Notes

Pairing

To reset the device and start pairing, press the button on the device for 8 seconds. The led will turn on in red and then start blinking in blue while the pairing process is active.

OTA updates

This device supports OTA updates, for more information see OTA updates.

Options

How to use device type specific configuration

energy_calibration: Calibrates the energy value (percentual offset), takes into effect on next report of device. The value must be a number.
energy_precision: Number of digits after decimal point for energy, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3
power_calibration: Calibrates the power value (percentual offset), takes into effect on next report of device. The value must be a number.
power_precision: Number of digits after decimal point for power, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3
device_temperature_calibration: Calibrates the device_temperature value (absolute offset), takes into effect on next report of device. The value must be a number.
voltage_calibration: Calibrates the voltage value (percentual offset), takes into effect on next report of device. The value must be a number.
voltage_precision: Number of digits after decimal point for voltage, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3
current_calibration: Calibrates the current value (percentual offset), takes into effect on next report of device. The value must be a number.
current_precision: Number of digits after decimal point for current, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3
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}.

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.

Power (numeric)

Instantaneous measured power. Value can be found in the published state on the power property. It's not possible to read (/get) or write (/set) this value. The unit of this value is W.

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.

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.

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.

Switch type (enum)

Wall switch type. Value can be found in the published state on the switch_type property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"switch_type": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"switch_type": NEW_VALUE}. The possible values are: toggle, momentary.

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.

Current (numeric)

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

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.
