Fibaro Motion Sensor is activated alone

[Solventus]

Hello, I have a Fibaro Motion Sensor in Domoticz.
At night, when there is nobody in the office the sensor is activated. I don't know why this happens.
Can you help me with that?

Thanks a lot.

Maybe a spider walked over it

I had similar effects in my kitchen with the same sensor. It seemed to be reacting to the temperature changes caused by the refrigerator or possibly other appliances. So I adjusted the sensitivity just a small amount and relocated the sensor. All good now. Do you have any intermittant heat sources in your office?

Hello StandHD, thanks a lot for your reply.
About sensitivity, Are you referring to parameter 1?
In this parameter I have a value of 10. What value do you have?
I haven't any intermittent heat source, but at night the temperature might be higher than during the day. Could that be a problem?

Yes I set parameter 1 to 15 which fixed the problem but of course made the sensor less responsive to real motion. After relocation I set it back to 12 and it seems to be ok for the last 6 months. So try adjusting it first, and if you have no luck it may be worth relocating. I still had the same area covered just from a different angle by placing in the opposite corner of the room.

Hello everybody.
I have a new problem with fgms-001 fibaro motion sensor.
I install a new raspberry + razberry. When I include a FGMS-001 (3 units) then it show the next image.
The ID 600-700-800 are the FGMS.
I don't know why the fgms are always on.
Thanks
