ABB Aurora (ESPHOME)

This is an ESPHome component for the ABB Aurora SOLAR inverter. It is connected via RS485 to an ESP8266 (Wemos D1 mini).

The code is based on https://github.com/jrbenito/ABBAurora that again was based on the work of Davide Rosa https://www.drhack.it/arduino/32-lettura-inverte-power-one-aurora.html

The original work was made available under the LGPL v2.1 license. I published the modified library (component) under GPL v3.
