[Question] fan speed
@lprhodes First of all thanks for your work and sharing this great and helpful plugin.
I'm relatively new to homebridge but thanks to the good documentation of this plugin I was able to configure it and adding my fan. 
The fan (Balmuda GreenFan Cirq), has three buttons on the original remote. Up, Down and Power toggle. No swing option, so I just removed the line in the config.json

But because of only four possible speeds of the fan I set up 10-50% to (-) and 60-100% to (+) hex. Any more elegant suggestion on this? Four LED on top of the fan indicates the speed.

Thanks in advance for your help and reply.
