Hello,
I'm trying, with node red dashboard, to configure rate limit with a slider. But on delay and inject nodes, i don't see how to put a context variable in the delay. Any idea how to proceed to manage a delay from a context variable.

Hi and welcome to the forum.
What can help you in these times is to make a very simple flow that does only that specific thing.
When you say `context`.... That is at the flow level or specific to some code you wrote in a `function` node?
If it is at the flow level:
You will need to use a `change` node to do what you want.
Then when you open the `change` node you change it to something like:
Then the `msg.delay` will have the value from your context.
But if it is from a function node, slightly different.
But I'll leave it here for now.

Yes indeed I want to use it with the flow, thank you for this answer I will try right away

You will also have to tick the option in the node to allow the delay to be adjusted by `msg.delay`.
And!
Don't forget that the value is in MILLISECONDS......
😉
It can catch you if you forget that.

Yeah, it's caught me a lot of times.
You want a 5 second delay and enter 5 as the value.
All good. 🙂
