Flow malfunctions when user defined update intervals are set

General
, ,
1

Hello,
I'm building a weather dashboard with OpenWeatherMap API. Users can select if they want to give input as country/ city or latitude/ longitude.

By default, weather updates at 30-second intervals (requirement of the project) but, the user can set the update interval to anytime he wants (under the "Settings" tab).

Dashboard updates at 30-second intervals. But, I cannot figure out how to connect the user-defined update interval to this flow.

Can someone please help me?

You also need to add something to catch errors and stop requests, a stop start would also be good.
Here is how I might go about it using dashboard forms and passing all info along message, no need to use context.
Hope it helps

Hey, I've had the same problem as you and came to the following code, which is doing well:

let i = context.get('rainbow') || undefined
//let intervall = msg.payload.intervall;
context.set('intervall', msg.payload.intervall);

if (i === undefined && msg.payload.start === 'start') {
    node.warn('starting');
    global.working = true;
    i = setInterval(function(){
        node.send(msg);
        node.done();
    }, context.get('intervall'));

    context.set('rainbow', i);
}

if (i && msg.payload.stop === 'stop') {
    node.warn('stopping');
    clearInterval(i);
    context.set('rainbow', undefined);
}

In this example you will need something like a button which is giving the function-node a payload start or stop and of course you have to overwrite the context variable 'intervall'
