I have had a lot of success using esphome.io for various sensors around my house, I was wondering if anyone had tried to use it with the OEM relay?
Also I was wondering if there was any reason why I shouldn’t try this, or if anyone expects me to be unable to flash the stock firmware back on the device afterwards?
Thanks
Just wanted to say that I was able to flash esphome to the device (it was pretty easy to figure out the pins), and am now very happy using esphome on it.
I have setup the esphome config so that it uses the temperature from home assistant unless hass disconnects from the device, you can see my config here: esphome configuration for my Open Energy Monitor thermostat · GitHub
