Compatible Hardware
The app automatically detects your device model when you connect. Different models expose different features. For example, only WVC-PRO, WVC-PRO-6, and SSA show spectrum analysis and oscilloscope views, and the Smart Home tab is only visible when the connected WVC is running firmware 3.9.0 or newer.
