problem with volume slider for Denon Ceol piccolo

Designer 2.5
1

Hi all,

I want to add a volume slider for the Denon receiver to my panel.

What I already created is:

a set volume command
a get volume status command
a volume sensor using the get status command
a volume slider using the set volume command

The problem: when starting the panel the volume level is shown correctly and when changing volume level with original remote control the slider is updated correctly.
But when I want to change the volume level with the slider nothing happens.

The set volume command is a HTTP-command:

http://192.168.1.6/goform/formiPhoneAppVolume.xml?1+${param} Method: GET

I hope someone can help me.

Thanks in advance

Dieter

So far I find out that there must be a difference between setting volume via browser:

http://192.168.1.6/goform/formiPhoneAppVolume.xml?1+-69 (it works fine)

and setting it via my slider command:

http://192.168.1.6/goform/formiPhoneAppVolume.xml?1+-${param} (it don’t work)

hoping to get some help

Dieter
