Hello, I'm having trouble trying to work out why this logic isn't going into the last condition **if (status == "true") {** appreciate any help

```auto
var status = msg.payload.on;
//
// used to skip the startup event
var transitiontime = msg.payload.transitiontime;
node.warn("Here " + status + ", transitiontime " + transitiontime);
if (! msg.payload.hasOwnProperty("transitiontime")) {
    node.warn("transitiontime not defined, good!")
    if (status == "true") {
        node.warn("Its TRUE : " + transitiontime)
    }
}
return msg;

```

The on looks like a boolean not a string so you need (status == true) without quotes.

Thanks very much, this did the trick

**if (status === true) {**

You could probably also use  
`if (status) {`  
That is not _exactly_ the same as `=== true`, which will only pass the test if status is a boolean and is true. The alternative will, if given a value that is not boolean, convert it to true or false based on its value, so a variable which is undefined will count as false, and a number value 0 will count as false, but anything else is counted as true (I think, there may be others I have forgotten).  
So if your value coming is known to be a boolean true of false then you can certainly use the alternative.
