I bought two of the Fibaro FGMS-001 sensors off of Amazon specifically because they were supposed to be compatible with my Homeseer HS3 system.. but as with almost everything else... not really. While they can be added to the Z-Wave network, the actual sensors never return anything.
I have changed parameters... added and re-added the sensor.. done multiple scans. Nothing. My experience with Homeseer and Z-Wave in general has been very, very frustrating.
