@Doekse: A few months ago a user posted in this topic 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?
