    After trying several smart thermostats this unit really makes a difference in balancing temperatures throughout your home using the smart room sensors.

    Upgraded from the T5. The remote sensors are a nice addition allowing temperature control priority in specific areas during the day.

    Buy this and add sensors. This has been a great addition to our house. We use it to control a single unit for a two story home. It has saved us a ton of money and makes balancing the temperatures easy as pie by knowing which vents to close to keep rooms at similar temps.

    What a great idea being able to put another sensor in another room and being able to control it off just one thermostat

    Disappointed with this product from a company like Honeywell. We couldn’t get the temperature sensors to work properly. They were reading way off. The thermostat made our units run a lot more than necessary for some reason and there’s definitely no savings if you’re looking for it. The app is also a huge negative. Very buggy and difficult to use.

    Ive tried Nest, ecobee and this. What I like about the Honeywell was the room sensors. They were less expensive, looked nicer and used AAA batteries which are easier to find. The setup for honeywell was easier than the other two especially with the room sensors. What i hated… was the screen. I’m 6’1” and at the height of the Honeywell’s screen would be off. I would have to bend over read it clearly. I chose to go with the ecobee for a couple reasons 1) it integrates with more 2) The Ecobee premium is one of the only that shows you air quailty. 3) the screen was nicer.

    Before you buy you must know! You have about a 50/50 chance of being able to get the app to work with this thermostat depending on the type of WiFi setup you have. It will not work with mixed 5ghz/2.4ghz networks. You must have independent 2.4ghz and 5ghz networks in your house for it to work. I’m not redoing the network settings for every device in my house so I’ve resigned to not using the app and just controlling it at the thermostat. It functions well this way but the price premium I paid for app access is going unused and if you bought your router in the last 3 years you will most likely have the same problem.

    Just what I needed for away from home thermostat setting and where one room is hotter than the others.
