I bought myself a smart thermostat & that was a single of the dumbest purchases I ever made.
It is not the fault of the thermostat, it is our internet.
The thermostat runs on wireless, you download the app & run the thermostat from your PC, kindle or tablet with wireless affixion. The thermostat then can do all sorts of amazing things. It learns a annually heating & air program. Set the thermostat by making adjustments as you go. The thermostat learns what time, day & temperature you like. It even will scan when you are there & turn on or do the opposite when you leave. The best function is that the thermostat can be run from anywhere with wireless. So while I am at work, in the car or on trip, I can alter the heating & cooling settings. I never have to come home to a cold house. That is all the enjoyable things I should get with our smart thermostat. Well, I do end up coming home to a hot or cold house. The reason is that our internet is spotty at best. So the thermostat then is not affixed to wireless & therefore not running. It forgets our annually Heating, Ventilation, & A/C program & hardly alerts myself and others about inferior hot & cold temperatures. Basically I can use our thermostat when I am at work. The job wireless is way more reliable. I can set the temperature & hope it does not get messed up when I get home. On the weekends I just manually adjust it love it is a normal dial thermostat.
