This took a little while instead of doing more deserving items on the jobs list - but it works! Wrote it up for the opencpn forum but maybe there might be someone interested on here....
Briefly, the wonderful node-red is available online >

Sort of swiss army knife fr data - take any input you can think of, fiddle with it then send it to anywhere you can think of. Pretty much. So now every 6 hours it sends an email to saildocs, gts the attachment when it's sent back and saves it into dropbox, once with data/time filename and once call 'current. Once the opencpn grib plugin opens the file called 'current', it does so every time you start the program. Always the latest grib automatically. Assuming you can get online to update dropbox anyway, but then if you can't get online downloading a grib ain't going to happen anyway
FRED is all online so will keep running all the time, though the free version needs you to log on once a day to keep it running.
Quick walk through - top left the Inject node is just trigger which sends something once every 6 hours, or every time you press the button on the left. To the right of that the create message function node creates the email text and sets some other things, it will run anytime something comes in to its input on the left from the inject node so once every 6 hours. Then it sends all that to the email node which sends off the email.
Then further down, bottom right is another email node - once a minute it checks for the latest emil and downloads it. THis the goes to a switch node which is set up to just let through emails from query-reply@saildocs.com. Next is a change node, this swaps the attachment around into a place where the drop box node expects to see it. Then there's another function node which renames the file with current date//time & path in dropbox the off it goes to the dropbox node to get uploaded. As well as this archived file, the flow splits off , waits for a few seconds then gets renamed as Current and uploaded. The msg nodes are just for debugging so you cn see what's going on to help figuring out why it doesn't work.
That's that
Node red code below, if you copy that, open up FRED then press CTRL I you can paste the code straight in. Probably won't work straight away, you might need to install the dropbox node which is easy, button on the control panel on the left.
So constant latest gribs plus saved past gribs . :biggrin:
