Notes #

Deprecated click event #

By default this device exposes a deprecated click event. It’s recommended to use the action event instead.

To disable the click event, set legacy: false for this device in configuration.yaml. Example:

devices:
  '0x12345678':
    friendly_name: my_device
    legacy: false

Pairing #

Press and hold the button on the device for +- 10 seconds (until the blue light starts blinking and stops blinking), release and wait.

You may have to unpair the switch from an existing coordinator before the pairing process will start.
