Im going to leave it with current setup (allowing state modification on the children) for now, after Ive lived with it for a bit I’ll see if I actually ever accidentally change the state manually. I agree it shouldnt be possible on their published devices and hence there is some merit in trying to get ST to update their published DTH, but I guess it is useful for testing (e.g. I dont want to have to trigger my doorbell/alarm/… every time in order to check that it is triggering the right CoRE routines…)
