Or they do switch but for like 1 day and then go back to messaging you on WhatsApp. I tried switching to signal at least a couple times, even convinced a couple groups to move, but not a single chat lasted more than a couple weeks. Eventually they all went back to WhatsApp. Every single one. It’s extremely difficult to get people to care.

You can have devices on your wifi network without giving them access to the internet. You set your firewall (which, for most people, is the router that comes with the internet subscription) to block all internet traffic to and from those devices while still allowing them to communicate with the other devices on the same local network. Fairly straightforward on most routers with a little bit of time spent looking up the basics.
