Does anyone know if something like this already exists for the heavy duty, built-in shutters they have in Italy? The kind that close and form a barrier over the window and are operated with a flat roll of fabric from inside.
After you have electric-controlled rollers, you can control them via any automation you want by installing a "Shelly Plus 2PM" device behind each switch.
I connect the Shellys to home assistant, and from there, trigger all the rollers to go down a certain number of minutes after sunset. They all rise at a certain time in the morning. You can always trigger them manually too, of course. ChatGPT can spit out very complex YAML for HA if you want to make life easier, your only limit is your imagination.
