Xiaomi gateway play stream radio mp3

hi, its is possible to play any sound (radio stream, url, mp3) on gateway when motion is detected?

For sure You can play some radio streams (chinese) through the Xia app. Additionally You can play sound which are built-in through Hassio, or nod-red.

According to the radio streams:
Maybe You can redirect “Cast” address and create some stream locally… (just an idea).
