In case you are still using Bose SoundTouch speakers with Home Assistant, I have developed a custom component called SoundTouchPlus that breathes new life into the SoundTouch support. Here’s some more information in another thread on the details if you want to check it out.
Check out the GitHub project wiki for more detailed information and installation instructions (easy HACS install).
Hope it helps!
