Does anyone know if the rudder is set to turn to port should the rudder position sensor be reading + or - ?

The sign should be handled by rudder calibration... Is this in the opencpn dashboard display?
Yes and in the pypilot plug-in rudder calibration screen
It shows negative when I turn to starboard and positive when I turn to port. Seems to be opposite of what it should be?

positive is port for nmea output sentence
hmm.. it may be that pypilot is treating rudder angle with the opposite sign of convention. I haven't worked on this bit for a while, and surprised no one brought it up. I would treat positive as port for now, but in a future version i may switch it, but this will only affect nmea and signalk output and communication. Everything should work ok assuming port is positive. Thanks for the feedback.

I just finished installing and calibrating my rudder position sensor and noticed the same thing. If I treat Port as + and Stbd as -, the rudder movement commands are correct, and the center command finds center, but the rudder display shows Port and Stbd rudder directions as swapped.

Thanks for reporting this. For this version, just please swap the display in your head.. and expect pypilot future version to correct this. I will do a lot of testing before releasing a version and hopefully fix this in the next one.
