Add "Smarthome 2.0" support

[ChristophCaina]

In openWB you can integrate some Smarthome devices.
You can activate up to 9 devices within the openWB - and the openWB can controll them...

The following devices are supported:

This could be interesting especially for devices, for which we don't have an direct Integration in HomeAssistant - these are mostly some specific heatpumps vendors in my opinion.

The OpenWB could controll the device directly, for example based on the generated power from the solar... so the most interesting information would be the WhCounter for that devices - but we could also maybe control the device directly through a smart-button...

To receive values from the OpenWB Smarthome2.0 devices, the following topics can be used (example)
openWB/SmartHome/Devices/n/DailyYieldKwh (n = number of the device 1-9)

But is it possible to controll a device?
like activate / deactivate, and so on?
