GitHub to Home Assistant: Turn Light Red on Repo Updates (n8n)

Make your Home Assistant alert you instantly: Light turns red on GitHub updates (n8n)

This n8n workflow watches your GitHub repository for any new activity and automatically tells Home Assistant to turn a light red when updates happen—perfect for visual “something changed” awareness around your workspace.

What this workflow does

Built for fast operational visibility, the workflow is designed around one clear trigger and one clear action:

• Triggers on GitHub repository activity using the node “On any update in repository”.
• Detects updates such as pull requests, issues, and pushes (as examples of repository updates).
• Calls Home Assistant to turn on a light and configure it to turn red, signaling that an update occurred.

Use cases

• SaaS operations visibility: Get an immediate red-light cue when new issues or pull requests are created.
