Zwave2 - Philio PSM02 Slim Multisensor: motion and door sensors seem to be linked

That device is a pretty old device and should also work with older zwave binding versions:

There was a bug present a couple of days long which should now be fixed, maybe you catched the wrong day for updating.

Make sure after updating the binding you are deleting the Thing and readding it.

Thatā€™s it. The most recent version of the binding solved my problem.

Case closed.

Thanks to everyone involved.
