Add device type 220 for pushbuttons #14
Description
Could you add the device type (220) for push buttons/rocker switches to the library? I'm hoping to update the xComfort HA integration and it would be much easier if this device type was already included.
I've tried to do a workaround, using @alex-w2's work as a reference in my own HA integration fork, but the way you you handle things in this library is quite different. I'm not exactly brimming with confidence to submit a pull request.
I'm not a developer and this is my first try at Python, but I'm motivated to contribute to the HA integration. I believe that concentrating on integration updates, rather than the library's inner workings, will enable me to contribute more directly and swiftly, easing my learning curve with both the library's structure and Python.
