Sonoff with HA without soldering by OTA - Wifi using SonOTA

Which firmware you HAD before?

All my Sonoff POW have 2.02 or 2.04 firmware version, and on the SonOTA is written do not try it if firmware above 1.6 … ?

I don’t know how to get my pow2 version but I ended up with this https://i.imgur.com/5fiHNNh.png :slight_smile: Any help?

you may have to flash it wired… I think sonota is discontinued

It seems that flashing over the air is not possible for all firmware versions.
