Z-wave range of only centimeters

i am experiencing the same problems from the beginning on. However only with the expensive Fibaro multisensors. The cheap neo coolcam pir never gave me any troubles and also the door/window sensors from coolcam work perfectly. The only problem items are the battery powered fibaro’s. The normal fibaro’s such as the binairi sensors works also flawless. In your case i would try a coolcam pir once . Upcoming friday they sell them even cheaper (18 euro’s) at ali.
