Getting it up and running
Tuya Convert
These switches are Tuya devices, so if you don't want to open them up to flash directly, you can attempt to use tuya-convert to initially get ESPHome onto them however recently purchased devices are no longer Tuya-Convert compatible. There's useful guide to disassemble and serial flash similar switches here. After that, you can use ESPHome's OTA functionality to make any further changes.
- Put the switch into "smartconfig" / "autoconfig" / pairing mode by holding any button for about 5 seconds.
- The status LED (to the side of the button(s)) blinks rapidly to confirm that it has entered pairing mode.
Basic Functionality with Status LED inverted and cycling up through speeds
