Why move it
Your Home Assistant server might sit in a basement or a server rack, while your Z-Wave devices are spread across other floors. A Connect ZWA-2 plugged into that server has to reach them through floors and walls, next to metal and other transmitters. The ZWA-2 placement guide (opens in a new tab) lists these, including server rack housings, computers, and routers, as sources of interference.
Set it up
Place Connect AUX-2 near your Z-Wave devices, following Choosing a location (opens in a new tab). A wired network connection gives the most reliable radio link. See Power and network options (opens in a new tab).
Plug the Connect ZWA-2 into the USB-A port of Connect AUX-2. Home Assistant discovers it automatically. If the adapter was connected to your Home Assistant server before, Home Assistant migrates it to the new location.
For details, see Using a Connect radio adapter over the network (opens in a new tab). For supported adapters, see Specifications (opens in a new tab).
