This n8n workflow automates the process of changing a smart light’s color to red whenever there is any update in a specified GitHub repository. It is designed for developers or teams who want a visual, real-time indicator of repository activity.
**Workflow Steps:**
1. The process begins with the ‘On any update in repository’ trigger, which listens for all types of events (pushes, pull requests, issues, etc.) in the specified GitHub repository.
2. When any update occurs, the workflow activates and passes the event to the next node.
3. The ‘Turn a light red’ node uses Home Assistant to turn on a specified smart light (by default, ‘light.lamp’) and sets its RGB color to red, providing a visual cue that the repository has been updated.
**Key Details:**
– Uses GitHub webhooks for real-time updates.
– Integrates with Home Assistant to control smart home lighting.
– Includes notes on customizing the light entity and color settings through user-friendly notes.
**Practical Use Case:**
This workflow is ideal for development teams tracking multiple projects. By visually signaling recent activity in a workspace or server room, team members can quickly assess activity levels or updates without checking their computers.
**Additional Customization:**
Users can modify the entity_id of the light and change the RGB color via a color picker, making it adaptable to different smart lighting setups and color codes.
