You do need to know the number, IF you want to maximize the amount of cooling via open window vs AC.

That aside I'm pretty sure this is an "agree to disagree" situation, mostly because it's clear we have different tastes. A smart home for me has the value of letting me control everything in a single place (always on me), without going around looking for remotes that might need a new battery. Automations are good, but I want to keep control over every little detail.
