RM Pro seems can not be recognized....
I am using Raspberry + Homebridge to enable the Homekit function, so far, most of devices have been enabled. 
Just the Broadlink is on testing... 

After installing the plug-in, from the log files, it shows:
[Info] We've discovered an unknown Broadlink device. This likely won't cause any issues.

Please raise an issue in the GitHub repository (https://github.com/lprhodes/homebridge-broadlink-rm/issues) with details of the type of device and its device type code: "4e68". The device is connected to your network with the IP address "192.168.31.218".
