@Doekse: A few months ago a user [posted in this topic](https://community.homey.app/t/update-multipan-firmware-to-gsdk-4-6-proven-stable-by-sonoff/154725) information on a firmware update from Silicon Labs (manufacturer of the Zigbee/Thread radio in the recent Homey Pro models).

That update apparently is focussed on fixing (communication) issues in a multi-PAN setup, like in Homey Pro.

I am not sure about the relevance and validity of that information. However, are your colleagues looking into this update and whether it might also help in improving the Matter-over-Thread issue this topic is about?
