NMEA Integration
KnotWise supports importing instrument data from your onboard electronics via NMEA, eliminating manual entry of navigation values and reducing the risk of transcription errors.
Supported standards
- NMEA 0183 — currently supported
- NMEA 2000 — in development, coming in a future update
What data is imported
When connected, the following log entry fields can be populated automatically from your instruments:
- Position (Latitude / Longitude)
- SOG and COG (Speed and Course Over Ground)
- True and Apparent Wind Speed and Direction
- Barometric Pressure
How to connect
NMEA 0183 connection is configured in Settings → Instruments. Your device must be on the same local network as your NMEA 0183 data source — typically via a WiFi gateway such as Yacht Devices, Vesper or a similar NMEA-to-WiFi bridge.
Manual override
All NMEA-populated fields can be manually edited at any time. Instrument data is a starting point — you remain in full control of every log entry.
