Node:  
`change`

```auto
[{"id":"821066fcf882d5bf","type":"change","z":"a1911aa3.c45be8","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"LEDSTRIP[6]","tot":"flow"}],"action":"","property":"","from":"","to":"","reg":false,"x":680,"y":3200,"wires":[["583eb6e3b1c0ce91"]]}]

```

The line:  
`LEDSTRIP[6]`

I would prefer to be a bit more _flexible_ in the value.

More like (example):  
`LEDSTRIP[{{msg.led}}]`

Ok, I'll actually try that now, but I have little hope.

Ok, that's not going to work. Error straight away.

Have you tried `LEDSTRIP[msg.led]`
