influx db (https://www.influxdata.com/) is a perfect database to collect my data. timestamps optmizied for queries at iot.

First create a volume to store safely the data you want to collect:

i missnamed this volume to another name, but you can change it to a good one.

then get a new container, i just pulled the latest image: influxdb:latest

after its deployment you can setup the webinterface

remember organisation name and bucket name .. we will need that later

navigate to data → api tokens and copy that token, we will need it in iobroker.
