Real-Time Physical Status Indicator for GitHub Repository Updates - n8n Workflow

Developers and DevOps Engineers who need real-time, physical status indicators.
Teams leveraging n8n templates for devops_monitoring.
Smart home enthusiasts integrating IoT devices with development workflows.
Users looking to utilize the GitHub n8n trigger and Home Assistant n8n node together.

This specialized n8n workflow template provides immediate, highly visible feedback on the status of your Git repository. Traditional digital notifications can often be missed, but this n8n automation creates a clear physical alert. The workflow is designed to detect any activity—such as a push, a new pull request, or an issue update—and instantly turn a configured smart light to a specific color, typically red, signaling that attention is required. This integration between the GitHub n8n trigger and Home Assistant is a fantastic example of using n8n for continuous devops_monitoring and ambient intelligence. Deploying this n8n workflow is quick and effective, ensuring critical repository changes are always noticed.

This automation sequence starts with a dedicated n8n trigger and completes with an IoT action:

1. GitHub n8n trigger: The workflow initiates using the On any update in repository n8n node (a GitHub Trigger). This n8n trigger listens for all event types (*) configured for a specified repository (e.g., dummydavid/DemoRepo).


2. Detection and Execution: As soon as an event occurs (a push, PR merge, issue opened, etc.), the GitHub n8n node captures the payload and forwards the execution.


3. Home Assistant Action: The subsequent n8n node, named Turn a light red (Home Assistant node), receives the data. It calls the Home Assistant service light.turn_on.


4. Physical Notification: The n8n workflow instructs Home Assistant to target a specific light entity (defaulting to light.lamp) and sets its color using the RGB value [255, 0, 0], ensuring the light immediately turns red.

To deploy this n8n workflow template, follow these steps:

1. Import: Copy the provided JSON code and import it into your n8n instance via the 'New' menu -> 'Import from JSON'.


2. GitHub Credentials: Click the On any update in repository n8n node and update the 'GitHubApi' credential with your active GitHub API key and access token.


3. GitHub Configuration: Configure the Owner and Repository fields to point to the exact repository you wish to monitor.


4. Webhook Setup: Since this is an n8n trigger, you must save and activate the workflow. n8n will provide a Webhook URL that you must register within your GitHub repository settings (Settings -> Webhooks).


5. Home Assistant Credentials: Click the Turn a light red n8n node. Add or update the 'Home Assistant API' credential, ensuring it points to your Home Assistant instance and uses a valid long-lived access token.


6. Light Entity Configuration: Crucially, modify the parameters within the Home Assistant n8n node to replace the default entityid (light.lamp) with the specific entityid of your desired smart light, and optionally adjust the rgb_color array to change the notification color.

This simple yet powerful n8n workflow utilizes two main nodes:

GitHub Trigger (On any update in repository)
Function: Acts as the primary n8n trigger, listening for real-time events from a designated GitHub repository.
Key Configuration: Set to listen for Events: (all events) and configured with a specific Owner and Repository name. Requires GitHub API credentials for authentication.

Home Assistant (Turn a light red)
Function: Executes a service call within Home Assistant to manipulate an IoT device based on the n8n trigger.
* Key Configuration: Domain: light, Service: turnon, and uses service attributes to define the physical action. Key parameters include entityid (e.g., light.lamp) and rgb_color (=[[255,0,0]]), which dictates the light that turns on and the color it displays.
