HowTo: Register OpenWeatherMap.org API Key

Via the service of OpenWeatherMap.org You can get free weather data. To be able to access this service in an automated way – for example from NodeRed or from an Arduino – you need an API key.

This article will describe how to register this.

Hints for our lovely english readers: Basically, many of the articles on Nerdiy.de are translations from the original german articles. Therefore, it may happen here and there that some illustrations are not available in english and that some translations are weird/strange/full of mistakes or generally totaly wrong. So if you find some obvious (or also not obvious) mistakes don't hesitate to leave us a hint about that in the comment section. 
Also please don't get confused, that instead of a "dot" often a "comma" is used as decimal separator. 🙂


Register user login for OpenWeatherMap.org

To register an API key, you must first set up a user login. Go to the website OpenWeatherMap.org.

And click on “Sign Up” in the upper area.
This will take you to a form where you can register a user account.

Register API key

Once you’ve created your user account for OpenWeatherMap, it’s time to create an API key. An API key is a long string of characters that gives you access to the services offered by OpenWeatherMap, much like a username and password.

After you have registered a user account and logged in with it, you will be directed to an overview page.
There you click on “API keys” and reach thereby the side on which new API Keys can be registered.
There you will see all API-Keys that you have already registered. In order to register a new one in the category “Create key” give a name and click on “Generate”.
Your newly registered API key will then appear in the list and can be used.

You can now use this API key in your Arduino or RaspberryPi project to retrieve current weather data.


I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂

P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you appreciate it that I share these information with you, I would be happy about a small donation to the coffee box. 🙂
