After flashing an ESPHome update on my Shelly Plug S, it does not connect anymore to the wifi nor does it start its own access point. I will have to flash it by serial.
How do I access the board on this device?
There should be a screw hiden inside the earth plug.
got the pinout from this post
Flashing can be anoying, you could solder it but I just pushed some breadboard wires in the holes and applied sideways pressure while flashing to ensure proper contact.
