![[ZIGBEE] 20A Zigbee socket with energy metering (Tuya TS011F_plug_3)](https://obrazki.elektroda.pl/1000454900_1749493372_thumb.jpg)
This is a 10A smart breaker that I got off AliExpress. It has an ESP8285 chip inside for which the GUI flashing tool didnt work, nor did cloudcutter. Software I believe was 1.1.8 but I have no way to check anymore and I forgot to write it down!
To flash the chip, I desoldered it from the pcb and connected rx, tx, 3.3v, gnd and gpio pins to a usb-uart ttl converter. I tried flashing without desoldering but think the capacitors messed up the timings..
I flashed the chip with EspHome using the EspHome wizard (see https://esphome.io/guides/getting_started_command_line.html) and extensive esphome docs to guide me. Finally, I flashed the following config.yaml after some trial and error to get the relay, button and wifi-led set up:
