A simple Node-RED node that gets the forecast data from forecast.io. To get this data you need to supply your API key (more information here: https://developer.forecast.io). It is free of charge until 1.000 requests/day.
Run the following command in the root directory of your Node-RED install
npm install node-red-contrib-forecast
A simple flow that gets the forecast data and uses the Template function to show the data:
