Sensi Touch 2 Smart Thermostat with Touchscreen Color Display, 100 Years of Expertise, Programmable, Wi-Fi, Data Privacy, Easy DIY, Works with Alexa, Energy Star Certified, ST76W, C-Wire Required

So far it is working really well. My old Honeywell/Resideo thermostat would take too long to register temperature changes so it would say 74 when it had reached 76 and then it would drop to 72 before the display would update to the new temperature.This one quickly responds to changes so there aren't the wide swings in temp. It is really easy to read and doesn't flood the hallway with light. It has a classy appearance and it is very easy to use, as is the app.

This device is 100% better than my old thermostat.It has great features. Setting up, or editing a schedule was tedious and frustrating with tho old device, and there were only four set points available; sleep, wake, leave and return. I always wanted at least one more time slot. Well, now I have as many as I want.Installation was really easy due to the very detailed instructions, which also provided help with any problems that you might encounter.You can set options directly on the thermostat or through the app. Every option is available either way.The only issue I had was setting up Wi-Fi. I kept losing the connection. I would stumble through the installation, perhaps get connected, only to have it fail, or just have the sequence say "unable to connect: after spinning it's wheels for minutes at a time.IMPORTANT NOTE:I discovered two things that weren't made clear:First, there is a pin number for the setup. You can access it where the QR code display pops up. If you scan the code, it takes you to a web page that I didn't find particularly helpful. But you can bypass scanning the QR code and access the pin directly for a more direct path to the setup. If I remember correctly, below the QR code, the pop-up says something like 'scan the code or use the pin.' If you want a thorough explanation, click "Use the pin." Good for an initial setup, but mostly unnecessary for repeated attempts.Second, the pin CHANGES, apparently on each failed attempt. At first, I copied the pin and re-used it, thinking it was static. It took several failures before I noticed my copied pin was different from the pin presented with each failure. So some of my frustration was from this little mistake in my original assumption. I'm not sure if the pin changed once I got the Wi-Fi established. It's been stable now for at least 24 hours.I really love this device! I wish Amazon carried the remote sensors for this thermostat.Addendum:Shortly after I wrote this review, I found the Sensi remote room sensors available for less than $40 each, so I bought two for about $80 + tax, Free delivery slated for about 7 days, but they arrived early; in just two days. I was very pleased. The uneven cooling of remote rooms has much improved.I didn't think I'd use the app much, but it's very handy for quick changes when I'm working at my desk or reading, watching TV or in bed. I actually use it a lot. It's been about a month and the Bluetooth connection has been steady and very reliable.It was a great improvement and an excellent investment.

Climate control is no longer a strictly private endeavor in the modern age, and that's a shame. I don't want to share my personal data, proclivities, or whereabouts with my thermostat manufacturer. Nor do I wish to have said data monetized, and sold to anyone. As such, privacy becomes a major concern when selecting a thermostat in our modern age. That's what brought me to Sensi... and I'm GLAD to have found this product. No glaring exploitations, AND I now have VASTLY SUPERIOR COMFORT, usability, and efficiency compared to my last G****e unit.My primary concern was maintaining information privacy, yet I also needed a system that insured comfort, while allowing remote use. I found this Sensi thermostat after much searching and careful research, and I couldn't be happier with the outcome. I had my A/C contractor install it, and it took him about 20 minutes in total. After setting it up (firmware adjustment) with my system, it has worked flawlessly. It took me about a day to design a programming schedule that would keep our home comfortable throughout the week... and I've been thrilled with the results. Our home has never been so comfortable at all hours of the day! It has been remarkably cool, in spite of record high temperatures over the last 3 days. I'm TRILLED!It's super easy to program. The native application is easy to use, and flawless in operation. Connection is rock solid via Wifi6. No loss of programming. Almost instant access, and response. I love that this device doesn't think it's smarter than me. It GIVES ME THE CONTROL over the system and operation... not some godless corporation in silicon valley. The choices are MINE, and not made for me. HUGE plus!This Touch 2 also allows for the addition of wireless (battery operated) remote sensors to be placed in the home for added control. I added one ($40 each) to my (frequently warmer) master bedroom, and it has wildly improved comfort in that room. I added it myself, it was an absolute breeze. It has performed flawlessly since install. Two AA batteries are WAY easier to replace than running a wire through my attic. This is a total DIY WIN!I couldn't be happier with this purchase, and it gets a GLOWING 5-star rating with TWO BIG thumbs up! Kick that spyware demon out of your nest, and get the BEST climate control on the market! Wildly better, greater comfort, and simply SMARTER than the rest... by not trying to outsmart you.

This was easier than I expected to install. I did purchase an additional plate because I was replacing a thermostat that was larger than this one. I love being able to adjust from my phone without having to get up and down. Connection to my WiFi was simple. Instructions very clear. I haven’t noticed a change in the humidity. I am considering getting sensors to balance the temperature throughout the house. Works as expected and I am pleased with my purchase. It controls the temperature to my settings effectively.
