Node-RED version: v0.18.7  
Node.js version: v8.11.2  
node-red-node-pi-sense-hat@0.0.15

Playing with the RPI Sense Hat and I can not get multiple commands to work in a single msg.payload.  
If I send one msg.payload with:  
`R`  
and a second with  
`0,0,red,0,7,#00ff00,7,7,yellow,7,0,0,0,255`  
I get the letter ‘R’ and each of the four corners is colored.

If I send one msg.payload with:  
`R\n0,0,red,0,7,#00ff00,7,7,yellow,7,0,0,0,255`  
which should do the same thing, instead you see the entire line scrolled across the display.

Here is a flow showing the issue:  
`[{"id":"caa66d9d.b7aed8","type":"inject","z":"c3525ae7.a368a8","name":"2) color the corners","topic":"","payload":"0,0,red,0,7,#00ff00,7,7,yellow,7,0,0,0,255","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":150,"y":140,"wires":[["5c1e5753.660f78"]]},{"id":"f5761e7.f3c03e","type":"inject","z":"c3525ae7.a368a8","name":"display an R and color the corners","topic":"","payload":"R\\n0,0,red,0,7,#00ff00,7,7,yellow,7,0,0,0,255","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":200,"y":240,"wires":[["da53dcd.f9aa2a"]]},{"id":"da53dcd.f9aa2a","type":"rpi-sensehat out","z":"c3525ae7.a368a8","name":"","x":470,"y":240,"wires":[]},{"id":"e9664a98.d0b4c8","type":"inject","z":"c3525ae7.a368a8","name":"1) display the character 'R'","topic":"","payload":"R","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":170,"y":100,"wires":[["5c1e5753.660f78"]]},{"id":"9d757ff4.713ec","type":"comment","z":"c3525ae7.a368a8","name":"If you display a single letter and then color the corners it works/","info":"","x":290,"y":60,"wires":[]},{"id":"2941dc48.9acb5c","type":"comment","z":"c3525ae7.a368a8","name":"Combining the two does not work.","info":"","x":180,"y":200,"wires":[]},{"id":"5c1e5753.660f78","type":"rpi-sensehat out","z":"c3525ae7.a368a8","name":"","x":470,"y":120,"wires":[]}]`

How are you including the `\n` in the string? If it is by the Inject node or Change node, for example, then they don’t know about escaped strings and will include a literal `\n` not a new-line character.

Try using a Function node to generate the payload with the `\n` in and you should see it work.

Ahhh I just saw this at the end of the inject node's 'Node Help:

> Note: To include a newline in a string you must use a Function node to create the payload.

I'll add this tidbit to the DOCUP thread and create a PR for it.
