Magnetic Variation & headingTrue
Hi, I have openplotter set up with pypilot and I'm now able to see my headingMagnetic in SignalK. I'd love to also have headingTrue (e.g. for KIP's Wind Steering Display). It seems SignalK needs a source of magneticVariation. Neither of my GPSs seem to include it in their output, the key is there in SignalK as coming from my GPS, but its value is null. How do most people get variation data? It seems like there should be a plugin to compute it from WMM but I can't find anything.
