Smart temperature controls are nice and all that, however the one thing that I do not love about them is the fact that they are controlled mostly through an app on your cell phone! I ran into an issue recently with this when my password to the app would not work! I had changed nothing, this was a software failure all together, then during this time I could not control my central heating and air conditioning unit other than using the temperature control by hand.
This totally defeats the purpose of smart temperature control.
I had to call the local heating and cooling corporation and tell them what was going on and then they had to get hold of technical support for the temperature control business. It was a real mess to say the least! After this happened I decided that I was going to switch back to a familiar digital temperature control. At least with a digital temperature control I guess what I am getting into and there are no computer programs involved. I can simply run my central heating and air conditioning unit as needed using the familiar digital temperature control love it was before the invention of the smart temperature control. I will miss saving a few extra bucks on my daily energy bills and I will miss being able to program the smart temperature control and all that nice stuff, but this is a small sacrifice to make just to be able to have my central heating and air conditioning be as easy and easy as it once was beforehand.
