Alarm sound

[brjhaverkamp]

Hello all,

I am creating a homegrown alarm system with zigbee door contacts and PIR motion sensors.
I have wallpanel as a control panel to switch alarm states (off, alarm home, alarm away)
I now also wanted to use the panel to make an alarm sound.
I currently send wallpanel a mqtt message with:
msg.topic="wallpanel/mywallpanel/command";
msg.payload.volume="100"
msg.payload.audio='http://192.196.xx.xxBurglaralarm.mp3'

This works well. But the mp3 is only a couple of minutes. And at the end the sound stops.
Does anyone have a good idea to either loop it, repeat it or othewise make a continuous alarm sound?
(Till the alarm is disabled of course :-)

Kind regards,

Bert
