Added support to the integration I started (and you commented on)

Hey Shaun,

I hope you don't mind - I used your awesome work on the node-red integration shared on this repo and added in support in the integration I started. Why don't you have a look and see if there is anything you'd like to add.

Also, I added your details as attribution on the README.

All the best,

Brett
