Automate GRIB Downloads

[PaddyB]

Many Thanks

Looking a Git, one additional request I have would be as well as:

Hourly
Daily

Would it be possible to have:

"When an IP Connection occurs"

We'd be using Marina WiFi, which would not be available all the time.

Hi Simon, you can do that with node-red sending an automated email to saildocs. I have it set up to save the grib (GFS) to dropbox so opencpn always has the latest grib when it is run. I'll post the node-red flow at some point if anyone is interested.

I'd be interested to see it.  I've never used NodeRED, but am interested in having a play with it.

Could be useful for automating some things on the boat.

Node-red is just wonderful :

Try this , go to https://fred.sensetecnic.com/ and make an account. Then copy the code below and press control I to insert, paste the code in. Then you'll need to dig in and fill in email passwords and dropbox stuff then it will send you a grib 4 times a day. Really handy 

Code:
