I have tried some EnOcean products but the results have very much been hit and miss...
The nodon soft remote works just fine.
Also a generic 4 button remote works well. But I sometimes get the wrong signal for a button press mainly because a press and a release give a signal. sometimes the release triggers a press on another button. This makes the remote not really usable.
I also have some window contacts that worked for a while but recently just stopped working. I thought the solar panel maybe was not providing enough power but I think the problem is the latest Loxone firmware.
Relays are trouble some to react to Loxone commands. I cannot properly program them using the learn in procedure as defined by Loxone. I can now control one relay but Loxone keeps telling me the device is not paired. But the channel 0 command is working on the relay. But when I try to program another relay it just doesn't work.
All in all very frustrating. On the website Loxone one lists a few EEP profiles for actuators. So I think the support for EnOcean is really non existent.
For instance the EnOcean VLD telegram is not supported....
All in all I would not advise to use the EnOcean extension.
