Yes, I have just done it. I was on Tasmota v12.3.1
I was scared that I will end up with similar situation as you’ve had so I have tried to downgrade first to v11.1 but this failed due to insufficient disk space.
I have done the following:
- Tasmota console: SetOption78 1
- Build as small ESPHome bin as possible (just a single basic
switch.gpio). This resulted in quite big file 498kB - I have gzipped it with 7-zip and the result file was 345kB (I thought it will fail to upload as well but it didn’t!)
Looks like it worked. I was able to control the relay in my socket via exposed switch entity and I have successfully upladed new updates over the WiFi.
I hope you will fix your device somehow. Good luck!
