You're looking for a pager system? Something like this?

That would be device-dependent. You would need to find a manufacturer and model that supported some type of USB or Bluetooth interface, or possibly an HTTP interface if it was its own webserver (similar to how an ethernet router or webcam works).

I don't know of any specific makes/models as I've never implemented those with our systems. A quick search turned up this: https://www.retekess.com/blog/Do-you-need-API-support-guest-paging-system-for-your-POS-system/ so it looks to be an option for at least some of the units that are available.

These are surprisingly hard to find but if you don't find anything with an interface that your app can connect to, then a Plan B solution might be to note that many of them use 433.92 MHz radios, and so if you acquired these:

and hooked them up to an Arduino-ish board that you can communicate with from your restaurant(?) app via Wifi, then that might get the job done.

(plus it'd be doing double-duty as a software-protection/licencing dongle for your app too - bonus!)

You'd look at the data out line of the receiver when calling a pager, and then later emit that same bitpattern via the transmitter. Akin to a tv/vcr/dvd learning infrared remote control.

The author of the above page seems to have done this, but for controlling wireless power-point switches:

You've got me fired up now I've already got working ESP32s here somewhere and I'm going to buy something like: https://www.ebay.com.au/itm/144858438200 and https://www.ebay.com.au/itm/304188210822 and give it a burl.

I'm trying to find a cheap way of acquiring a pager system to test too. One transmitter and one or two pagers would be enough. Or to borrow, or even just use for an hour. The pharmacy I used to go to had something like that for when prescriptions were ready, I'll poke my head in there next time I'm driving past.

note to self: pager model numbers T115 and T119
