There is 6 parameters i can set, 3 for alarm and 3 for doorbell (duration, volume and music), but i can trigger only the alarm part of the siren.
I tried the Notification Command Class (https://www.vesternet.com/resources/application-notes/apnt-125) but without success.
If i want to switch to doorbell i have to change the alarm sound to a doorbell sound then trigger the alarm, then switch back the alarm sound.
There is a way to trigger the alarm and the doorbell separately without changing the alarm music ?
Yes you can do this using a http command to change the parameter value.
I’ve used PLEG and multiswitch before to do this but it does is not an instantaneous result as the the Siren is a frequently listening device (FLIRS), so there will be a time delay.
In the end I found it was easier to add additional sirens, each with there own parameter.
