Need stronger alarm sound on Sonoff Bridge Pro

The alarm feature is great but even set at max volume, it is really weak.
I need to be able to use the Alarm in the conditions of the scenes. This will allow to use a real siren

It would be an interesting solution to introduce the function of a voltage-free relay alarm output and an alarm input reacting to a short circuit to the ZBBridge…

Meanwhile, You can create scene to control siren
