Fibaro FGS222 - not switching properly

I’m not sure about the buzzing, but if the items are really how you have them specified, then the first one is wrong. It has a space between the endpoint and the command - it should be a colon -:

Switch relay1 "relay1 [%s]" { zwave="3:1:command=SWITCH_BINARY" }
Switch Relay2 "relay2 [%s]" {zwave="3:2:command=SWITCH_BINARY" }

This might explain the feedback not working when you press the button - maybe. Alternatively, what association is configured for feedback to the controller?

(I’m not sure about the buzzing issue, but it doesn’t sound good!)

@ewgor:
your 2nd problem is related to the item configuration.
I had the same problem (see above).
You just need to change
zwave="3:1:command=SWITCH_BINARY"
to
zwave="3:command=SWITCH_BINARY"

somehow OH handles the first relay differently than the second (you need 3:2:command=… at the second)

Ah - good point and well spotted @NCO . I forgot that some of the newer Fibaro devices don’t seem to properly use the multi instance…

Thanks guys for help, I made the correction in the first item definition and now it’s updating well!
I still got the buzzing in the device but I took contact with the supplier and hopefully I’ll get a new one or at least a response.

Thanks for the help!
