When creating a sensor on a construction site, it is possible to adjust the Mute mode so as not to trigger an alert on certain types of sound all the time. Muted alerts are raised but appear "declared" in the dashboard and no notifications are sent.
To do this, it is necessary to mute the sensor at the level of the types of measurements and allow to put it or not for each type of nuisance. In the editing the interface of a sensor, on each line of type of Measure, there is a column "Mully" after "Ratio". A list is added and allows you to tick all the types of nuisances managed by this type of measure.
Example: Mute the Siren on a 'B' sensor (No notification and status 'Declared') and keep a sound sensor without mute 'A', for all users of my site. On the same site, alarms raised by sensor A are "To be treated" and alarms raised by sensor B are "Declared".
