Silicon Labs' official GUI tool (in Simplicity Studio) that captures RF communication on a Z-Wave network for debugging, the vendor sniffer. Decodes the full Z-Wave frame including command classes and shows security (S0/S2) handshakes. Needs a USB Z-Wave adapter flashed with Zniffer firmware (e.g. a UZB stick). The turnkey capture path when an SDR demod is too fiddly.
Lifecycle not assessed: nobody has checked yet whether this tool is still maintained, sold or working. Check the project's own page before relying on it.
