I just received my first bulb, and couldn't find a node for it. So i used the information i found in the excellent node.js library https://www.npmjs.com/package/tplink-lightbulb to write a simple function for it.
This version also returns the status message from the bulb after setting it.

Hi, this flow was exactly what I was looking for. I am getting an error though "SyntaxError: Unexpected token � in JSON at position 0" returned from the bulb (LB120) was wondering if you had any thoughts on this? I am getting intermittent operation when using the flow.
Thanks
