Don’t know if it helps and i am trying to keep it short… I build an Oiltank measurement system with another raspberry pi. The results will be written to a mysql database and to a JSON file, which will be uploaded to my NAS. On the NAS i run the database and a web server. To Display the results on a webpage i used this php script: https://github.com/cruunnerr/OilTank-Graph-WebPage To display the results on my MM i got some very much help from our user @doubleT He wrote this module for me: https://github.com/cruunnerr/MMM-Oiltank The module grabs the data from a JSON file and shows it on the MM. Maybe this could help :/ MagicMirror: [image: 1522492361599-bildschirmfoto-2018-03-31-um-12.30.56.png] Web Page: [image: 1522492361991-bildschirmfoto-2018-03-31-um-12.30.12-resized.png]
