from 6105 reviewsSuper easy setup! I'm a big fan of Mysa
Does a better job than the other smart thermostats I've used and the app gives you all the information you need to make the best use of your home heating dollars.
Love the sleek more modern look of these! The ability to control them remotely from your phone, set schedules and lock them is fantastic. You’d never know they were plastic they look and feel so nice.
My new Mysa works perfectly!
Excellent product, already have 5 of them plus these new ones, I will cover my entire home! So happy with my Mysa thermostats!
Facile d’installation et a configurer sauf horaires quand a 2 plus difficile a configurer. Pas majeur.
Easy to install. Replaced a defective non-Mysa unit without any problems.
Love the thermostat. Great design. East to use. Only slight issue is the touch screen. To activate the up and down temp selection the area to tap on the arrow is extremely small.
I’m satisfied. It’s easy to install, well designed, and does everything it’s supposed to do
Works as expected…finally got rid of the junky 1980’s thermostat that only heated to the max temp
Très bien emballé et belle présentation
Replacement unit was sent immediately after contacting customer service. My interaction with them was very professional and informative
Awsome product. I love it!
Relatively easy to install and like the ability to turn down the brightness of the display, including turning it off completely. App is easy to use.
