Treatlife SS02S 2-Way Wall Switch

Device Type: switch
Electrical Standard: global
Board: bk72xx

Notes

The 2 way switch does not have a power sense pin. To solve this issue, and allow the smart switch to be smart, this code turns the White LED on when the light is off and, led off when the light is on. This allows the LEDs pin state to be used as a power sense, to determine whether to turn the relay on or off.

Additional notes on flashing via USB with the esphome CLI:

  • Connect the UART bridge with the board connected to it, to the computer
  • Run esphome upload <configfile>
  • Press and hold the reset button on the board, then select port
  • Release the reset button
  • If you see errors like read failed: [Errno 6] Device not configured, try releasing the button 1-2 seconds later
