Found wifi thermostat

My hubby entirely tries his best to install current things for the current home and do little repairs and renovations. He does a good task, not the best, and has made some mistakes here and there but he gets the task done…eventually. I guess it takes him a while to get the concept down and to figure certain things out because it literally took him almost a day to try to change an air filter. At first he couldn’t figure out where heating and cooling air filter was located. He had to call his brother who is a local heating and cooling serviceman on where it was located and what kind of filter he needed! Little did he think that the size of the air filter is the a single that is already currently in the heating and cooling system. I remember him getting off the iPhone with his brother and he was so embarrassed. I kind of felt bad for him because he tries to live up to his brothers knowledge on repairs and renovations. However Last month my hubby went to the store and he found a smart wi-fi thermostat on sale. I have constantly wanted a single of those and he surprised me with it and he installed it. I was really impressed by this and I didn’t ask him if he asked his brother for help, I really wanted to show him how gleeful I was. He went through the current thermostat with me and showed me all the additional features. He showed the strange notifications on how it’ll notify us when all of us may need to have our heating and cooling system service and cleaned. He also showed me the app that would allow us to control the temperature in our current home from somewhere as long as all of us had repair on our iPhone. I was really gleeful and impressed that our hubby bought and installed the smart wi-fi thermostat!
