It’s important for devices to have internet connectivity so the manufacturer can patch remote exploits.

[A store salesman, Hairy, is showing Cueball a dehumidifier, with a “SALE” label on it. Several other unidentified devices, possibly other dehumidifier models, are shown in the store as well.]
Salesman: This dehumidifier model features built-in WiFi for remote updates.
Cueball: Great! That will be really useful if they discover a new kind of water.

ZigBee is Bluetooth, so controls can be done entirely locally.
We have Aqara (ZigBee) water leak detectors for our sink and basement, a 3rd party USB ZigBee dongle and a raspberry pi running home assistant. This gives me a discount on our home insurance that is more than the devices. Everything runs only locally.
(Admittedly I am not including the cost of the pi, but you could salvage an old laptop or something instead. My pi has other things on it other than HA, its multipurpose)
I also have some WiFi RGB bulbs/led. Using home assistant I can swap their colors for the holidays and I never have to decorate again. I’m lazy, and I hate Christmas.
