I had a "bad" node like this in the past and I just eventually replaced it. However I am just sceptical that this is a software z-wave
issue as it seems to randomly affect nodes and when the node is on it will flutter on and off when it seems to be polled or when traffic passes through the node. I have no way of verifying this (to my knowledge) but has anyone else had this issue? I'd speculate a hardware failure wouldn't cause a light to flutter off and on but instead go dead or not respond at all. It still accepts z-wave control, but when it's on it has an undesired Halloween effect. Any ideas?
