I am just trying to start with Home Assistant using a few Sonoff S31 plugs. Running HAOS (2024.12.1) on a VM on a qnap. I have been able to wire the TTL converter and flash ESPHome to the units. I then unplug the TTL and plug back in as advised on various tutorials.
When wired, Home Assistant can find the plugs and I can access the s31’s web server and logs. After putting the unit back together and plugging it into the wall, it does not connect to the wifi, no HA response, logs, nothing. I wire it back up to the TTL, plug it back into my computer and it is back again. This is repeatable on all of the (same) switches I bought. What am I missing?

I wanted to mention that the s31 connects to wifi when plugged into the wall. I am also able to navigate to a very simple wifi selection page using both the ip and plug_02.local (mdns). I believe this is supposed to be a esphome page. The page also has a section to upload an OTA update, which fails saying “Update Failed: ERROR[4]: Not Enough Space”.

Highly probably this is Access Point page which starts when device can’t connect to configured WiFi.
Did You tried to select right WiFi and enyter password ? Is it connects ?
YAML file looks fine IMHO.
Yes, you are correct. It is the initial wifi access page. Strange thing, even when it is connected to the existing network, it is still broadcasting the fallback. Both showing the same access page.
AFAIK then must not happens. OR it connects to WiFi and show web_server specified frontend OR it not connects to WiFi, then starts fallback AP. Not both same time.
