hi,
Just need this last bit to work, and I will be a very happy sailor nerd.
Having Raspi 5 with Mc Arthur hat and ICM-20948 IMU with pypilot 4.0.11
I need to have this in Autopilot mode for the autohelm, but at the same time I need the IMU data to be in Signal K to calculate true wind direction. (first screencapture)
"navigation.headingMagnetic" is the data still missing to calculate my true wind angle (via derived data plugin) .... this is the reason I started the OpenPlotter project.
should be straight forward .... but appreciate any help I can get.... it's the last thing I need (until some other cool feature comes along)

- I have read that SignalK needs an authentication token. So to be sure I removed the token from security/devices and rebooted (second screencapture)
- when in "IMU only" mode the data is seen in SignalK (third screencapture)
- also I did a re-calibration from the pypilot app which was mentioned as a thing to try
should be straight forward .... but appreciate any help I can get.... it's the last thing I need (until some other cool feature comes along)
