I'm sure this should be easy but I just can't seem to get my head around this:-

[topic  
`switch` can be used to change device state. The message will be something like this: `{ topic: "switch", payload: { value: (1|0) } }`  
"]  
and this:-  
[{  
topic: "switch",  
payload: {  
value: 1  
}  
}]  
is what I am looking at but I just cant seem to get the inject node set up  
everything I have tried when I debug from the node, the Value no longer appears to be there

this is what I start with  
deviceId: "db1241be-ca6c-46d1-9606-9067fbc128ba"  
deviceType: "switch"  
name: "lounge colour2"  
value: 0

this is what I end up with  
deviceId: "db1241be-ca6c-46d1-9606-9067fbc128ba"  
deviceType: "switch"  
name: "lounge colour2"

(the value: no longer there)

I really hope this make sense to someone

Can you post what you've currently got in the inject node. I assume it will be something like:

```
{ value: 1 }

```

And the payload type will be set to JSON. I'm finding your question a bit difficult to follow.

Change it to:

```auto
{ "value": 1 }

```

JSON requires "quotes" around all strings.
