## Exposes

### 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`

.

### 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`

.
