Open the windows at mid-day to save energy

Blueprints Exchange
1

I don’t know if this is a very specific problem, but I often forget to open my windows during the day. (In Germany air ventilation isn’t very common) Further I wan’t to save on expensive gas by only opening the windows when it’s relatively warm outside.
So I created an automation wich sends a reminder to the person at home to open all the windows. When I interact with the notification it sets a timer and reminds me to close them again.

I would share this as a blueprint but sadly I’m bad with yaml.
Maybe someone could flesh out this idea to include window sensors or the weather forecast

You can buy a linear actuator which can open your windows and then control it with HA. You can also make it do that based on weather and presence, conditions, etc.
