As I found no real instructions on flashing the Shelly Plus 1 (not PM) with esphome I decided to write a small guide for everyone also being lost. First of all i got these shellys just for visual reference: There is unfortunately not OTA- flashing method (as of now:17.11.22) so dont just pop them into the wall for now. What you need to flash: Shelly Plus 1 (obvioulsy) USB to UART Adapter (just google it ther are really cheap. I’ve got the CP2102 but others with 3,3V should work as well. D
