Hello Victron community,

I’m looking for guidance on how to properly integrate a custom D-Bus service into the Settings menu UI on a Victron Cerbo GX device running gui-v1.

What I’m trying to do:

  • I want to add a new QML page inside the Settings menu, similar to how other devices or services appear under /Settings.
  • This page should interact with a custom D-Bus service, for example:
    com.victronenergy.settings.dummy
    with paths like /update, /install, /uninstall, etc.

Where I need help:

  • How can I properly link this new service to a QML page inside the Settings menu?
  • What changes are needed in GUI-v1 to make the service discoverable by the Settings page?
  • Is there a specific pattern, file, or structure I need to follow to register the service?
  • How do I bind D-Bus paths to QML components (e.g., buttons, toggles) so that changes made in the GUI reflect on the service?

Request:

If anyone has experience with creating custom entries in the Settings menu of gui-v1, or has examples of how to link a QML page to a custom D-Bus service, I would really appreciate your guidance!

Thank you in advance

As long as it’s for gui-v1, take a look at this: GitHub - kwindrem/GuiMods: VenusOS GUI enhancements and modifications
You can get a lot of info and experience by looking at how others have modified gui-v1.

It works the other way round :slight_smile:

  • You link the qml page to the service / it’s dbus-paths.
  • None, you modify the QML settings menu to show your settings page.
  • You design a control in the qml and link it to the dbus-path it should affect.

Just check the original qmls, for example for ESS-Settings, and you quickly figure out how it’s done.

Heres also a quite old service adding a UI component - should give you ideas as well:
