...anticipate the time it takes to reach a certain temperature by a
certain
time?

For example, during the day while no one is home but the cats, we keep the
temperature set at 80°F. I arrive home at 5:00 p.m. and would like to
have
the temperature at 75°F. when I arrive.

Rather than my having to "guess" how long it might take to reduce the
temperature by 5 degrees, is there a thermostat capable of figuring that
out?

TIA

I had two programmable thermostats removed, and cheepos put in their place.
Unless you are homebound and have the exact same schedule week to week,
there is always times when the units are running and no one's home, or it's
too hot or too cold. Saved a lot of money. We live in hell. Couple of
days ago, it was 113. We leave the windows open during the day, as leaving
on the AC is just a waste. From the time we get home, it takes only about
fifteen minutes to cool down the house. Then at about ten, we open it up
again, as the night time temps are very cool. I don't think fifteen minutes
is a long time to wait, when given the choice of $$$$$ more each month.
