Batteries in a smart thermostat?

I have about an hour of work left to do online but I am so tired already that I think I may need to take a nap before I tackle the rest of my work.

I don’t have anything going on until 4pm when I go train a client on the beach, so I think a nice little nap is in order so that I have energy to get through the day. I was drumming last night and singing for about two hours, and today I am kind of tired, but we did record some good new songs. My smart thermostat stopped working for some reason last night and I was wondering if maybe they had some kind of batteries inside, but the HVAC tech who installed it said nothing about batteries in the thing. I guess it could be something else, but I may just call the lady and see what she says about this model. It is a new wifi programmable thermostat that I bought at the heating and cooling business and I don’t think they would put batteries in these things nowadays. But you never know, so it would be a good idea to give them a call and see what they have to say about it. I could walk down to the HVAC company, as it is only about a five minute walk from the local business where I live in the back. I will take this nap first and then when I get up I will decide if I want to call them or bravely walk down to the place.
