With NodeRed or the appropriate nodes, you can very easily retrieve data from the Internet and display it in a processed form.<\/p>\n\n\n\n

A practical application for this is, for example, calling up gas station prices from the area and automatically displaying them in a table. The web service Tankerkoenig.de is kind enough to offer its data free of charge via its API. <\/p>\n\n\n\n

With the NodeRed code below and an API code from Tankerkoenig.de you can easily keep up to date with the current gas station prices. For this purpose, the data is called up regularly and clearly displayed in a table on the dashboard.<\/p>\n\n\n\n

Everything you need for the implementation is described in the following article.<\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>
