# Senec Home Binding
|
|
|
|
Binding to request status information from Senec Home Batteries to allow home automation decisions based on your current energy management.
|
|
|
|
If your power feed is limited by regulations for example, you can switch on devices if a limited rate was applied by your Senec Home device.
|
|
In addition you can switch off devices if the power consumption is getting higher.
|
|
|
|
Examples: Lights, pool filters, wash machines, ...
|
|
|
|
## Supported Things
|
|
|
|
| Thing type id | Name |
|
|
|----------------------|-----------------------------------------------|
|
|
| senechome | Senec Home Lithium Battery, V2.0, V2.1 and V3 |
|
|
|
|
|
|
## Thing Configuration
|
|
|
|
demo.things
|
|
|
|
```
|
|
Thing senechome:senechome:pvbattery [ hostname="192.168.0.128", refreshInterval=60, limitationTresholdValue=70, limitationDuration=60 ]
|
|
```
|
|
|
|
If the thing goes online then the connection to the web interface is successful.
|
|
In case it is offline you should see an error message.
|
|
The refresh interval is 15 seconds by default, but you can optionally provide your own value adding the `refreshInterval` key.
|
|
|
|
The property `limitationTresholdValue` is used as threshold for channel `powerLimitationState`. It is combined with property `limitationDuration` (seconds) to define a stable status for power limitation. Therefor use `powerLimitationState` to trigger Events (switches) based on your current power limitation.

|
|
| houseConsumption | watt | Current power consumption of your house/living |
|
|
| energyProduction | watt | Energy generated by your pv / inverter |
|
|
| batteryPower | watt | Energy processed by batterie itself, for example while charging |
|
|
| batteryFuelCharge | percent | Fuel charge of your battery (0 - 100%) |
|
|
| batteryState | | text describing current action of battery (e.g. CHARGING) |
|
|
| gridPower | watt | Grid power level, negative for supply, positive values for drawing power |
|
|
| gridPowerDraw | watt | absolute power level of power draw, zero while supplying |
|
|
| gridPowerSupply | watt | absolute power level of power supply, zero while drawing |
|
