Hi all! I already have a raspy 3 with domoticz and 2 kmtronic relay 8 switch board and 3 xiaomi yeelight.. I'm trying to create a smart home and now I need support for the cheap sonoff devices
Welcome! You will find enough info here to get the Sonoff working with ESPEasy.
Loading the software is simple: first time with a wired connection, once you have ESPEasy installed a new release can be installed via WiFi.
