That is helpful. Thank you. For some reason I thought I would need to sniff the traffic off the same USB device that is on home assistant. If I can sniff it off the air on another regular Linux PC I just ordered another dongle.
What I am trying to achieve is to figure out what battery information send end devices. I am new to HA trying to decide between ZHA and Z2M but both give me some weird battery readings on couple of devices I moved off Smartthings for testing.
