Boy, I really hate this wireless thermostat. I got a message for a low battery on 3/6/15. Just a couple of days after changing the batteries. The 24v power is still working, I've verified it. The thermostat remote system was working; as I tested it using my laptop while I was there. I've left and now a week later, I cannot do any remote changes to the thermostat. All attempts to alter the temperature have failed. I get a message: ISSUE: Thermostat update request failed.
What a piece of junk. Comcast Xfinity, "are you listening".
