Home kit on Appletv with ethernet connection
My appletv is connected to ethernet via cat-5 ethernet cable. Can the appletv support homekit sharing to matter devices? I.e. can it still connect to matter device via wi-fi?

If the wired ethernet and the Wi-Fi are grouped as one logical network on the router, then it is transparant to devices, and either connection method will suffice for devices, and all can communicate with each other if needed.
