This is why I prefer standalone smart furniture and gadgets. All stuff that doesn’t need to be built in the house, but can be updated and swapped at need. Also, every time I ask myself really hard if I need this thing or just want it.
What a house should have in any case, is a good network and Ethernet plugs in every room. This makes the addition of new gadgets much easier I found. I must admit I’ve not gone the WiFi mesh route, but it looks interesting as well. Guess I’m just old school on that.
