I have three units. They were working flawlessly. One is over a year old and one I received yesterday. I connected to the remotes and set their sleep mode to "pin". Both of them. Now they will not be found, and when I hook them to the PC they do not respond to any data.
I wired up buttons to Commission and Reset and followed all of the tactics I could find here. No joy. I added an LED to the Associate pin and nothing ever happens when I try to locate them or when I push the Commission button one to four times. The Sleep_rq pin is low and the Sleep pin is high, as they would be if the unit is not sleeping.
I'm out of ideas. Can anyone offer some suggestions, please?
