Unable to find Z wave sensor

[thomas-tran]

The Z Wave Controller Aeotec Z-Wave USB Z-Stick GEN 5 is connected to the raspberry pi gateway. The gateway is able to recognize the controller however the gateway is unable to find the Z Wave sensors e.g. the Fibaro Z-Wave Door.

Are the sensors and the dongle operating on the same frequencies? My Gen 5 says ZW090-A (908.42 MHz) on the back (which is correct for North America). The devices should have the frequency printed on the back of them as well. Make sure they both match.

Did you try factory resetting the Fibaro? If it was previously paired with a different dongle then your current dongle won't see it until you factory reset it and pair it with your dongle.

I tried that, reset to factory default both sensor and controller. All of them are in the same frequency. The device are able to detect from OpenHab, however, I use the same set of devices in Mozilla gateway version 0.8.1. Only the controller connected to USB is able to detect, other wireless z waves sensor are unable detect.

I found with the Yale door locks that doing a factory reset didn't "unpair" them. I had to go through the unpairing process on the door lock in order to get it to pair again.

What I discovered is that I needed to have one other device paired (say a power switch). I would initiate the unpairing process on the power switch, which puts the zwave controller into unpair mode. I would then complete the unpairing process on the door lock (i.e. I would never touch the power switch - it was just used to get the controller into unpairing mode).

It turns out that when the controller is un unpairing mode, you can unpair any zwave device, regardless of which controller it was previously paired to.
