Sleep as Android's Bangle.js wearable integration with Bangle.js 2..?

Hey,

I just got hands-on experience and tried implementing the Sleep as Android integration for Banglejs. It was relatively straightforward, but I still need to figure out how to enable or disable my Bangle app from Gadgetbridge.

My current solution is:

• Create a simple app that provides all relevant measurements for Sleep as Android (Movement, Heart Rate). I've already got this working.
  
• Make it possible to start/stop the app from Gadgetbridge. If you know of a good way to do this, feel free to chime in!
