I have 6 input to NR and I like to check if they all are "on" and the set the payload to "all on".  
Isn't there a simple node that can do this?

See [this article in the cookbook](https://cookbook.nodered.org/basic/join-streams) for an example of how to join messages into one object.

Hello funhall,

you could use some simple javascript in a Function node with the Logical Operator AND (&&) to compare all values.

For Example :

```auto
let a = "on";
let b = "on";

if ( a === "on" && b === "on" ) { 
msg.payload = "all on"
return msg;
}
else {
return null; // dont return anything
}

```

</div>

once all your inputs are in one object (after the join) use a function node...

```auto
if ( msg.payload.input1 === "on" && msg.payload.input2 === "on" && msg.payload.input3 === "on" /* etc etc etc */) { 
  msg.payload = "all on";
} else {
  msg.payload = "not all on";
}
return msg;

```

Thanks so much for your help. But I cant get it to work.  
Somethings wrong with the payload.  
But maybe it is possible to check the Global. variable in the function node directly.

I found a solution. Thanks guys

```auto
if ( global.get("kisteexit") === "closed" && global.get("kistestate") === "closed" && global.get("doorroom2") === "closed" ) { 
  msg.payload = "all on";
} else {
  msg.payload = "not all on";
}
return msg;

```

Had you given even the slightest clue that the values were stored in the context then you would have received more helpful responses.
