    Control your thermostat from anywhere - in your home from an Insteon Keypad or on the road from your Smartphone with the Insteon Hub.

    System Support

    Our range of thermostat offerings ensures that even the most custom HVAC installation can be controlled.


    Insteon Thermostats fully integrate with your Insteon automation system. Automatically control duct dampers, ceiling fans and more.


    When one thermostat isn't enough, add Insteon Wireless Thermostats for additional temperature monitoring and throughout-the-home control.

    Smartphone Remote.

    Because carrying the thermostat around is just silly.

    When you install an Insteon Thermostat in your home and link it to the Insteon Hub, every smartphone and tablet you own becomes a remote control. It doesn't matter if you're hiding under the covers on a cold winter morning or running late out of the office on a sweltering summer evening, you can adjust the temperature from anywhere and ensure that your home is comfortable all the time.

    Winter Weather Watch

    Keep the blizzard outside and ensure your home is toasty warm by turning up the heat remotely.

    Summer Sun

    Cool down the house when you're on your way home on a blistering summer afternoon.

    Bon Voyage

    Turn off the AC even after you've left. Especially helpful for impromptu expeditions.

    Control on Apple Watch

    With the Insteon App on Apple Watch, you don't even need to reach for your iPhone to adjust the Thermostat. Change your Thermostat mode right on your wrist. (Disclaimer "Mode control only. Set point and fan currently unavailable from Apple Watch. Feature will be added in a future software update.”)

    Supported Systems

    A wide range of heating and cooling devices.

    Insteon Thermostat works with most heating and cooling systems found in homes and many businesses. With the exception of heat pumps and sophisticated triple-stage systems, your home's heating and cooling system is most likely compatible with Insteon Thermostat. In addition, Insteon Wireless Thermostat gives you control over line-voltage and millivolt heaters.

    Insteon Features

    Buy the NEST instead Review by Melisa
    Buy the NEST instead

    It is OK.

    I am very disappointed that I can't add thermostat settings to a scene - even thought the manual states: The SET works like the SET button on other Insteon devices and is used to add your Insteon Thermostat to a scene.

    I have the same issue with the door lock controller.

    Both sound better before you buy them.

    Worthless piece of Review by Matt
    Worthless piece of

    I started an Insteon system with the idea of eventually adding the thermostat. I love the light and camera controls. But the thermostat is a worthless piece of something dirty. Installation was easy. But the timer setup is not intuitive; I can't set up timers while being in just the Heat or Cool, which means that if you aren't careful, you could end up programming the thermostat to run the furnace and AC in the same day when it is not necessary; the thermometer often is not accurate. Also, the programs often the way I set them up. I can change a program and it will not take effect for a few days. Other times, the thermostat is set in a way other than the way I set it. Finally, while I can change the current temperature setting through the app, I cannot change the settings through the app. I will be looking for a different thermostat brand,

    Installation Instructions Omitted an Obvious Solution Review by Ronbo
    Installation Instructions Omitted an Obvious Solution

    After receiving my Insteon 2441TH Thermostat and removing my old stat I was perplexed as what to do since my old stat used only 4 wires and the Insteon requires 5. The docs said in such case I needed an "Add-a-Wire" device. Upon looking at the docs for that device and finding them totally confusing and not wanting to spend an additional $25 plus shipping I looked for a better solution, which it turns out is simple.

    The "5th" wire required is just a common wire back to the other side of the thermostat's power supply. Fortunately my stat location is on the other side of the wall from the AC unit. I was able to locate the "COMmon" terminal on the AC control board (the board where the existing thermostat wires terminate). I simply ran a single wire from that terminal to the "24COM" terminal in the 2441TH. The other 4 wires were connected as usual (Red->24 RH, White->W1, Green->G and Yellow->Y1). My unit is single stage only so W2 and Y2 are not used. I powered up and everything seemed to work (at least the AC... way too hot here in Houston to test the heat. I will wait til winter to try that!)

    FWIW, the reason a lot of systems have only the 4 wires is that before "smart" thermostats they were just dumb switches (typically with a mercury switch attached to a bi-metal coil) and did not need their own power to work. Even so, the "common" terminal will always be there on the control panel since that is required to activate the relay at the compressor unit.

