Looks like v12.6.0 will include new tools for matter in the developer tools. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/2/02944ea303a7974f6986e626bd9aeb11fff5c3dd.png) ---

Nice, this error msg implicates my Pro 2019 gets Matter functionality just by updating firmware! [https://tools.developer.homey.app/tools/matter](https://tools.developer.homey.app/tools/matter) shows the same message for my Pro 2019 😬🫣 ![Screenshot_20250809_142323_Chrome](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/7/67631084bb610616c9263eb1b9fd974cab0aab12.jpeg) ---

Looks like this is postponed to 12.7. ![CleanShot 2025-08-15 at 10.48.01@2x](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/8/98e8ad4945c67b986a259a327a16c705d757c998.png) ---

Looks like it. The Changelog for v12.6.0-rc.6 doesn’t mention anything about it. ---

V12.6.0, just got released, so a RC of 12.7.0 cannot be that far away. ---

Looks like 12.7.0 cannot be far away. A release candidate is already out. ---

Matter Adds support for migrating Matter devices when a new cluster is added. Adds support for setting the duration parameter on dim level, color and color temperature Flow cards. Adds support for color looping of lights (when the device supports this). Adds support for configuring the on/off transition time. Adds support for configuring the on/off state after a device has lost power. Adds support for configuring a temperature off… RC often is almost the same as stable. _ **BUT** _ you shouldn’t install RC firmware @ main Homey (me guilty as charged 🤪) unless you can rollback when you created offline backups of previous firmware versions ---

I think I will stay away from prerelease software. Cannot risk reducing the WAF of my setup. Looks like a lot of nice features are coming in the next release.
