This flow will look for specific twitter hashtags and will flash a Philips Hue lamp once when a hashtag is detected. It requires the hue node (you need to have installed node-red-nodes and the node-hue-api module) and a valid Hue access token.
It is a simple flow that also demonstrates how to set parameters on the Hue node using the message input.
