Hey,
I succeed with an automations : when I push a button paired on Thread network, it toggle a HUE Lightbulb (Zigbee)
I paired everything with matter so I could see all devices on Home Assistant.
How the automations works behind ?
Is it a Matter "binding" functionality used or it's more the core layer of Home assistant that translates messages from Thread to Zigbee and have context on each devices ?
Thanks ! 🫶

Very simply...
Everything is integrated into HA. HA knows how it all talks to HA, and how to talk back to it.
Nothing knows about anything else. Those Zigbee devices know nothing other than what's on the rest of the Zigbee mesh (and at that, only the tiny part of it that's relevant to it)
You push the button on the Thread device, that sends a signal to HA
That signal causes your automation to trigger
HA then tells devices to take actions, based on what you wrote in the automation

Thx for this answer to be clear it's HA that control everything here.
So is there a way to create a matter "binding" from HA ?

Between Thread and Zigbee?
No... not a hope in hell
Between two Zigbee devices then sure, because Zigbee supports that
(assuming the devices support it anyway, not all do)
Matter also has binding support (Matter sits above Thread), so if the Matter devices support it then HA will be able to (if/when it has support for that)

If I understand it correctly from the purpose of Matter,
Matter should support it as well even if it's on Thread or Zigbee.

Well, no
Binding (or the Z-Wave version association) only works within a technology
So, between two Matter devices, or two Zigbee devices (on the same mesh)
Matter doesn't support Zigbee
Not that it matters, unless you run HA on a toaster you'll not notice the difference between a binding and an automation
