Jablotron Turris dongle

I’d like to use Jablotron Turris dongle for teaching purposes - has anyone already created any simple project I can use for teaching/motivation? I mean sort of set up/how to for beginers locked at home now. No need for any ‘meaningful’ functionality, anything like starting a siren will do.
thanks!

(preferrably without Turris itself, I only have a few of those dongles)

Hi where did you get one dongle?#
