# Sonnen Binding

The binding for sonnen communicates with a sonnen battery.
More information about the sonnen battery can be found [here](https://sonnen.de/).

## Supported Things

| Thing Type    | Description                    |
|---------------|--------------------------------|
| sonnenbattery | Monitoring of a sonnen battery |


## Thing Configuration

Only the parameter `hostIP` is required; this is the IP address of the sonnen battery in your local network.


## Channels

The following channels are yet supported:


| Channel | Type  | Access| Description|
|---------|-------|-------|------------|
|batteryChargingState|Switch|read|Indicates if the Battery is charging at that moment|
|batteryCharging|Number:Energy|read|Indicates the actual current charging the Battery. Otherwise 0.|
|batteryDischargingState|Switch|read|Indicates if the Battery is discharging at that moment|
|batteryDischarging|Number:Energy|read|Indicates the actual current discharging the Battery. Otherwise 0.|
|batteryFeedIn|Number:Energy|read|Indicates the actual charging current of the Battery in watt|
|batteryDischarging|Number:Energy|read|Indicates the actual current discharging the Battery in watt|
|consumption|Number:Energy|read|Indicates the actual consumption of the consumer in watt|
