What Customers Are Saying

Customers overwhelmingly praise the thermostat for seamless Alexa integration, with voice commands like "set temperature to 72 degrees" making adjustments intuitive and convenient. Many highlight easy installation with clear app-guided instructions and a sleek, modern design. Reviewers value automated scheduling for home, away, and sleep modes, reporting lower energy bills and appreciating filter replacement alerts. Some note frustration with limited customization—only three preset temperatures and weekday/weekend programming—plus short heating cycles and confusing app navigation. Despite these drawbacks, most customers find it a worthwhile smart home addition.

Remote Controlled Thermostat

The Sensi Lite Thermostat was easy to install and it gives me peace of mind knowing that I can check my thermostat remotely. Additionally, there is an added benefit of allowing RG&E the capability of monitoring the system and advising me of problems. They also offer the opportunity to reduce your electrical bill in times of emergency with a rebate if you accept their offer.

Energy star, NO

Would Not Recommend

Got this thermostat because of the WiFi capability, able to see how much our HVAC system would run for that day, and change the temperature while we’re at work, etc . Followed all the instructions, contacted their tech support. It’s not worth it! It does not sense the temperature correctly. AC set at 68* and the system runs almost all day long. We have other thermometers in the house and they’ll show between 61*-64* and the AC is still running because the thermostat senses the set temperature as...

Great product

Would Recommend

Easy install of you know what you are doing. The first 2 installs went well, the third one i needed some help. This particular unit is for a vacation rental and it now allows us to control what renters can set it to a week a giving us the ability to change settings ahead of time when we come to visit.

So surprisingly bad

Would Not Recommend

1. It wasn’t following the temperature schedule. After searching online and trying lots of dumb things, I changed the time zone from ET to ET. Yeah. Then it worked better, but not always. 2. Some days the heat doesn’t turn on until I open the app on my phone. it’s supposed it heat up at 7am and preheat, but sometimes it will be 8 or 8:30 and it’s still reporting that the temperature is set to 59. Never know when I’m gonna come downstairs and it’s freezing. But somehow just the act of opening th...
