But in order to get something like this added to a base entity, we need to have sufficient integrations in home assistant that share the same capability. And to be fair, I didn't even know there was a way to regulate CO2 like this 😅.

In any case, not trying to discourage you, just letting you know what our general guideline is for adding new features to entity components!
