Hello!
Not exactly HA question, but I have a bit weird issue: I flashed a Sonoff Basic R3 and a 4CH R3 with ESPhome and both devices show now no sign of life anymore, no flashing LEDs of anything, when I connect to the mains. Any ideas what I can do now (apart from throwing them away and getting new one…)?
I used ESPHome and followed the standard code generated on the dashboard. I then flashed using a FTDI serial adapter, by putting the jumpercables as described in the guide into the board. I had tripled checked the cabling and from all messaging on the console it seemed to have worked. In both cases it showed the expected messages and then nothing. I then connected to the mains and no LEDs came on on either of them.
I followed this post and states one should first install the config without the switches etc. So I did that and according to the description the device should start flashing once connected to the mains but it does nothing. No LED no nothing! I will try tomorrow the suggestion, if I can somehow read logs or so.
Yep did a few last week and they show no LEDS till you flash the code in the page linked above. In the ESPhome window your sonoff should show up and say online in the top right corner. If it does its working. then just flash the full code and away you go.
you need api: and/or logger: included for HA to pick it up.
If you did not have captive_portal: included, then flash it again with that line included among with the two above.
Keep the flasher device on it and set up a serial connection to it to get its output when it starts up after the flashing.
