As it is not possible to buy a Z-Wave Zniffer without buying an entire Development Kit, is it possible to convert a UZB Controller into a Z-Wave Zniffer?
To convert a UZB Controller to a Zniffer, use the firmware image “sniffer_ZW050x_USBVCP.hex”, available with the Zniffer download, and proceed as described in the UZB programming guide.
Be aware that the white controller UZBs have SAW filters mounted, while the black UZBs Zniffers have not. This means that a white UZB can only be used as a Zniffer for the regions specified on its exterior.
NB: Please note that this approach only applies to Sigma Design / Silabs branded UZBs. Other manufactures might have used other chips in their USB Controllers.
