We just finished a replacement of a 40 year old gas furnace for our basement and first floor. Our second floor has separate heating and cooling, only about 10 years old. My wife and I remodelled the 120 year old "worker's cottage" ( ) style home in the mid 1990's. We kept our original furnace at the time. in 2001 we hired a crew to dormer the roof and finish the second floor (we had more money at this time and didn't have to do the work ourselves). At that time we installed separate heating and cooling in the second floor. We used a programmable, but non-connected thermostat.

Just this summer we replaced the old furnace for the first floor and basement. The furnace dated from the late 1970's and was not too efficient. We had central air added as well, along with some duct work changes.

I worked with the HVAC contractor to choose the best thermostat. We looked at all the options and the clear choice was a standard programmable thermostat. The benefits of a smart, connected thermostat were negligible. Once programmed, the standard thermostat adjusts and maintains the temperature perfectly on your schedule. It works well, costs less and is not vulnerable to cyber-attacks.

The benefits of a connected thermostat are few compared to a programmable, but the cost is much greater. Not really worth it.

As for thermostat settings, I prefer the simplest option: a single fixed temperature that the system maintains +/- a degree or two.

The house itself should be efficient and have enough thermal mass to prevent large temperature fluctuations throughout the day anyway. If you feel the need to "adjust" the heat/cooling at different times of the day, perhaps you should invest in more insulation or higher efficiency windows instead of a fancy internet connected thermostat.

I'm partly with you. I live in Canada and I have programmable thermostats. In the winter there's no reason to have the house at a human comfortable temperature all the time. The thermostats are set to 62 deg in the winter. We suffer the cold in the morning because we're only in the house long enough to have breakfast then we're out the door for the day, but the thermostats all kick in about 30 minutes before we get home to heat the house to 70 deg. Then they shut off about an hour before bed.

The reason this works well for us is because my wife loves to crank the heat to 75 degs, then never remembers to turn it off, which has costs us a fortune in the past. With the programmables she can still occasionally crank the heat, but the thermostat always readjusts automatically when the next trigger time kicks in. They're also easy enough to set to a constant temperature if we're going on vacation and then we can just hit the "run" button to put them back on their regular schedule when we get back.

Where I agree with you is, it's just a convenience. We could survive perfectly fine with the analog mercury thermostat. These are just easier so we don't always have to remember if they're on or off and the house is warm when we get home in the winter. In the summer I just flip the switches and turn them off altogether.
