I live in a hot climate, so it’s really the expense of air conditioning.

Small adjustments to the temperature based on whether or not we’re home, pre-cooling versus cooling during the heat of the day, etc. makes a big difference on the bill potentially.

I’ve seen some scenarios where people were able to save hundreds of dollars a year just by adjusting the timing of systems. The price of electricity can go up and down during the day.

Maybe those cases are outliers and it’s actually not worthwhile, but it seems compelling. If I can put a system in place for under $100, that will be at least as good as what I have and possibly a significant improvement, I’m interested in trying it.

So which was the easiest?

Thanks for the tip! Others have mentioned that it’s very tricky to find one that works offline without the manufacturer’s software (website, login, data collection, etc)

Wow, very detailed! Thanks
