🚨 IMPORTANT — UPGRADING FROM VERSION 7.1.4 🚨

Preferred: migrate before installing version 8

Install version 7.1.4 first, then use Upgrade to v8 from any KNX Ultimate node.

The migration is fully automated with the push of a button

If version 8 was installed directly from an older v7, restart Node-RED and open the editor: the built-in recovery bridge offers the same protected backup, package installation, conversion and Deploy. Legacy KNX AI nodes still require manual replacement or removal.

Follow the upgrade steps to keep your flows working.

Native seamless integrations

• Philips Hue: install node-red-contrib-hue-ultimate.
• Matter Controller and Matter Bridge: install node-red-contrib-matter-ultimate. Select your existing KNX gateway in those nodes to enable KNX integration. The package can also work without KNX Ultimate.
• AI-driven KNX control, on-field diagnostics and unit testing for KNX installers: install node-red-contrib-cerebrum-ultimate.
