If you have same schedule every week, don't go on vacation, your kids don't have breaks, don't have seasons, then 'set and forget' dumb thermostat will work for you without any problems. For the rest of us we need some 'smartness' in our thermostats.
You shouldn't need to change the temperature regardless of those things. My house remains at 68-72F basically all the time. Thermal cycling accelerates aging of materials.
Sounds expensive at the equivalent rate of 38 cents a kilowatt hour that I pay during the day.
Power is cheaper than things failing earlier than they could have due to thermal cycling.

Isn't the thermal cycling greater outdoor than indoor because of the differences in the outdoor temperature between day and night? So most ordinary materials indoors should be fine with a delta of even 10 Kelvins/10 Celsius/18 F.
All of the material thermal failures I can think of come from localized and more extreme sources: electronics, lightbulbs, washing/drying clothes, washing dishes in a dishwasher. Water below freezing point too, but that's because the temperature fell below a threshold. None of these are from heating or cooling rooms directly with HVAC.
Yes, it's MUCH worse outdoors, but indoor temperature (and humidity) swings are not good either. I guess most people here just haven't paid enough attention to it as it's a very long-term effect, but definitely noticeable.
Everyone I know offline keeps their house at a constant temperature year-round, yet apparently it's controversial enough to be a downvoted opinion here? WTF?
How about sleep? Ideal temperature is 18C.
That is 64F. Not everyone considers that an ideal temperature.
