hi evryone can anyone help me with this :  
i wana simulate code can control a system {pump-low start and stop by switch after pump-low start the pump-décolorant and pump-scalaut starting after 2 sec also pump-high start after 6 sec when switch is false all pump stoped}

but i get northing in debug any advise  
here is the code :  
\<  
// Declare variables for the pumps  
let pumpLow;  
let pumpDecolorant;  
let pumpScalaut;  
let pumpHigh;

// Declare a variable to track the status of the pumps  
let pumpStatus = "off";

// This function is called when the switch is flipped  
function startPumps(msg) {  
// Check the value of the switch  
if (msg.payload === true) {  
// If the switch is turned on, start the pump-low  
pumpLow = setInterval(function () {  
console.log("pump-low started");  
}, 1000); // Run the function every second

```
    // Set a timeout to start the pump-decolorant and pump-scalaut after 2 seconds
    setTimeout(function () {
        pumpDecolorant = setInterval(function () {
            console.log("pump-decolorant started");
        }, 1000); // Run the function every second

        pumpScalaut = setInterval(function () {
            console.log("pump-scalaut started");
        }, 1000); // Run the function every second
    }, 2000);

    // Set a timeout to start the pump-high after 6 seconds
    setTimeout(function () {
        pumpHigh = setInterval(function () {
            console.log("pump-high started");
        }, 1000); // Run the function every second
    }, 6000);

    // Update the pump status
    pumpStatus = "on";
} else {
    // If the switch is turned off, stop all pumps
    stopPumps();
}

```

}

// This function stops all pumps  
function stopPumps() {  
clearInterval(pumpLow);  
clearInterval(pumpDecolorant);  
clearInterval(pumpScalaut);  
clearInterval(pumpHigh);  
console.log("all pumps stopped");  
pumpStatus = "off";  
}

// Send the pump status to the output  
return {  
payload: pumpStatus  
};

setTimeout functions may eventually create all kinds of problems, can I suggest a more node-red "way" of implementing this ?

thanks
