Aqara TVOC ZHAAirQuality data

Looks like you already figured out what I was trying to do (add ability to set units in Z2M), but could you shed light on how to get the network key?

I just can’t capture any key exchanges when pairing a TVOC with a M2 hub, but pairing the same TVOC with Z2M I can capture key exchanges.

Help appreciated.
