Roller shutter smart home retrofit renovation old building

As already mentioned, this was done via Loxone. The possibilities are almost unlimited and the relatively simple way to integrate third-party products (Homematic miele@home etc). I don't think much of these systems that bear the name of well-known companies but somehow have nothing to do with the manufacturer.

All right, thank you very much. I find the overall package quite expensive compared to, for example, the Bosch system, which is more intuitive for me to understand. Maybe there are additional suggestions or answers to the (other) questions :)

It is overkill in this case, but Patricck always recommends it, no matter the requirement :)

It's also like using a sledgehammer to crack a nut in this case, but Patricck always recommends it, no matter the requirement :)

Well, because it's possible and because it works ‍♂️

Okay, you can also do it with KNX or Crestron. However, it is equally unnecessary in this case.

So I will implement exactly the same with the Shellies. They have been around for a while, have devices that work well, a reasonable price-performance ratio, and a corresponding community where you can get help if there are problems. Additionally, in case of emergency, you can install alternative firmware on the hardware.+

Yes, it is wireless (WLAN), so good network coverage in the house is necessary. But today that is planned anyway (e.g., at least one WLAN access point on the ceiling per floor). You can also control via the cloud from outside, but you are not forced to do so (you can disable the cloud function).

I tested the Shellies for over 2 years on the pool pump control in the old house, and it worked completely reliably there, despite relatively poor WLAN coverage in the garden.
