Ilker - Hey @Scott Bender , in pathmapper plugi...

Hey @Scott Bender , in pathmapper plugin, is there a way to publish the values within an object as a separate path? For example, navigation.attitude has a value of {"yaw": X, "pitch": Y, "roll": Z} . Is there a way to publish these as navigation.attitud.yaw, navigation.attitude.pitch, etc.?

No. Pretty simple to do in node-red

IlkerOP•7d ago

Yeah, Node Red will be difficult for this user. Let me see if I ChatGPT can spit out a plugin doing this 🙂

Scott Bender•7d ago

Are you using node-red at all now?

IlkerOP•7d ago

I am using it but this is for a Saillogger user you mean whether Saillogger uses it?

Scott Bender•7d ago

No, thought this was for your boat how does this relate to Sailogger?

IlkerOP•7d ago

Saillogger can do detailed NMEA 2000 monitoring A user is trying to monitor navigation.attitude which is an object, which needs to be split out to its keys and values for monitoring

Scott Bender•7d ago

Wouln'd it make more sense to make Sailloger able to handle it?

IlkerOP•7d ago

It probably makes sense but I need to think about it, there is a lot of composite values out there and turning each into a value of its own can bloat the datamodal There probably is a way to do it in a smart way but may be non-trivial NMEA monitoring is generic, so needs to work across all fields

Scott Bender•7d ago

if your user is using node-red already, I can throw together a flow for them

IlkerOP•7d ago

If you have it handy, I can recommend it

Scott Bender•7d ago

they need all three values?

IlkerOP•7d ago

Yes

Scott Bender•7d ago

hmm. no units for the first two. Do you needd that?

IlkerOP•7d ago

Thanks! Units should not matter Stupid question, how do you deploy this to Node Red?

Scott Bender•7d ago

Top right menu, Import Can copy/paste or import a file

IlkerOP•7d ago

Perfect, worked like a charm, thank you
