If no one interacts with Alexa for a while at night, she might have a hunch everyone is asleep. When someone interacts with Alexa or uses smart devices, she can tell that someone is home. Alexa learns from your daily interactions and improves over time.

There was a problem filtering reviews right now. Please try again later.
I am so pleased with my decision that immediately after installing it, I bought a second on for upstairs.
Installation was easy and took about 15-20 minutes to install and set up in the app. The unit mounts with 3 screws and anchors, a small screwdriver tool and an optional wall plate. A word of advice - use a better screwdriver because the included tool isn’t great. You’ll also need a drill with a 3/8” bit to assist with the wall anchors.
Some of the reviews I read mentioned that people had trouble with the app recognizing two thermostats, that was not the case at all with me. It was extremely easy to differentiate in the app and just as easy to control each one.
Another review that made me worry about buying this thermostat was that you couldn’t simply tell your Alexa device to adjust the temperature, and that you had to open the app to make adjustments. This problem must have been resolved or a solitary issue because ours works just fine with voice commands.
This thermostat does not offer a sensor option to monitor a particular room or area, so if you’re looking for that, you may need to look at other options.
As far as smart settings, you have two options. Alexa can learn your routines and track your phone’s location to adjust the temperatures accordingly when you’re home or away. This works best when everyone in the household connects to the app and consents to tracking. It will even adjust the temperature to your desired settings when you’re within a certain range of your home.
If this option isn’t for you, it will allow you to set schedules and desired temperature ranges throughout each day of the week. But you’re still able to log into the app and make adjustments when needed.
My last tidbit of information is regarding the second unit that I bought, it was a “renewed unit” and priced at $40. It’s absolutely perfect and I couldn’t tell the difference between it and the new one, it came with all new mounting hardware and was just as easy to install as the first one that I bought.
Setting it up was a breeze, thanks to the straightforward instructions provided by the Alexa app. Within minutes, I had the thermostat up and running, putting me in control of my home's climate. What's more, receiving information about potential energy rebates from Amazon after my purchase was an unexpected bonus, showing their dedication to helping customers like me save money and reduce our environmental footprint.
Additionally, for those considering DIY installation of this thermostat, YouTube videos can be a helpful resource to check furnace wiring, particularly for the C wire (usually blue). If you're unsure or encounter difficulties, it's wise to call a technician for assistance and ensure a smooth installation process.
But the real magic began when I started using the automatic comfort feature powered by Alexa. With just a simple voice command, I could tell Alexa my preferred temperature settings, and it would effortlessly adjust the climate of my home accordingly. Whether I was relaxing at home or out and about, I could trust Alexa to keep my living space comfortable while conserving energy.
And when I needed to make adjustments on the go, the Alexa app became my go-to solution. With just a few taps on my smartphone, I could easily control the temperature from anywhere, ensuring that I always returned to a cozy home.
What truly sets the Amazon Smart Thermostat apart is the peace of mind it offers. With its reliable performance backed by Honeywell Home Thermostat Technology and Amazon's exceptional customer service, I feel confident knowing that my home's climate is in good hands. It's not just a smart upgrade for my home; it's a personal investment in comfort, savings, and sustainability.
If you're considering upgrading your thermostat, I highly recommend the Amazon Smart Thermostat. It has truly exceeded my expectations, and I can't imagine life without it. Trust me, you won't be disappointed.