    I could not find any instructions as simple as what I have expressed here anywhere on the web so I had to figure this out on my own, which of course I could do since I have a degree in Physics from a prestigious Southern university.

    Don't do it! Review by Todd
    Don't do it!

    Look, I love Insteon products overall as it's a great way to access your devices remotely, but there are many products that do that now. The issue I have with these is that they don't hold up. I have 8 zones in my house, 6 of them are this thermostat. I had them all going for years, then along comes maybe a 3rd or 4th power outage over those years and it blew 3 of them out. I checked the controller downstairs and the power supply which runs the 4 upstairs (one of them not this product), and the 1Amp fuse was still in tact, so somehow less than a 1Amp surge blew out all three of them, the 4th on that controller was NOT this product and it's fine. Don't wast your money. Get the more expensive ones.

    Not Impressed Review by Bill
    Not Impressed

    I purchased this unit with an understanding that I would have more functionality for a "smart" Thermostat. It is not a true smart thermostat. It only talks via RF to the HUB, which is fine. I can see my temperature and adjust on the fly with my Insteon App. However, you cannon make or adjust programs, set holds, or other settings via the app. It all must be programmed at the wall. It has less programming function capability than the 7-day programmable that I replaced it with. It is not intuitive to operate and I cannot get the Hold setting to work properly as it only "Hold"'s in Auto mode, when both temperatures are tied together. So when I want to Lower the heat to 63, it also brings down my cool to 73, not so great.
    Needless to say, I am pulling it off the wall and putting my 7-day "dumb" programmable back on until I can get my hands on a Nest smart thermostat.
    Overall, disappointed and would not recommend. I would return, except that I am 7 days past the 30 day window.

    Insteon Thermostat Review by C.
    Insteon Thermostat

    This installed easily, programming was straightforward, was discovered on network without any problem. Appearance is neat, connections clearly labeled. I'm happy to have this (especially at a recent sale price).

    My observations:
    - I agree that it would be nice to have a button that would light the screen on the first tap, without changing any setting. I have tried the "mode" button for this, to avoid changing set temp until I can see screen clearly, just noting.

    - Very cool to be able to see temp (and humidity) as well as view and change set temps from my phone, wherever I am.

    - The program schedule runs when the thermostat is set to "auto," but not heat or cool. Using "auto" appears to mean that my system could switch between heat and A/C on its own. That is new for me, will need to make sure my temp settings work with this arrangement. The remote capability will be very helpful for that.

    Insteon Thermostat Review by paul
    Insteon Thermostat

    I purchased two of these, one for downstairs and one for upstairs. The temperatures are not accurate, as a matter of fact both are about 3 to 4 degrees higher than what they show. I have carbon monoxide detectors which also display the temperature and they're both 3 to 4 degrees less than what my insteon thermostat says and they matched my old ones.. They get stuck in different modes when using the auto programing mode which does not make sense.. I am not pleased with them, only had about six weeks and if I would like my money back.

    Nice Thermostat Review by Paul
    Nice Thermostat

    5 min install, works perfect with ISY. Got 2 of these on a Black Friday sale. Was able to set max and min limits on temp with ISY programs. A perfect solution with unlimited possibilities with simple ISY programs.

    Very unreliable product, doesn't communicate via RF Review by Brock
    Very unreliable product, doesn't communicate via RF

    If you use this as a 7 day programmable thermostat it is probably fine.

    If you buy it to use it as an Insteon device to control the way you intended beware, it is the /worst insteon device out there/. I have over 50 devices, all work well, several as dual-band devices less than 10' away from this thermostat and it would have trouble communicating. Over time it got worse, couldn't write updates (in ISY 994i log) , unlinked, re-linked, still unreliable.

    The thing that fixed it was a factory reset (in the manual on this site) that helped and made it reliable again, but only worked for a limited time.

    I really hope Insteon/SH phases this out for modern features like Nest with built in motion detector, better humidifier control, modern UI. I would given the quality of the other products swap this awful thing for a complete rebuild if it had other features built in.

    Humidity control needs to be advertised Review by James E
    Humidity control needs to be advertised

    Fantastic thermostat. I have been using two with hot-water-heat since September 2015. I use House Link and change the set-point roughly 20 times per day.
    One under-advertised feature is that the T/S will control humidity. I use that feature to control the bedroom humidifier.
    With the lower price, I just purchased two more.
