My Multisensor 6 paired really quick and it does see the motion but not from any distance. I have it mounted in my ceiling (10’) and it will detect motion only from a very limited distance. I have tried to set the sensitivity from max to min but still the same. I have rotated it a full 360 and it will see somewhat further in one direction but not too far. Also the temp and humidity sensor aren’t very accurate. Is there any way to “adjust” it?
What DTH are you using? There are options in the device to modify the sensitivity of the motion sensing. Here’s one if you’re looking:
