see above:

I do not know if you have navigation.position or environment.outside.temperature, but seeing your list of wind data, looks that you may need signalk-derived-data plugin for environment.wind.directionGround (DEPRECATED and unchecked in your list).

One can calculate environment.wind.directionGround from true heading and true wind anglen (you need these, at least). signalk-derived-data plugin can do this for you.

For environment.outside.temperature you would need a sensor. It is a sensible requirement for a weather station that it submits a temperature value for your (moving) spot.

You can study your existing instruments, maybe the data is available but not transmitted for some reason. For example, I have two temperature values available, one from the barometer and one from the ultrasound wind sensor. My barometer is inside the cabin so I had to disable its temperature value in favor of the value given by the wind sensor.

If you have no luck, the easiest way is to purchase a sensor, which can be plugged in on your NMEA-2000 bus (or its Raymarine etc. derivates with an adapter), for example https://www.yachtd.com/products/grade calculator/sensors.html

I just learned about SignalK integration with Windy, thanks for the useful sharing

thanks for the suggestions.

i have now enabled debugging and the environment.wind.directionGround is enabled.

but i dont have the datapoints
environment.wind.directionGround
environment.outside.temperature (no sensor)

in the data browser

and the log now says:
Apr 20 11:31:29 2025-04-20T09:31:29.092Z signalk-windy Not submitting position due to lack of position, wind speed, wind direction or temperature.

But i do have position and windangle/speed

Thanks

• navigation.position,
• environment.wind.directionGround
• environment.wind.speedOverGround
• environment.outside.temperature

What data is missing, if any, is printed by the plugin in the debug log. If something is missing, it does not send anything to Windy.
