ELV/EQ3 ETH components to MQTT Bridge
Runs on a Wemos D1 mini/ESP8266, and uses an RFM69HCW module to capture packages from ELV ETH 200 comfort "window sensors" and "remote controls" and publishes them via MQTT. It also subscribes to MQTT topics to control thermostat devices by simulating one "remote control" per thermostat.
It also includes firmware OTA updates either checked at every boot or triggered via MQTT.
