Mostly good... but frustrating when it’s not

We had three 3M 50 Filtrete thermostats installed in our home 7 years ago. For the most part, they work very well and this app is easy to use. Except one of them has lost WiFi connection several times. Resetting it doesn’t work. I have to reinstall it in the app as a new thermostat, which loses our scheduled heating/cooling times, plus the history of our usage.

It just happened again this past weekend. Very frustrating. I am not likely to get this brand again when it comes time to replace my thermostats.

It has been a great six year experience. It worked perfectly. I had good WIFI service and I suffered no connection losses. In fact My 3M-50 Thermostat acted as a power monitor and boiler monitor. When I was away from home, using my Iphone App, the Thermostat doubled as a house monitor. When it was off it meant that power had failed. I checked with Utility acompany to confirm. It was always true. If space temperature was below set point it meant the boiler was out. I would call my daughter who leaves nearby to have her restart boiler, check fuel level or call for service. I saved a lot of energy with automated “away” temperature reset. The cost of the unit is very competitive. Everybody should have it and take advantage of its usefulness.

The only App with the best exclusive feature!

I have used several smart thermostat apps (ex Emerson,ecobee, Honeywell) that are newer and prettier then the 3M CT50 that came with this app. But I ended up going back to this feature filled app. This app is very comprehensive and intuitive. And the best think that I love is the “Runtime per hour” features which keeps track of how many minutes it runs per hour. It also puts in a graph with bars in minutes. The apps stores this information for as long as you own the app so you can review all your info for years back. No other app has this feature.
