The system environment does have radio based components - but you are right, some things cannot be achieved without deep integration with the house. But yeah, I rented for a long time and while I used radio based systems it is not as good. My hope is that it does get common enough that more and more landlords adopt it,at least for the midrange segment. We do actually provide some limited integration for a small apartment we rent out but currently it’s not something people care about tbh and the law here is a bit problematic in that regard, but that’s a very local problem.
