@th-zuberer My twists finally arrived today and I just had the same experience of disappointment on this - I bought this expecting to be able to initiate playing music or audible on my sheds and control the volume :0(
I hadn’t seen this post but already gone through the process of creating 4 routines that set the volume to my 4 most common numbers on the relevant Alexa device. It gets the job done I guess - but it’s pretty sucky and 100% not what I expected, especially after waiting 18 months longer than originally planned…
