I have one of the Honeywell WiFi units. It's great for adjusting the set point on the way home from holiday. Better yet, I was in the pit at a Candlebox show and got a high temp warning. I texted a friend who went over and confirmed the AC was not working. Right after the show I called an HVAC service who sent out a truck the next morning, replaced the blown cap, and my house was cooled off again before I got home.
