I deleted this question, after it was downvoted and closed as off-topic***.
However, for me to improve I need to understand why. Based on the close message and linked documentation it sounded right on topic to me (it's about how to use software to control hardware... no?).
I noticed that there were no tags for Alexa, Echo, Google Home, etc. Is it just that these voice controlled devices are kind of unofficially off-topic? It seemed that way to me, but I'm guessing that's not the real answer and there's something I can learn here to be a better SuperUser user.
Thanks! Wasn't sure if the best tag for this is "discussion" or "support" so I added both - please feel free to edit.
*** for anyone who can't see the text of the deleted question I linked to, it was basically this:*
I have an Android phone and multiple Echo dots and for some reason the voice recognition on Alexa does not work as well when issuing multi-room music commands... [technical details went here, omitted for brevity]... as a workaround, is there any way to control the music selection without voice for multi-room music? I only know how to do it for one device at a time.
