What it exposes
| Feature | Property | Values | Control |
|---|---|---|---|
| Power (l2) | power_l2 | W | read only |
| Voltage (l2) | voltage_l2 | V | read only |
| Current (l2) | current_l2 | A | read only |
| Temperature (l5) | temperature_l5 | °C | read only |
| Uptime (l4) | l4_l4 | s | read only |
MQTT: state and commands
Zigbee2MQTT publishes the device state to zigbee2mqtt/my_device (my_device is the name you give the device). An example message:
{
"power_l2": 12.4,
"voltage_l2": 230,
"current_l2": 0.06,
"temperature_l5": 21.6,
"l4_l4": 0,
"linkquality": 120
}
The device only reports data and takes no commands.

Home Assistant automation example
Zigbee2MQTT creates Home Assistant entities from the device name. If it is called my_device, an automation in automations.yaml can look like this:
- alias: "Room too warm"
mode: single
triggers:
- trigger: numeric_state
entity_id: sensor.my_device_temperature
above: 26
for: "00:10:00"
actions:
- action: notify.notify
data:
message: "Temperature above 26 °C"

How to pair it
- In Zigbee2MQTT click Permit join.
- Put the device in pairing mode: usually a long press of the reset button (5–10 s) until the LED blinks; bulbs: switch the power off and on 5–6 times.
- Keep the device close to the coordinator or a router while pairing.
- Give it a clear name: MQTT topics and Home Assistant entities are built from it.
Exact procedure and model notes: the device page in the Zigbee2MQTT docs. No coordinator yet: coordinator picker.
