Easy install, flawless app, LOVE OUR SENSI!

Easy install, flawless app, LOVE OUR SENSI!
We are OTR truck drivers and have been wanting to upgrade our thermostat so that we could control it over the road. After researching, and almost choosing another, we went with the Sensi. We were worried about install, but it only took my husband 20 minutes. Download the app first and it will walk you right through it. We did need a headlight and magnifying glass, but only because our old-ish eyes need a bit of help with small details. We love being able to monitor our home temp from anywhere, and modify if needed. The system is also not working as hard to maintain temp. The app is awesome, and allows us to see usage summary. I also love crawling into bed and not having to get up if it seems too hot or cold. Definitely recommend, and would purchase again.

Reviewed in the United States on February 10, 2024
Love it very much. Easy instal. Easy setup. Just did a few YouTube videos for educational purposes before it arrived. Was a snap. The Wi-Fi feature it awesome. I can monitor and control from work. When laying in bed if I get cold just reach for phone and turn on heat. Reminders can be setup for filter changing. Displays humidity levels in the house. Has options for setting fan to run every now and again to keep house air circulating. Has a base light to turn on to be kind of a nightlight in a dark hallway. I would recommend to anyone who would like a nice looking and very functional thermostat.

5.0 out of 5 stars Indispensable!
Reviewed in the United States on January 24, 2024
I sometimes wonder how other folks do without one of these!

I have lived in Arizona and Alaska and in both locations this gem saved me $$$$

First off, the install is very easy. I’ve done this in 2 different houses with different HVAC systems and had no problem at all.

The best part is being able to control my thermostat from anywhere. The app lets me do a schedule or wing it. It also has a setting to allow the heat or AC to cut off and fan out the “excess” (I’m sure there’s a better way to say that). When I have used the customer service line, they’ve always been very helpful.

When I travel, I know exactly what’s going on, I can turn it off with the app and I also have it set up on my Alexa Echo Dot.
Laying in bed on a cold night and saying, “Alexa, 74 degrees please!”

This model is less expensive than Nest and is very durable and works with several smart apps. LOVE IT!!!!

1.0 out of 5 stars Niet geschikt voor gebruik binnen de EU
Reviewed in the Netherlands on June 1, 2023
Dit product is niet geschikt voor gebruik in de EU. Probleem begint al bij het registratie proces, daar loop je vast omdat registratie alleen voor USA en Canada mogelijk is. Het alternatief (Apple home) beschikt niet over alle functies voor optimaal gebruik en functionaliteit. Programma’s (schedules) maken is onmogelijk. Door registratie problemen werkt deze thermostaat (zonder schedules) alleen binnen je eigen netwerk omgeving en niet buitenshuis.
