@chris dont want to spam you. but this is still not solved. I have exactly the same problem (like also discussed in Problems with states/events)
I switch my controller from uzb1 to aeotec gen5. I tried a lot zwave bindings from standard 2.2.0 to different 2.3.0 snapshots. I dont get the states from all my fibaro switchs. always, when I change something in my zwave configruation (a new binding snapshot, a new controller, including a new device, …) some fibaro switchs are working with state on switch_binary1 and 2 and some not. after changing something again, its randomly again some other fibaro where it is working and where not.
I spent a lot of time now in that and I’m nearly to discontinue with openhab because I dont want to buy new zwave devices to get this problem solved… ;(
