Smart thermostats are nice and all that, but the single thing that I do not adore about them is the fact that they are controlled mostly through an app on your cell phone, then I ran into an issue recently with this when our password to the app would not work! I had changed nothing, but this was a software failure all together; during this time I could not control our central heating and A/C idea unit other than using the thermostat by hand.
This totally defeats the purpose of a smart thermostat.
I had to call the local heating and cooling supplier and tell them what was going on and then they had to get hold of technical support of the thermostat corporation. It was a real mess to say the least; after this happened I decided that I was going to switch back to a typical digital thermostat. At least with a digital thermostat I think about what I am getting into and there are no laptop programs involved. I can simply run our central heating and A/C idea unit as needed using the typical digital thermostat adored before the invention of the smart thermostat. I will miss saving a few extra bucks on our yearly energy bills and I will miss being able to program the smart thermostat and all that nice stuff; but this is a small sacrifice to make just to be able to have our central heating and A/C be simple and simple as it once was beforehand.
