A Node-RED node to send local popup notifications.
Uses Growl
Run the following command in your Node-RED user directory - typically ~/.node-red
npm install node-red-node-notify
Uses Growl so should work cross platform but will need pre-reqs installed... see this link for detailed instructions.
If installing on Windows you MUST read the install instructions ... especially the bit about adding growlnotify to your path... or it WILL NOT work.
Uses Growl to push the msg.payload to the local desktop.
The title can be set by msg.topic.
