Alarmo siren duration

Hi,

Since Hive turned off their alarm system this week we have had to go DIY, we have everything working fine except the siren that will only sound for 5 seconds.

We have it setup to sound until it is disarmed but it will only sound for 5 seconds and stop, but Alarmo still shows the state as Triggered.

I wonder if the Hive Siren is just a 5 second sound that it would play on a loop but Alarmo doesnt know to play it as a loop?

Here are the events, nothing seems to tell it to stop sounding.

Any advice appreciated, does anyone else have a working Hive alarm locally?
