Notes

Protection

ZigBee 3.0, monitoring and cuts power if too high temperature or if overloaded.

Pairing

Factory reset by press & hold the power button for 12 seconds. The LED is then starting to blink 3 times RED in intervals during pairing process.

Specs

  • Rating: 220-240VAC, 16A, 50Hz
  • Standby Power: <= 0.5W

Options

How to use device type specific configuration

  • 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

  • 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

  • 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

  • temperature_calibration: Calibrates the temperature value (absolute offset), takes into effect on next report of device. The value must be a number.

  • temperature_precision: Number of digits after decimal point for temperature, 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

Exposes

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.

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.

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.

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}.

Temperature (numeric)

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

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, previous, on.
