Hello, KlausRoessler,
Please clarify whether you want to send such commands from the application or to receive a notification when a parameter is changed?
If you mean a notification about a parameter change, please specify the names of the parameters coming from the device, we will check it additionally. You can find these parameters in the Toolbox of your unit by looking at the messages.
More info about Toolbox you can find by the link. – https://help.gurtam.space/en/7af597c9-e302-4e55-a66d-9e9f97c67d93
