output battery volts to signal k

[Saqqara]

Since you are measuring this anyway, perhaps we can get this in signal k? 

Not important for me as I have another ADC chip, but this could simplify hardware for some.

so far pypilot has internal signalk it uses. Try running signalk_client from the console.

If you want to get this into the node signalk, it needs translation since the fields are different, but we should do it.

Currently translates heading, pitch and heel. Any other useful fields besides voltage which can be translated?

pypilot reads what is powering the motor controller. So if you have a 48 volt lithium battery, but power the pypilot controller through a 12 volt regulator, it would not be the battery voltage.

Rudder angle, since that may be determined from sensors wired to the controller.

I assume OpenCPN can be configured to output things like VMG, XTE, BRG, RNG, TTG, which would be useful for instrument display.

yes, pitch, heel and heading are output on nmea0183 as well as rudder angle already and opencpn sees it. The other values like TTG etc are computed by opencpn and have nothing to do with the autopilot.

Do you know the path of the field it should use for rudder angle and battery voltage in the signalk node server? I can add it for the next openplotter version.
