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

Device type specific configuration

How to use device type specific configuration

• legacy: Set to true to disable the legacy integration (highly recommended!)
