Yes, an additional module will be required. While Matter support will not require anything additional.
Can what the form factor of the module be shared? GPIO, USB, etc?
I'm looking at doing a refresh of my z-way systems and looking to move from Raspberry Pi 4B's with PoE modules to Compute Module 4's with an IO board that has PoE integration and UPS capabilities builtin. I'm interested in Zigbee but the form factor would play a part of my decision since there is limited room on cases for the Compute Module 4's.
It seems to be working now even when setting MultiCmd back to supported=true.
They are several each second!
