Fibaro Single Switch 2 no longer responds to status (January 2020)

@steven.green, any idea why are those devices reporting any status from sourceEndpoint 1?

So far, the Switch 2 sends MultiChannel message with sourceEndpoint 1, what cannot be handled with the current if sourceEndpoint == 0, what is a reasonable condition.

The Dimmer Switch 2 sends also MultiChannel encapsulated messages and also with sourceEndpoint 1. More interestingly the destinationEndpoint is 1 as well, is that correct?

Is the Firmware development on a downhill at Fibaro or have they changed something with some newer firmwares and that’s why all these happening?
