Thanks all for providing the additional information.
A brief update, the problem is more complex than expected and appears not to be caused by a change that can be resolved in the app itself.
This problem appears to be similar in origin to the problem as observed with the ROBBsmarrt app (both related to Z-wave plus S2 devices), where the remote / wall controller do not report into Homey, similar to the switches of this app not reporting their state updates to Homey.
Athom development is looking with highest priority into this issue within Homey’s Z-wave core and together with AutomateAsia we are supporting where we can.
I will provide an update as soon as possible.
