Smart home system recommendation for beginners

When I say bathroom "Alexa turn on the light", the light in the bathroom should also turn on...

"Alexa, do what I tell you, damn it", "Alexa! - the OTHER one on the left!" *LOL*

This is a new aspect for the discussion in another thread about whether there should be a door between the kitchen and the living area

Just a dumb question: what actually happens with such an app from a service provider with whom you are currently having problems and whose customer account is locked - do the roller shutters then stay down so long and you sit in the dark, even though the electricity bill itself is undisputedly paid, but without a light switch the electricity is useless?

Wrong. Homematic also works wired and if Homematic then I also recommend wired! I have already expressed myself positively about Homematic several times here. I actually decided on KNX (not more expensive).. but whatever. I have tried a lot with Homematic... but then wired.

If it's already wired, then I wouldn't rely on Homematic either, but would recommend KNX instead. Because it feels like there is no more development for Homematic wired. Only the wireless solution is inexpensive. I see the advantage of Homematic in the combination of wired and wireless. Thanks to the new Homematic IP devices, the selection is still developing strongly.
