Well the sleepy EZFLORA died outright. It will no longer respond to Insteon messages at all. I’ve tried a reset (hold set switch before plugging in and until 15 seconds have past) – it still won’t respond. The LED lights up when the set button is pressed but remains unlit otherwise. Type for RMA. The good news is that the other one is still behaving perfectly and has enough zones for me to get by until the replacement for the faulty one arrives.
Thanks so much for your help in this forum and others.
