Getting it up and running

Tuya Convert

These wall plugs are Tuya devices, and you can compile the below code in ESPHome, "manually install" to get the .bin file, then use tuya-convert to initially get ESPHome onto the device. After that, you can use ESPHome's OTA functionality to make any further changes.

• Put the switch into "smartconfig" / "autoconfig" / pairing mode by holding the button for about 5 seconds until it clicks

• The status LED blinks rapidly to confirm that it has entered pairing mode.

• Be patient with tuya-convert, and you may need to try a few times to get tuya-convert to connect to the device
