# A Docker based Home Assistant interface for Voltronic Solar Inverters # A Docker based Home Assistant interface for MPP/Voltronic Solar Inverters
This project [was derived](https://github.com/leithhobson/skymax-demo-Original) from the 'skymax' [C based monitoring application](https://skyboo.net/2017/03/monitoring-voltronic-power-axpert-mex-inverter-under-linux/) designed to take the monitoring data from Voltronic, Axpert, Mppsolar PIP, Voltacon, Effekta, and other branded OEM Inverters and send it to a Home Assistant MQTT server for ingestion...
