Coolcam NAS-DS01Z doorsensor out of range?

[ivom74]

Hello
I have for the first time a range problem. I use a Aeotec z-stick and a couple of fibaro switches.
I now bought a coolcam doorsensor which works fine if the Aeotec zstick is not to far away.

I already tryed a Fibaro switch besides the Coolcam. The Fibaro works 100% fine. The coolcam doorsensor don't.

Is this just a problem beause of the cheap Coolcam stuff which looks likes the problem here?
Is there a way to let Coolcam use the Fibaro switch as extender?
