Perfect little thermostat. So easy to use - from the actual thermostat to the app. (Making the schedule can be a little counterintuitive when you first try to find/set them though). I installed myself with no issues (once I figured out a few aspects of the older wiring). It has worked flawlessly with no issues. Touchscreen is perfectly responsive. Just enough info on thermostat to not be confusing. It has the capability to do “auto” so it will switch between heat and AC on those days that it’s below 40 in the morning but 70 during the day (spring and fall days here in WV, see pictures of usage. The days with both blue and orange are days it was set to “auto”). It works as long as the settings are more than 2 degrees apart. Usage report is interesting to have access to - nice extra feature. Seriously, I can’t be happier after 3 different Honeywells with some sort of issue or just being too “plain” for the cost. So glad I saved money and didn’t go for a more higher end thermostat.
Thank you for your feedback

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.

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.
