Change to correct device
# Ensure device is mapped
devices:
- /dev/ttyUSB0:/dev/ttyUSB0:rwm
```
### Discovery Takes Too Long
**Normal:** ~10-15 seconds
**If > 30 seconds:** Check for interference, try different USB port

6. Aggiorna sources/inverter-mqtt/mqtt-push.sh per pushare nuovo valore
7. Aggiorna sources/inverter-mqtt/mqtt-init.sh per auto-discovery
```
### Scenario 4: Debug con Device Reale
```bash
1. Connetti inverter via USB/RS232
2. Identifica device:
ls -la /dev/ttyUSB* # o ttyS*, hidraw*
3. Configura device:
# Modifica config/inverter.conf
device=/dev/ttyUSB0
4. Verifica permessi:
sudo chmod 666 /dev/ttyUSB0
5. Debug normale:
F5 → Seleziona configurazione debug
6. Imposta breakpoint in inverter.cpp → query()
7. Osserva comunicazione seriale in tempo reale
```
### Scenario 5: Test Docker Locale
```bash
# Opzione A: Da VS Code Tasks
1. Tasks → "docker-build"
2. Tasks → "docker-run"
3. Tasks → "docker-logs" (monitora output)
4. Quando finito: Tasks → "docker-stop"
# Opzione B: Da terminale
cd /home/pi/Progetti
docker-compose up --build
# Test manuale nel container
docker exec -it voltronic-mqtt bash
/opt/inverter-cli/bin/inverter_poller -d -1
```
## Comandi Utili
### Build e Run
```bash
# Build Release
cd sources/inverter-cli && cmake . && make
# Build Debug (con simboli)
cd sources/inverter-cli && cmake -DCMAKE_BUILD_TYPE=Debug . && make
# Clean build
cd sources/inverter-cli && rm -rf bin CMakeFiles CMakeCache.txt cmake_install.cmake Makefile
# Run con debug flag
./sources/inverter-cli/bin/inverter_poller -d -1
# Run comando raw
./sources/inverter-cli/bin/inverter_poller -r QPIGS
# Run in loop
./sources/inverter-cli/bin/inverter_poller -d
```
### Test Device
```bash
# Verifica device disponibili
ls -la /dev/tty* /dev/hidraw*
# Test read da device (richiede screen o minicom)
sudo apt-get install screen
sudo screen /dev/ttyUSB0 2400
# Verifica permessi
sudo chmod 666 /dev/ttyUSB0
# O permanente:
sudo usermod -a -G dialout $USER && newgrp dialout
```
### Debug GDB Manuale
```bash
# Build con debug symbols
cd sources/inverter-cli
cmake -DCMAKE_BUILD_TYPE=Debug . && make
# Avvia in GDB
gdb --args bin/inverter_poller -d -1
# Comandi GDB utili:
(gdb) break main.cpp:150 # Breakpoint a linea
(gdb) break cInverter::query # Breakpoint a funzione
(gdb) run # Avvia
(gdb) next # Step over (n)
(gdb) step # Step into (s)
(gdb) continue # Continua (c)
(gdb) print voltage_grid # Stampa variabile (p)
(gdb) info locals # Mostra tutte variabili locali
(gdb) backtrace # Stack trace (bt)
(gdb) quit # Esci (q)
```
### Docker
```bash
# Build locale
docker build -f Dockerfile.dev -t voltronic-mqtt:dev .
# Run
docker-compose up -d
# Logs
docker logs -f voltronic-mqtt
# Exec nel container
docker exec -it voltronic-mqtt bash
# Debug nel container
docker exec -it voltronic-mqtt /opt/inverter-cli/bin/inverter_poller -d -1
# Stop
docker-compose down
```
### Git Workflow
```bash
# Prima di modifiche
git checkout -b feature/nuova-funzionalita
# Durante sviluppo
git add sources/inverter-cli/main.cpp
git commit -m "Add: nuova metrica XYZ"
# Push
git push origin feature/nuova-funzionalita
# Gitea Actions builderà automaticamente su push
```
