I live in a big city in the center. When i activate “Show bluetooth devices without names” in the developer settings of my android 13 phone, there appear loads of this devices. I have no clue what they are. Does anyone know? Are that the bluetooth nanobots of the vaxxinated people? (/s to last question!)
I have replaced almost every light bulb in my house with smart bulbs which feature both bluetooth and zigbee connections. It’s around 40 devices. If your neighbour has smart bulbs or other devices, I guess that could be a large part of it.
Started with smart bulbs, but very quickly moved to actual smart switches+plugs instead.
Smart bulbs automatically turn on when power goes out and back on. (so you can still control them from the regular switch) This is anoying af with how frequently I get short power outages.
My wife and I used to have some smart switches in a previous house that were set to turn on when we came home. Woke the kids up a few times forgetting to turn that off before coming back from a night out.
