OpenWeather is a platform that defines itself as a "scientific yet simple approach to the weather forecast. Free. No ads.".

You can visit the official website >

In this blog post, we are going to use the openweathermap Node-RED node: node-red-node-openweathermap, which polls openweathermap.org for current weather data when an input is received.

To install it, you can either go to the Menu > Manage Palette > Install > Type: node-red-node-openweathermap and click on Install.

Or you can also go to the .node-red/ directory and install the nodes from there:

cd /home/$USER/.node-red

npm install node-red-node-openweathermap

Drop it to the Node-RED flow and double-click to edit it. You will see that the first parameter is the API key. Go to the OpenWeather's website >>>, login, and generate a new API key.

Once is validated (it can take between 10 minutes and 2 hours after the successful registration), paste the API key in the node.

Finally, in the location, you can choose either "City, Country" or "Coordinates". Select the option that fits you better. Now:

1. Add an inject node
2. Connect it to the openweathermap node
3. Add a debug node

And see all the information that you receive!

From there, link the msg.payload with the dashboard nodes, and display the widgets with the weather information as you like. For example:

Add a gauge node. 
Type: Donut. 
Label: Humidity.
Value format: {{payload.humidity}}
Units: %
Range: min:0, max:100

Get the output from the openweathermap node and connect it to this gauge node. 

Do the same with the rest of the parameters, and create an incredible Dashboard based on the data from OpenWeather!

Now, copy this flows.json below, go to the Node-RED menu, click on Import > Paste this JSON, click on Done. And compare our Node-RED Dashboard with yours!
