OpenWrt: Monitor your IPv6 Status
TL;DR
An automation system was developed to monitor IPv6 status on a Deutsche Glasfaser internet line, ensuring immediate notifications for outages. This solution leverages OpenWrt and Home Assistant to track changes in the WAN interface.
✦ Why It Matters
Set up a monitoring system for your IPv6 status to receive immediate outage notifications.
Key Takeaways
- Set up an OpenWrt router to monitor IPv6 status.
- Use MQTT to relay status changes to Home Assistant.
- Implement a script to check IPv6 health via Hotplug.
- Create automations in Home Assistant for immediate alerts.
How It Works
The solution uses the Hotplug mechanism in Linux to trigger a script whenever the 'wan6' interface changes state. This script queries the network status using the 'ubus' command to check for IPv6 addresses and prefixes.
If these are absent, it sets the status to 'unhealthy' and sends a message to the MQTT broker, which Home Assistant listens to for automation.
