Has anybody had luck conncecting a Carrier Cor 7c thermostat to Xfinity Home? Xfinity states that the Cor line of thermostats is compatible (https://www.xfinity.com/support/articles/control-ecobee-app).  . ;Long story short, I can't get my thermostat to show up in the Carrier app after I lync my account with Xfinity home. I had a few calls with Carrier, they say that the 7C only is supported with a mobile app and is not supported by Xfinity!?
Your link didn't work for me; is this the device?
