How do I get signalk data into node red

[gniersma]

yep, try version 0.9 alpha. I'd never used node-red or even done any java scripting before and within an hour had a bunch of dashboards running off signal K data. I found I had to use some of the delay/smoothing functions to avoid too many data points going to the charts I was using though (because I wanted charts of pressure tracking over several days).

I got node-red running again on 0.9.0 alpha. Had to throw away .node-red/flows_openplotter.

I also get a the message a lot of datapoints  ?
Can you explain why you add the delay function and how you implement smoothing functions ? 


thx G.
