Missing unit for directionGround #639

Open jobarne opened 2 years ago

jobarne commented 2 years ago

When running signalk nodejs server and an Airmar WX220 weather station, wind data comes in as environment.self.directionGround but with no unit specified.

Is there a way of updating the specification so that the unit is set correctly (to rad)?

Anyone?

How do you get the data into the server? Because there is no environment.self.directionGround (let alone environment.self.directionGround) defined in the current Signal K specification.

There are 2 paths for absolute wind direction, directionTrue and directionMagnetic.

Thanks for your reply!

I am sorry. It should be environment.wind.directionGround , I assume the server uses the individual js files in n2k-signalk pgns directory, There is a environment.wind.directionGround mapping in 130306.js file but I do not understand how the unit is specified...
