About the service from OpenWeatherMap.org you can get free weather data. In order to access this service automatically - for example from NodeRed or from an Arduino - you need an API key.
This article describes how to register it.
Register user login for OpenWeatherMap.org
In order to register an API key, you must first set up a user login. Go to the website OpenWeatherMap.org.
Register API key
Once you have created your user account for OpenWeatherMap, you can now create an API key. An API key is a long string of characters that - similar to a username and password - gives you access to the services offered by OpenWeatherMap.
You can now use this API key in your Arduino or RaspberryPi project to retrieve current weather data.
Have fun with the project
I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are always welcome. 🙂
PS 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 think it's cool that I share the information with you, I would be happy about a small donation to the coffee fund. 🙂
