I’m assuming when you say you can control the Bose manually via the app you mean the ST App?
If this is the case, depending on how the Bose device handler (in the ST IDE) is designed, you should be able to call on the different features using CoRE.
You can setup a CoRE Piston to trigger when a routine executes.
In actions, select your Bose device and then you may see custom commands for the device indicated with little triangles.
Worth a try!!
