DCH-Z510 turns on without any reason

Hello guys, do you have any idea, why my DCH-Z510 gets activated without any reason. The siren is connected to DCH-G020, and everything is configured and works as expected, but in the last few months I’ve noticed that the siren turns on randomly ~ once a mount without any logical reason ?
Usually in the app I’ve no “Actions” activated, only when I’m traveling for more than 3-4 days, so it’s not the reason for sure.
This thing creates me a huge stress, because it gets activated at any time of the day. The last time was 2:00 AM.
The next time this happens, I’ll throw it away and write bad feedback to dLink and there “great” product !

When the alarm sounds do you have anythin in the logs?
It would normally show you what triggered it

Where I can find the log files ?
