I’ve been working on issues with the developers for zigpy/deconz and needed a ZigBee sniffer. Having a spare Pi and a spare HUSBZB-1 I decided to make one. All the information is on the internet only it is bit’s and pieces all over.
I created the attached document to give easy to follow instructions step by step on how to build one using a RPi. There may be better ways but this was simple and it works.

This document is a wealth of information as well, you will need it.
