The Honeywell Wi-Fi Thermostat is for you if…

  • You favor tighter control over the temperature
  • You want the emailed alerts so you know when your house has lost power or is colder than you expect
  • You like to control things from the wall unit itself (you can still do these things on the app and website, too)
  • You just don’t like the Nest’s minimalist design aesthetic
  • You don’t like Google for whatever reason (privacy concerns, perhaps)

Did you try a Nest and it didn’t work out for some reason? Some homeowners who had difficulty installing a Nest switch to Honeywell Wi-Fi without problems. (You will need a C-wire, though.) The only real drawback of the Honeywell is the lack of monthly usage reports.

How much should a Honeywell RTH 9580WF thermostat cost? with installation ? What is a C wire? I want to be able to adjust Humidity levels in Florida

According to Honeywell tech support, you CAN use an RTH9580WF without a C-wire, at least in my application (forced-air electric heat and A/C. You need the THP-9045 wiresaver module which can be had on Amazon for about $20.

I have an old Lennox 80% furnace. I am looking for controlling my furnace remotely over smart phone. Can anyone tell me if any of these Thermostats ( Nest Learning Thermostat T200577 or Honeywell Wi-Fi Thermostat ( RTH9580WF ) will work ?
