MMM-PIR-Sensor - Delay

[pauabaer]

Hi guys,
i installed the PIR-Sensor module and it is working. I am using the default configs. But i have noticed a undefined delay. Sometimes it lasts up to 30 seconds to turn on the display. Other time it was only 15 seconds.
Actually the monitor should be turned on again without a delay.

What can I do? Do you have any hint for me?
