  • Reduce energy costs with geofencing, scheduling and remote access
  • Works with Apple HomeKit, Amazon Alexa and Google Assistant
The Sensi Touch Wi-Fi smart thermostat puts comfort control at your fingertips whether you are at home or on-the-go. Just a tap of the easy-to-use touchscreen display or free mobile app lets you remotely access, change or program your home temperatures. Anytime. Anywhere. Sensi mobile app guides you through each step of the DIY installation process. A common wire (c-wire) is required for all system types. Refer to our online compatibility resources on our website to make sure Sensi thermostat will work in your home. Once your Sensi thermostat is up and running, you can let your location automatically adjust your temperature settings with geofencing or use the intuitive controls to create a custom schedule, to save about 23% on your HVAC energy usage. Energy savings calculated by comparing operation time for a nationwide sample of Sensi users with temperature adjustments averaging 4° F vs. users with no adjustments. Savings vary based on equipment type/condition, insulation, climate & temperature adjustment size/frequency. Based on survey results of 2120 respondents that purchased and installed a Sensi thermostat in 2018, approximately 70% reported installing in 30 minutes or less. Adding a common wire may impact installation time. Does not work with electric baseboard heat and some other systems. System requirements for mobile app: iOS - 10.0 or above Android - 4.2 or above (5.0 or greater to use the Geofencing feature).

I'm frustrated. I installed the unit as instructed but the device does not come on. I connected the red wire to RH and RC, no power. Then I inserted the red wire into C, a white light flickered for a second on the display. Nothing. There's a blue wire -- where do I put that blue wire?
Asked by: Skipper
I would recommend watching the various videos and figuring out which way your particular system is wired. It's a little tricky.Don't skip anything!

Does this require batteries?

Does this require batteries?
Asked by: Ronnye
No batteries required! This unit taps into the HVAC's 24 Volt DC system to power the thermostat. If you HVAC does not have a "C" wire in the wall there are two options to wire the unit; Plus the ability to purchase a separate 24v supply. If you HVAC is less than 15 years old, it's likely compatible with Sensi. This unit works exactly as advertised and support is fantastic. Real people who understand the language and can diagnose almost any system issue.

Sensi Touch Wi-Fi Thermostat with Touchscreen Color Display is rated 4.2 out of 5 by 187.

I have strong wifi signal but after their last software update there has been nothing but headaches with this thing, under wifi setting it says i am connected to wifi but cant connect to sensi cloud. save your money and dont buy this one tech support no help web page no help they will tell you to reboot your router (didnt work) or re do the wifi settings (didnt work) or they will blame your provider or router which i know is not the case cause all my other smart home devices have no issues including my nexx home garage door opener. maybe if they ever fix their servers this thing will work again but now its just a normal everyday thermostat not a smart device! hopefully i can still return it and get my money back

Installation was straight forward and easy up until the point where you use your phone or tablet to connect the stat to your router. I work in IT, i'm no slouch when it comes to computers and networking but I tried 3 different android phones and one tablet and every single one failled on that step with error message "provisioning error". None of the suggestions provided by support rectified the issue. On top of that it short cycled my unit, 5 minutes on, 4 minutes off and repeat. I read in the support docs that there is a setting to prevent short cycling that can only be changed with the app when the stat is connect to the internet. I connected thermostat to box, box to store and money back on my credit card. problem solved.

I can't attest to longevity, but there is a very important step that I missed the first time. This t-stat doesn't have batteries to power it. You must have a constant power source coming in from your HVAC unit. I have a 4 wire system. You have to hook up a 5th wire that (in my case) is already included in the cable coming from the unit. Hook the 5th wire up to the "C" terminal on your HVAC circuit board and the other end to the "C" on the new T-stat. If you miss this step, you'll be returning it to Home Depot telling them it doesn't work like many of the 1 star reviewers. I was almost one of them.

(The extra holes in the picture was because of something else I had installed previously in this spot.) It took maybe five minutes. Setup was just as easy. My wife and I are always at each other about how cold or hot it is in the house. She likes it cold and I prefer it warmer. We were constantly getting up to check what the temperature was in the house. We no longer have a feud over the thermostat. Best of all we can control it while we are away from the house and before we return to the house. It was a little pricey; however, I think the savings in the long run will outweigh the cost. It's great.

Rated 5 out of 5 by from Awesome product This is a great thermostat and it comes with great instructions and support. My old thermostat had a wiring pattern different than the app would accept. I emailed support with a couple pics of the old thermostat and the wiring pattern. A couple days later I get all the information and the Sensi is up and running. Great product!

I've purchased 2 units and the GeoFencing feature alone will pay for this thermostat. But the support bu the OEM is why you need to purchase this fantastic tool. Simple to use: Yes Easy to install: Yes Great support: Absolutely I can not recommend enough this product.

Thermostat was showing 84 but was set to 77 AC running but would not go down. I had to call Tech support several times. They reprogrammed it and made a few changes. Blue screen when it’s cool and gray when cooling. Works sometime.
