This project demonstrates how to capture charger state data from Menneken EV Chargers using the same network interface as the mobile application. The given solution pushes the data to an MQTT topic, so another instance can persist it in a database, such as the time-series database TimescaleDB.
This is not an official Menneken project, nor I am associated with Menneken in any respect. I am just a customer who wants to be in charge of the data generated by the EV charger I paid for.
Use this at your own risk. I am not responsible for any damage or undesired operation caused by the use of this program. Do not use this application if you don't agree with that.
If you are associated with Menneken and are not comfortable with this application, please contact me so I can alter this project according to your advise. Thank you!

Listen to charger telegrams:
(app) mosquitto_sub -v -h localhost -t chargers/statusUpdate/SG1Persist incoming telegrams to database:
