Device Monitoring and Data Display

basic

Device Cards

When you connect to one or more devices, the Devices tab shows each device as a card with a real-time data preview. Tap any card to open the full monitoring view.

Each card displays:

  • Device name
  • Connection status indicator
  • A live data graph showing the primary measurement (voltage, temperature, etc.)

Full Monitoring View

Tap a device card to open the detailed monitoring screen. What you see depends on your device model.

Voltage Graph

All WVC and HPVM devices display a real-time voltage graph. The graph updates continuously and shows the last several seconds of data. The Y-axis auto-scales to fit your readings.

Temperature Graph

WVC-PRO devices show a temperature graph from the built-in temperature probe. WVC-PRO-6 devices show up to three temperature channels from the daughtercard probes.

Tip

You can switch between Fahrenheit and Celsius in the app's Settings tab or on the device monitoring screen.

Volume Level

WVC devices display the current volume level. This is a read-only display showing what the knob or system has set — volume is controlled via the physical knob, RTC, or mesh network, not from the app.

Spectrum Analysis (WVC-PRO / WVC-PRO-6 only)

PRO devices include real-time FFT (Fast Fourier Transform) spectrum analysis. This shows the frequency content of the audio signal passing through each channel.

  • WVC-PRO: Two channels displayed side by side (left and right)
  • WVC-PRO-6: Up to six channels displayed in a grid (three rows of two)

Each channel shows 15 frequency bands as vertical bars. Taller bars indicate more energy at that frequency. This is useful for:

  • Verifying that audio signal is present on each channel
  • Checking frequency response across your system
  • Identifying if a channel is clipping or has unusual frequency content

Oscilloscope View (WVC-PRO / WVC-PRO-6 only)

PRO devices also include a real-time oscilloscope view showing the raw audio waveform for each channel.

  • WVC-PRO: Two waveforms (left and right)
  • WVC-PRO-6: Up to six waveforms in a grid layout

The oscilloscope is useful for visually inspecting signal shape, detecting clipping, and comparing channels.

Graph Settings

You can customize the monitoring display:

  • Channel toggles: Enable or disable individual data channels to focus on what matters
  • Graph smoothing: Adjust how much the graph line is smoothed (less smoothing = more responsive, more smoothing = cleaner lines)
  • Time window: Control how many seconds of data are visible on the graph

These settings are accessible from the device's settings screen (tap the gear icon).
