Sure, if you have a bunch of time on your hands, are into integrals and heat transfer equations, and really enjoy analyzing large volumes of data.

The problem with programmable thermostats is that few people know or have the time to program them for optimal energy use. Resideo Energy Care knows and will do it every day with unmatched precision. Not only does Energy Care optimize thermostat settings each day, it also recalculates settings on-the-fly if the weather develops differently than forecasted!
