signalk-instrument-widgets
Add live instrument widgets to your chartplotter. Works with any chartplotter that supports Signal K plotter extensions (such as Freeboard-SK).
- Gauge — a dial for any numeric value.
- Meter — a 0–100% bar for ratio-style values.
- Switch — shows an on/off value; tap to toggle it.
- Display Value — a clean text readout: a small label on top, the live value large in the middle, and an abbreviation below — e.g. "Speed over ground" / value / "SOG".
Using the widgets
In your chartplotter, press and hold an empty widget area to add a widget — its setup panel opens automatically. Press and hold a placed widget to reconfigure or remove it.
Each widget is configured on its own: pick the value to show, choose the units, and set the range and labels. So you can place two gauges showing two different values side by side. Your settings are remembered for each widget.
Units follow your server's display preferences by default. The Units setting starts on "Server default", which shows each value in the unit you've chosen in the Signal K server's Unit Preferences — so most widgets need no unit setup at all, and changing a preference on the server updates the widgets to match. Pick a specific conversion instead only when you want that one widget to override your server preference.
Demo switch
If your server has no real switches to control (for example a demo or playback setup), the plugin can provide a demo switch so you can try the Switch widget anywhere. It is on by default and can be turned off in the plugin settings.
