Notes

Debounce
It is recommended to not use the debounce option for this device since this will prevent the single and hold_release actions from being sent.
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. If you can't do this, try to remove battery (if it has one), push the button (to completely discharge device), place the battery back and try pairing again.

Switch
The current state of this switch is in the published state under the state property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state": "ON"}, {"state": "OFF"} or {"state": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state": ""}.
On with timed off
When setting the state to ON, it might be possible to specify an automatic shutoff after a certain amount of time. To do this add an additional property on_time to the payload which is the time in seconds the state should remain on. Additionally an off_wait_time property can be added to the payload to specify the cooldown time in seconds when the switch will not answer to other on with timed off commands. Support depends on the switch firmware. Some devices might require both on_time and off_wait_time to work Examples : {"state" : "ON", "on_time": 300}, {"state" : "ON", "on_time": 300, "off_wait_time": 120}.
Operation mode (enum)
Decoupled mode. Value can be found in the published state on the operation_mode property. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"operation_mode": NEW_VALUE}. The possible values are: control_relay, decoupled.
Action (enum)
Triggered action (e.g. a button click). Value can be found in the published state on the action property. It's not possible to read (/get) or write (/set) this value. The possible values are: release, hold, double, single, hold_release.
Linkquality (numeric)
Link quality (signal strength). Value can be found in the published state on the linkquality property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.
