Depends on the speed of the motion sensor … In my house I have very fast motion sensors (wired to DSC alarm).
The repeat would allow the the motion to be extended to 2:00 past the last motion, not the first motion.
Many of the battery powered Z-Wave motion sensors will trigger a motion, and then indicate motion for 5 minutes … even if there is no motion.
Also if there is continuous motion … it will not send an update to Vera until all motion has stopped for what ever period is defined for the sensor.
For Battery powered Z-Wave devices I do not recommend turning lights off based on a fixed time from when motion starts … I recommend that you turn off lights when the motion sensor indicates NO motion. And if the default time of 5 minutes is to long … than change the motion sensor timeout. (i.e. the timeout is in the motion sensor and not the AUTOOFF condition in PLEG.
