My goal is to get a volume slider to control the volume of my powernode (and slaves). I have looked into this topic but I can’t get it to work.
What I have done so far is:
I created a volume channel (number) under my existing Bluesound thing. Filled out the
command extension with Volume?level=%2$s (taken from the previous post). After that I created a volume item (dimmer) and linked it to the volume channel.
I am not able to control the volume right now. The slider shows changing volume numbers.
With the command
http://10.10.10.111:11000/Volume?tell_slaves=1&db=2 in my browser I can put the volume louder. With -2 at the end the volume will get softer.
This is the code from the channel.

This is the warning from the frontail viewer.
Requesting 'http://10.10.10.111:11000/' (method='GET', content='null') failed: 404 Not Found
I also used this API document from Bluesound.
At this moment I am stuck and any help is appriciated.
