## Options

*How to use device type specific configuration*

`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`

`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`

`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`

`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`

## Exposes

### 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`

.

### 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`

.

### 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`

.

### 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`

.

### Meter id (text)

Meter ID (ID of device). Value can be found in the published state on the `meter_id`

property. It's not possible to read (`/get`

) or write (`/set`

) this value.

### 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`
