I have a pretty robust home assistant system running on my own home server at this point and I’m pretty satisfied, except that I have to very long USB adapter cables running up the wall to position the zigbee and zwave dongles where they get the best reception.
I would like a cleaner install, so I wonder if there’s anything out there that looks sort of like a smoke alarm (like this) that I can stick somewhere on the ceiling of my living room and then connect to my home server, preferably wirelessly but ethernet would be ok too - usb would be unpractical but I don’t know if such a device even exist.
