Alarm trigger with ACT ZIR010

Hello together,

Has someone of you figured out how to make Vera sense if the housing of a ACT ZIR010 (ZIR000) motion sensor has been opened?
The manual tells, that it sends out a ON command to devices associated to group 2, but I don’t know how to let Vera recognize it?
Vera automatically recognizes, if the sensor gets tripped (which is send devices in group 1) and it also gets the battery state (which is send out to devices in group 3).

I haven’t associated a single device to the sensor, because I want Vera to handle those events.
So Vera catches the group 1 events (tripped) and the group 3 events (battery level) but what about group 2?

Hopefully I could explain detailed enough where I’m coming from.

best regards,
