Notes

Issues

It's been reported that this plug automatically turns off by itself if it looses the connection to the coordinator (e.g.: weak signal). So, a loop task that sends a turn on command would be a possible workaround.

Pairing

Press and hold the button on the device until the blue light starts blinking, release it and and the device will automatically join.

This option allows the device to restore the last on/off state when it's reconnected to power. To set this option publish to zigbee2mqtt/FRIENDLY_NAME/set payload {"power_outage_memory": true} (or false). Now toggle the plug/switch once with the button on it, from now on it will restore its state when reconnecting to power.

OTA updates

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

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
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
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

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 (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.

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.

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.

Consumer connected (binary)

Indicates whether a plug is physically attached. Device does not have to pull power or even be connected electrically (state of this binary switch can be ON even if main power switch is OFF). Value can be found in the published state on the consumer_connected property. It's not possible to read (/get) or write (/set) this value. If value equals true consumer connected is ON, if false OFF.

LED disabled night (binary)

Enable/disable the LED at night. Value can be found in the published state on the led_disabled_night property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"led_disabled_night": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"led_disabled_night": NEW_VALUE}. If value equals true lED disabled night is ON, if false OFF.

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.

Auto OFF (binary)

Turn the device automatically off when attached device consumes less than 2W for 20 minutes. Value can be found in the published state on the auto_off property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"auto_off": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"auto_off": NEW_VALUE}. If value equals true auto OFF is ON, if false OFF.

Overload protection (numeric)

Maximum allowed load, turns off if exceeded. Value can be found in the published state on the overload_protection property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"overload_protection": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"overload_protection": NEW_VALUE}. The minimal value is 100 and the maximum value is 2300. The unit of this value is W.
