Dashboard 2.0 chart internet requirement

Sorry if this is something documented or there's already posts about it, but my googling hasn't dug anything up.

I'm putting together a project that the server only has internet access some of the time (it's a RPi in an instrument.) It seems that if the server doesn't have access to the internet, the chart in Dashboard 2.0 is non-functional (i.e. it's still there in the client dashboard page, but no trace gets drawn.)

I'm surprised this is something I'm struggling to find info on unless there's something odd about my install.

Is this standard behavior and is there a known work around?

Thanks

I've not checked the details of the D2 nodes. If it is a problem and you can live without Dashboard itself, UIBUILDER can be used completely offline - including all of the documentation.

Hi @Harvs - welcome to the forums. I can confirm that for Dashboard 2.0 to operate, it only needs a connection to the Node-RED Server, which if installed onto your Pi, means there is no requirement for a public-facing internet connection.

Thank you for your reply, that narrows it down to being something in my setup that's causing the issue. Great, I'm sure I'll work out what's going on.

And thank you for the excellent Dashboard and video tutorials! It's brought me back to looking at Node-RED again.

:heart: thanks for the feedback, so pleased to hear it!

If anything in your implementation requires an external resource, you can configure (in setting.js) a local web host on your Node-red server, and put a copy of these resources there.

That's handy to know!
