How to use device type specific configuration

identify_timeout: Sets the duration of the identification procedure in seconds (i.e., how long the device would flash).The value ranges from 1 to 30 seconds (default: 3). The value must be a number with a minimum value of 1 and with a with a maximum value of 30
state_action: State actions will also be published as 'action' when true (default false). The value must be true or false

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}.

Power-on behavior (enum)

Controls the behavior when the device is powered on after power loss. Value can be found in the published state on the power_on_behavior property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"power_on_behavior": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"power_on_behavior": NEW_VALUE}. The possible values are: off, on, toggle, previous.

Water leak (binary)

Indicates whether the device detected a water leak. Value can be found in the published state on the water_leak property. It's not possible to read (/get) or write (/set) this value. If value equals true water leak is ON, if false OFF.

Identify (enum)

Initiate device identification. Value will not be published in the state. 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 {"identify": NEW_VALUE}. The possible values are: identify.
