I am working on an Warema openHab2 binding for quite some time and it was realy hard for me to get used to the openhab binding coding.
This new OpenWMS binding should be compatible with the Warema WMS Stick (1002775), which contains both receiver and transmitter functions.
As you may know, the protocol for communicating the Warema WMS system is not publicly known and a documentation is not available.
However, some guys have read the communication of the WMS USB stick and decoded important commands to control the blinds, so that a basic basis for this binding has been created.
Thanks a lot for that, without this preliminary work, the binding could not have been developed.
It should be noted that this is still an early beta version of the binding and must be further developed in any case.
I have programmed the binding for my personal use but feel free to use it as well - but on your own risk.
You can find the current version here.
A precompiled version can be found there, too.
As I said, it will be further developed, errors eliminated and better intercepted. But I have only little time for it, so that unfortunately no significant support can be provided by me.
Please understand if it takes a few days to answer your questions.
Keep on coding.
