Something happened a couple of days ago that has affected some z-wave functionality. There are a number of issues starting to surface on here in relation to them.
I ask because I’m curious just how far reaching the issue is. Whilst I’m not sure this is the same issue affecting you its possible. To date there been a couple of users who have raised a ticket with ST support in the UK and been told that they won’t look at the issue because the device in question is unsupported. Are you in the UK?
