Here's my question:
I was hoping to get the Ecobee (or Nest) in order to be able to monitor house temperature remotely while travelling. I still have that requirement. If I buy an Ecobee or Nest, mount it on the wall and connect only power wires to it, can I use it to only monitor temperature? IOW the Infinity would continue to control the furnace/AC as currently but I'd be able to tell if the furnace wasn't working using the Ecobee/Nest temperature report. If this isn't possible, is there another way to accomplish this?
