I see…
so here I end …
I’m going back to the forest …
Thank you for your precious time …
I will try to get back the original firmware for the basic R3 or buy a new one
Can’t you just make the changes in ESPHome and re-upload the Firmware?
You can also manually upload your firmware to the Sonoff with a USB cable. For example a FT232 they are about £/€ 4 - 8 off ebay
