Tom,
We have the one, but only paid $125.00 for it from Amazon. Cell phone app, lets us control it from anywhere. It will also tell you what the current temp is at the thermostat. Hooked up myself. You need Internet access to you home, and a Wifi router.

I think Lowe's and Home Depot also sell same thing from 3M.
