I live in France and we have the same shutters (metal plates rolling vertically with th esmall holes that can be uncovered).

I automate what I can at home - the CHO (Chief Home Officer - my wife) mostly disapproves because of some weird concerns about reliability (70% of availability for lights is that I call great, but opinions vary).

There is a simple solution for the shutters - you can use a Shelly 2.5 (https://shelly.cloud/products/shelly-25-smart-home-automatio...) that you connect in parallel to the shutter. It works wonders if you have a manual switch on the wall and probably with a remote too (I specifically asked for a manual switch on the wall). You can program the device itself to open the shutters at, say, 10 minutes before sunrise or whatever. You can easily remove them when you leave your flat and reuse somewhere else.

The Real Solution For Real Hackers (c) is to use Home Assistant (https://www.home-assistant.io/). <flamewar on> Do not settle for inferior systems such as jeedom, domoticz, ... </flame war off please do not hunt me>
