Track real-world device status with an RF Receiver 
Hi,
thank you for your great job in this project! 

I have a feature idea for the window covering part. I have a little problem with the architecture, because if I want to use the original RF remote controller, the % status of the blind doesn't updated. It will be possible to listen to the RF signal of the original remote control and update the blind status. 

The best will be, if the broadlink device can listen to the RF signal. 

If it's not possible there is a cheap RF receiver for Rasperry Pi and a [homebridge plugin](https://github.com/topas/homebridge-rfbuttons). With this solution I can listen to the original remote rf signals and I can make rule in the home app that triggers the right (open, close, stop) switch, which is coupled to the blind accessory in your plugin. (For this I need switches (up, down, stop) which is coupled to the original blind accessory.)

Better solution if you can integrate the whole RF listening part in the plugin and we just have connect the RF receiver to the Raspberry Pi and we don't have to create a rule in the home app.

If it works than it can extended to the other accessories. 

I hope that it's possible and you can make it! It will be a real smart home solution!
