Just a quick (and maybe stupid) question: would it be somehow possible to use an arduino UNO/Mega with network device with ESPHome? I have a few spots where I don’t have a wifi coverage and therefore would like to use LAN instead of Wifi. It would be nice to make some use of remaining UNOs (+LAN) and the integration of ESPHome in HA is really great.
Don’t really know if ESPHome requires an ESP8266/ESP32 or will also work with an ATMega.
Yup. Seeing it listed under Misc Components now. So with the correct Ethernet module (and making sure esp32 is used and not 8266), this should also be a solution.
I’ve not had occasion to try one yet (so can’t say if they work specifically with ESPHome), but you can get ESP32-POE board with built in Ethernet and can be powered over POE as a bonus!
