speak text on Google Home or Chromecast

With the node-red-contrib-cast node it is possible to let the Google Home speak any text.

The documentation can be found at node-red-contrib-cast.

Example Flow:

Configure your local router to make sure that your google home device alway gets the same ip adress. Open the node "change: 2 rules" and add the the ip adresse of your google home device to msg.ip (if it is working you may delete the debug node)
