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}.
Power outage memory (binary)
Enable/disable the power outage memory, this recovers the on/off mode after power failure. Value can be found in the published state on the power_outage_memory property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"power_outage_memory": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"power_outage_memory": NEW_VALUE}. If value equals true power outage memory is ON, if false OFF.
Device temperature (numeric)
Temperature of the device. Value can be found in the published state on the device_temperature property. It's not possible to read (/get) or write (/set) this value. The unit of this value is °C.
Flip indicator light (binary)
After turn on, the indicator light turns on while switch is off, and vice versa. Value can be found in the published state on the flip_indicator_light property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"flip_indicator_light": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"flip_indicator_light": NEW_VALUE}. If value equals ON flip indicator light is ON, if OFF OFF.
Operation mode (enum)
Decoupled mode for button. Value can be found in the published state on the operation_mode property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"operation_mode": ""}. 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.
Mode switch (enum)
Anti flicker mode can be used to solve blinking issues of some lights. Quick mode makes the device respond faster.. Value can be found in the published state on the mode_switch property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"mode_switch": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"mode_switch": NEW_VALUE}. The possible values are: anti_flicker_mode, quick_mode.
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: single, double.
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.
