Platform connection paths
No model-specific platform route is established in the supplied evidence. A controller role or radio alone does not prove accessory compatibility.
Every listed route remains conditional until the model, region, controller, network and feature requirements are checked in your home. No physical pair test was performed.
What to verify before setup or purchase
Original research issue HA_USB_IS_NOT_STANDALONE: ROLE CONDITION. Consult the cited source before relying on this field.
Use the device label, manufacturer app and current official support article to confirm your US variant and firmware. For switches, locks and thermostats, also verify the physical installation requirements before buying.
