I know some people with privacy concerns will go out of their way to avoid any “smart” devices that communicate over WiFi. If you stick with Z-Wave/ZigBee/Matter, you don’t have to worry about any sort of external communications. I mean, even with WiFi devices you can isolate them by making a separate local-only network, but that’s a pain.

I imagine they are looking for a solution that you can self-host. Notion is great but you can’t host it on your own hardware.
