Pull Request Overview
This PR adds support for custom cards and panels to open the Home Assistant Automation Editor with prefilled data by introducing a new show-automation-editor event. Previously, only the core UI could programmatically open the automation editor with initial data, limiting the functionality available to custom integrations and panels.
Key changes:
- Creates a new mixin that handles
show-automation-editorevents and delegates to the existingshowAutomationEditorfunction - Adds the mixin to the base
HassElementclass to make the functionality available throughout the application - Defines proper TypeScript interfaces for the event parameters

Proposed change
ExposeshowAutomationEditor(data?: Partial<AutomationConfig>, expanded?: boolean)as a public method on theha-panel-custom. This allows custom panels (iframes) to open the Automation Editor prefilled with data.Add a new event for
show-automation-editor. This allows custom cards & panels to open the Automation Editor prefilled with data.Until now, only the core UI could open the automation editor prefilled. Custom panels (iframes) had no way to do this, because the editor initialization (initialAutomationEditorData) was only accessible inside the main app. By exposing showAutomationEditor, embedded panels can now trigger the same flow and hand over prefilled data.
Use case:
For the KNX integration we provide a Telegram Monitor. This tool shows how KNX devices on the network exchange messages with each other (e.g., a wall switch sending a telegram to a light actuator). We want to add a feature that lets the user create an automation directly from such a telegram, like so:
create_automation_from_group_monitor.mov
