Well, I personally can't answer the question about free@home for you.
But it has already been asked and answered many times on the internet.
Of course, the answers are very individual because everyone has different expectations.
Your expectations regarding "Smart" home seem rather low to me.
Therefore, free@home could be an alternative.
Personally, I would never rely on just one provider for something like that, but either follow a standard or stick to classic electrical installations. Then maybe add a simple roller shutter control and that's it. Lights via Hue and that's fine.
Just to be able to tell friends you have a smart home but in the end can only control roller shutters wouldn't be worth it to me.
It was all discussed back in January…
Oh, good point.
If no new knowledge has come up since then, I would advise against it again and just install a roller shutter control + possibly Hues.
That's it.
