HTTP API increase volume steps (1 Viewer)

[tommi32]

Hi there!

Im a owner of Yamaha AVR HTR-4072.
I need help with control the receiver with HTTP API commands.
I want to increase the volume with bigger steps as 0.5
If a send this command:
wget 192.168.1.113/YamahaExtendedControl/v1/main/setVolume?volume=up&step=2 or
wget 192.168.1.113/YamahaExtendedControl/v1/main/setVolume?volume=up&step=2.0 or
wget 192.168.1.113/YamahaExtendedControl/v1/main/setVolume?volume=up&step=1
the receiver still increase only + 0.5.

can someone take me a hint, where is the problem?
For info, here is the output of http://192.168.1.133/YamahaExtendedControl/v1/system/getFeatures

Tommi,

Have you updated your Yamaha to the latest firmware? It does matter what version of API you are using. You should be able to query that with the following:

Here is the Yamaha documentation for volume on V1.17+. Which automation/control system are you using? It might be necessary to pass json response to call a volume increase.
