Switch (top endpoint)

The current state of this switch is in the published state under the state_top property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state_top": "ON"}, {"state_top": "OFF"} or {"state_top": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state_top": ""}.

Switch (bottom endpoint)

The current state of this switch is in the published state under the state_bottom property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state_bottom": "ON"}, {"state_bottom": "OFF"} or {"state_bottom": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state_bottom": ""}.

Operation_mode (enum, top endpoint)

Decoupled mode for top button. Value can be found in the published state on the operation_mode_top property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"operation_mode_top": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"operation_mode_top": NEW_VALUE}. The possible values are: control_relay, decoupled.

Operation_mode (enum, bottom endpoint)

Decoupled mode for bottom button. Value can be found in the published state on the operation_mode_bottom property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"operation_mode_bottom": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"operation_mode_bottom": NEW_VALUE}. The possible values are: control_relay, decoupled.

Power_outage_count (numeric)

Number of power outages (since last pairing). Value can be found in the published state on the power_outage_count property. It's not possible to read (/get) or write (/set) this value.

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.

Power (numeric)

Instantaneous measured power. Value can be found in the published state on the power property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"power": ""}. It's not possible to write (/set) this value. The unit of this value is W.

Energy (numeric)

Sum of consumed energy. Value can be found in the published state on the energy property. It's not possible to read (/get) or write (/set) this value. The unit of this value is kWh.

Voltage (numeric)

Measured electrical potential value. Value can be found in the published state on the voltage property. It's not possible to read (/get) or write (/set) this value. The unit of this value is V.

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": ""}.
