Prtially implements #112 though it is not a stand-alone tool.

[puddly]

The energy scanning API is expected to return a number between 0 and 255, with 0 being "low" and 255 being "high". This is to make values comparable across radios, since all others return a number 0-255.

In bellows, I implemented it like so: https://github.com/zigpy/bellows/blob/58f8a8079a6fa1d25fe536e5d9e3fcfcbf41389c/bellows/zigbee/util.py#L105-L132. RSSI_MIN and RSSI_MAX can be found above. I generated the test tones with bellows as well: bellows --baudrate 115200 -d /dev/serial/by-id/... tone -c 15 -p 20

[Shulyaka]

Thanks! Will update the code.

Fixed. Using the same formula for compatibility (i.e. compare values between radios)
