Points of sail in Signalk

[Cfokke]

Hello forum,
I have successfully connected my instrument data (nmea0183) to my Rpi 4 onboard. I overlay the instrument panel as a ‘slide-over’ on my iPad-navigation chart plotter. I wish to show all the points of sail associated with the apparent angle data e.g 40-55degrees== ‘closed hauled’, 55-75 degrees ==‘close reach’ and so-on through the whole 360 degree rose. It is so that I can display this for novice sailors. I tried using the in-built edit-zones but no luck so far. Any ideas of how to go about this or whether this feature is already availed in some of the plug-ins. It would be useful to add to any auto-logbook file as well.

You could create a Node-RED flow that outputs say navigation.wind.pointOfSail with the text that you want, then use that in InstrumentPanel.

For log book usage Node-RED has also support for removing fluctuations: when the wind is fluctuating around for example 55 degrees output the new value only when the wind's stayed in that point for some x seconds. With a bit of extra logic you can even remove the lag: output the new value with timestamp for 60 seconds ago when the value has bee in the new value area for 60 seconds.
