Flood of false detections (neo coolcam PIR)

Configuration Z-Wave
1

At random times one of my Coolcam Zwave PIR sensors gives a lot of false motion detections. As you can see in the history diagram there are a few brown (green/red) bars where there are a lot of state changes. I am very sure there was not something that could trigger the sensor.

Below you can find the first and last part of the surrounded part (09:41 - 10:11). Does anyone have an idea what can cause these detections and how I can fix this?

Second question, can anyone explain how I can interpret the received data from the log? So what means “Received: 0x01, 0x0a, 0x00, 0x04” for example

thanks in advance

I tried to exclude, reset to factory settings and include. After two days the problem went back :frowning:

I looked again to the log and it noticed that the sensor sent a SensorBinary report (state=on) within a second after a SensorBinary report (state=off) is sent. This is strange since the retriggerinterval is set to 8 sec.

Someone had an idea what causes this problem?

I had something similar and replaced the battery. Not sure if it was that or the case of just “turning it off and on” but not happened since

I will try that tonight, thanks for the suggestion!

Changing the battery solved my issue. thanks!
