Touch screen with multiple locations to play a sound (doorbell)

For our office, I’d like to install a touchscreen in the lobby. It will display the names of 8 companies, and when someone clicks on a name, a sound should play in that department. Does anyone have any idea how I can send the command from the touchscreen to Homey? From Homey, I can then address the relevant speaker or similar device to play the sound. Thanks in advance!

Sounds like an application for ‘Fully kiosk browser’:

and the Homey ‘Dashboard controller’ app:

That allows you to setup a cheap tablet (I use a Fire HD) with a simple HTML/Javascript page that invokes Homey flows - and to lock it down.
