3 years ago FYI, zigpy-znp can do Zigbee channels energy scans https://github.com/zha-ng/zigpy-znp
https://github.com/zha-ng/zigpy-znp/blob/dev/README.md
Energy scan
Perform an energy scan to find a quiet Zigbee channel:
$ python -m zigpy_znp.tools.energy_scan /dev/cu.usbmodem14101
Channel energy (mean of 1 / 5):
------------------------------------------------
+ Lower energy is better
+ Active Zigbee networks on a channel may still cause congestion
+ Using 26 in the USA may have lower TX power due to FCC regulations
+ Zigbee channels 15, 20, 25 fall between WiFi channels 1, 6, 11
+ Some Zigbee devices only join networks on channels 11, 13, 15, 20, or 25

Make use of Energy Scan to allow the user to find a better channel before setting up z2m add-on.
This could potentially be added to z2m add-on to choose a good channel on 1st boot.
