Pinout:

  • COM: Ground, Tx, Rx, 3.3v
  • Boot: GPIO, Ground

Optional, but highly recommended, rule to disable the fan from running during a fire @ 182F, which is a feature from the stock firmware.

There are physical buttons on the device that were used for the pairing and testing on the default firmware. You can configure them as GPIO 27 to Button 1 and GPIO 26 to Button 2 but as this is a device that is living in an attic I didn’t.

The device also has a 3rd relay which isn’t used in this model which would be used for a medium speed using GPIO22.
