While experimenting with the Vera Secure Siren in scenes, it seems that you can manipulate the status of the siren, effectively turning it on or off, BUT with a caveat. My scene to turn off the Siren is a very basic setup, setting the siren to OFF with no triggers, timers or schedules. One would THINK that running this scene while the siren is OFF would do nothing, but that is not the case. The Siren comes ON for a brief period (about 2-3 seconds) then goes OFF.
My original plan was to build several scenes to 'Auto OFF' a triggered event, a 'Test Siren' scene and a simple 'Siren OFF' scene. The 'Auto OFF' scene does not work as anticipated at all, in effect setting up a continuous loop of ON/OFF. I believe that the 2-3 second ON effect is triggering the scene to start again, where it waits 30 seconds then turns the Siren OFF - thus resetting the loop.
Has anyone found a better way to interact with the siren, or is there something else possibly at play here, such as Home Modes?
