I went with a more passive solution. I have a fairly regular schedule, for full disclosure. I just bought a few wifi sensors and placed upstairs and downstairs and monitor it. I then set a schedule on my thermostat to reasonable values and have my remote sensors set to +/- 2 degrees with a pop up alert if they don't meet the schedule that I programmed which is worth noticing. No wifi thermostats, just ones that will probably last 15-30 years. The older I get more I grow tired of squeezing out that last 5% of value for 90% more effort and I appreciate the old ways, turning off lights when I leave a room. Unplugging things when I'm not using them. The one automated thing I do appreciate though is my security and camera system, those have actually proven valuable over time and well worth the effort to self install.
