homebridge-mqtt-power-consumption-log-tasmota

Plugin to HomeBridge optimized for work with Itead Sonoff POW hardware with firmware Sonoff-Tasmota via MQTT with log data to file. Partially emulate Elgato Eve Energy. Measure used power and write logged data to csv files. It acts as a power switch and meter energy consumed.

Like this? Please buy me a beer (or coffee) ;-)
