-Create an influx database via the console and add a user for access. +An Influx database is created via the console. Only the access and the name of the thank you bank need to be stored. A Python script retrieves the data from the MQTT broker and also builds the structure based on the data.

-The structure in the database is then created with a Python script, using a Json format. +

-With the help of the Python script, you can specifically query data from the broker and store it in the database in a structured way.
