Can confirm. I’m a tech worker. No smart devices. Laser printer. Very close to going back to a flip phone.
I am looking at some smart locks, but they’re able to be used as dumb locks with PIN code and physical key also. And they have a usb power port on the outside you could plug a battery into.
I’ve gone down the smart home route a decade ago and only did non-cloud integrated devices with physical controls also. But it’s a part time hobby to maintain it.
Ha yeah. I would absolutely confirm there is no data connection
