Rollershutter RS3 same devices different behaviour

Hello dear openHab community,

I’ve got a problem that drives me crazy. I read a lot about similar problems in other threads but all the solutions didn’t work for me.

My settings:
openhab version: 3.2.0
hardware: RasPi 3B+
two Fibaro Rollershutter RS3 - FGR 223 (zwave_version 5.1)
both devices have the same following properties (of course the zwave_nodeid is different)

→ the devices channels “blinds control” (not the deprecated one) are implemented as dimmer and the are shown as slider at the sitemap

For me both devices and items are build identical.


My problem:
One items/device is working pretty well and the other almost not at all.

Changing the not working one (Küchenfenster) results in the following logs:

2022-11-03 18:42:08.057 [INFO ] [openhab.event.ItemCommandEvent      ] - Item 'ZWaveRS3EGKuchenfenster_BlindsControl' received command 6
2022-11-03 18:42:08.059 [INFO ] [penhab.event.ItemStatePredictedEvent] - Item 'ZWaveRS3EGKuchenfenster_BlindsControl' predicted to become 6
2022-11-03 18:42:08.066 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'ZWaveRS3EGKuchenfenster_BlindsControl' changed from 5 to 6
2022-11-03 18:42:09.660 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'ZWaveRS3EGKuchenfenster_BlindsControl' changed from 6 to UNDEF

→ Each value above 0 opens the real blinds to max opening (like 100%)
→ Value 0 closes the real blinds (0%)
→ No position between 0 and 100 is possible

Changing the working one (Arbeitszimmer) results in the following logs:

2022-11-03 18:42:25.694 [INFO ] [openhab.event.ItemCommandEvent      ] - Item 'ZWaveRS3EGArbeitszimmer_BlindsControl' received command 20
2022-11-03 18:42:25.697 [INFO ] [penhab.event.ItemStatePredictedEvent] - Item 'ZWaveRS3EGArbeitszimmer_BlindsControl' predicted to become 20
2022-11-03 18:42:25.704 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'ZWaveRS3EGArbeitszimmer_BlindsControl' changed from 24 to 20

→ Opens the real blinds like expected

I also tried to implement the items as rollershutter and sitemap as default (like mentioned here: Problems with brandnew FGR223

I don’t know what to do and don’t know why “Küchenfenster” results in UNDEF.

Thanks for your help !
