Motion sensor loses status

I have two everspring PIR motiondetectors. They were integrated and working fine.

Today, suddenly, one of them stopped to work. I still can poll it, but it doesn’t show any detection. It stays red in Vera (like motion is detected).

I excluded and included it again, but no luck.

I read the topics and found out that it happens more often, but I didn’t find a solution.

Anybody an idea? I do not work inside telnet or in the Linux environment, so I need a laymen’s solution.

Battery issue?

No, batterijen are new. Strange thing is, a i told before, I can poll it. Also the battery status is showing.
