Adjust node time delay via dashboard GUI

[Shane Ringrose]

Hi all

I can't find any examples of how to adjust any node setting (e.g. time ) via the dashboard text input?

Is this possible?

If so are there any examples?

Thanks

The Dashboard is just a dashboard to interact with the the flow running in the Node-RED runtime. The Editor is the way to edit nodes directly. You can design a flow such that the dashboard can send messages to the runtime to change it's behaviour but that is up to you.

Thanks Dave

After some research I suspected this might be the case

Fingers crossed somebody can post an example on how to do this.

Thanks

well you can send (just about) any message you like from most of the widgets... but it depends what you want to change in the editor. The Info panel in the editor will tell you what each node expects and thus any inputs you can send it. You mentioned time... but none of the default nodes accept a a time input (I think - no doubt someone will correct me).

I've go a loop (timer) and I want to fire it every few seconds which could be adjustable.

I want to change this time via GUI

I can think of two different ways you could achieve what you want to do

1) have a drop down list of the "delays" you want and then use a switch node to redirect to the correct delay

or

2) Have a loop set for the smallest increment delay you need and then an a loop. If delaywanted> delaydone increment delaydone and loop through delay node again

Hi Mark

Thanks for the excellent tips

I can see my flows are going to get very big

Sometimes, using JavaScript code in a function node is easier.

In the case where you want a variable input to effect some change, code can be much easier to manage. so if you don't want to juggle nodes, you might want to write just a bit of code to do it instead.
