I have a pretty simple smart thermostat without many fancy features. Every Spring and Fall I tell myself I should set up some kind of system where if the outdoor weather is good enough, maybe I dial back the heating / cooling, maybe send myself a text to open windows, etc.
Small example: I normally keep my house at 72 in the summer, but if it’s up to 76 or so outside, it’d be nice if the thermostat turned off the cooling. I could manually turn it back on if I have guests over, etc.
I’m sure some of this logic would be easy to code myself, but wanted to check out what anyone else is doing first.

I have the same sensors, but on many windows. If I have windows on either side of the house open simultaneously and there is a favorable temp difference outside vs inside, an automation turns on an air exchange fan. If they are closed, I use advanced heating control
