So you would be fine being a guest in someone's else house, no control over anything and just let whatever automations are in place do their thing? But all of this in your own home? Temperature is an important value to know, tells if it's better to turn off the AC/heat and just open the windows at that time, or when it's the better moment to open them and air the place. Same with air quality, if it gets worse with the windows open it's better to close them, or if it's not great inside it might be a good idea to open.
My fan has an app or a pair of buttons on top, no remote.
