OK try this to get the idea...

flow surrounded by ``` so that you can import it...

Flow requires both a PIR1 and PIR2 input before it starts...  
There are many ways to do this but hopefully this way will help you understand what you need to do...

Attach a debug node to each of the outputs of the function node and see what shows up.

OK so you are sending temp AND PIR to the `PIR(1,0)` node.

But you only check to see if `msg.payload` is `1` or `0` i.e. PIR on or OFF.  
If `msg.payload` is 1 you then check to see if `msg.payload` is either LESS THAN 0 or between 10 & 50. But the switch only passes on values of 1, which isn't one of the options.

My suggestion would be to store the PIR value as a flow variable ( see my earlier flow example uses a `Change` node to set `flow.PIR` to `msg.payload`) and then from the temp output from your function have a `Switch` node that checks on the status of `flow.PIR`

hi Srijan,  
I am facing the same problem.  
can you help me to split a string into 4 real separate values?  
i am trying to write the function code but not getting the result.

Here is one way to do it. Use a `change` node to remove the `[]` with two replaces of nothing, then use a jsaoata expression - `$split(payload,',')` - to 'split' the remainder into an array

```auto
[{"id":"846aa32f.9c4a4","type":"change","z":"196c2b5b.d805c5","name":"","rules":[{"t":"change","p":"payload","pt":"msg","from":"[","fromt":"str","to":"","tot":"str"},{"t":"change","p":"payload","pt":"msg","from":"]","fromt":"str","to":"","tot":"str"},{"t":"set","p":"payload","pt":"msg","to":"$split(payload,',')","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":420,"y":360,"wires":[["df4e419b.5e2c4"]]}]

or just feed it into a json node which will output the array...  
and then maybe into a split node to send 4 values... if needed.

Much better than my idea!!

Thanks so much for posting the example flow. It helps us beginners tremendously and makes learning Node Red a little easier.

Hi, I read the things above but can't seem to get the values of t1 and t2 to put in a graph.

I got this far:  
var output = msg.payload.split(",");

var t1 = parseInt(output[0]);  
var t2 = parseInt(output[1]);  
var p = parseFloat(output[2]);  
var msg0 = {payload:t1};  
var msg1 = {payload:t2};  
var msg2 = {payload:p};  
return [msg0 , msg1 , msg2];

But I guess I get NaN because msg0 is: t1:20.26 But I just want the number/value.

Correct, you would need to remove everything up to the `:` before you try to use `parseInt` function. Try splitting again on the colon, to separate the key from the value, like this:

```auto
var output = msg.payload.split(",");
var [k1, v1] = split(output[0], ':');
var t1 = parseInt(v1);

```

I like to use a `change` node with a JSONata expression that uses a regular expression to find all of the `key:val` pairs, and reassemble them into a single object:

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/b/9b485daf271308980dca3b2b62094542bf9528f9.png)

Here is the expression I used:

```auto
payload.$match(/([^:]*):([-.\d]+)[,\n]?/).[groups] {
    $[0]: $number($[1])
}

```

The nice thing about having all the keys and values is a single msg object is that you can pass the same data around to multiple ui nodes, and each one can choose which value to display by specifying the field name.

But I know that's pretty advanced syntax, and most people don't like it because it may be hard for someone else to maintain that code in the future. If you prefer to use a Javascript function, you may be able to get away with `eval`uating that string wrapped in curly braces, like so:

```auto
eval("msg.payload = {" + str + "}");
return msg;

```

But that is usually not good practice -- it relies too heavily on the format of the data string to be valid JS object syntax.

Hi shrickus, Thanks for the help I'm going to try the first part of your reply, that's already difficult enough for me :-). I know almost nothing about coding that's why I like Node red.

![Schermafbeelding 2022-04-14 om 22.47.23](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/c/0/c069320fc3350bbe965604cbd186ee040601f246.png)

I did this:  
var output = msg.payload.split(",");  
var [k1, v1] = split(output[0], ':');  
var t1 = parseInt(output[0]);  
var t2 = parseInt(output[1]);  
var p = parseFloat(output[2]);  
var msg0 = {payload:t1};  
var msg1 = {payload:t2};  
var msg2 = {payload:p};  
return [msg0 , msg1 , msg2];

But got the above error. Like I said I'm a Noob in coding. Do not Know what k1 and v1 does?

Try

```auto
msg = msg.payload.split(":").slice(1,4).map(e => {
    return {payload:parseFloat(e)}
});
return msg;

E1cid, Thanks.

var output = msg.payload.split(",").slice(1,4).map(e =\> {  
return {payload:parseFloat(e)}  
});

var t1 = parseInt(output[0]);  
var t2 = parseInt(output[1]);  
var p = parseFloat(output[2]);  
var msg0 = {payload:t1};  
var msg1 = {payload:t2};  
var msg2 = {payload:p};  
return [msg0 , msg1 , msg2];
