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. the integration into iobroker is a little bit tricky, the current build is not able to work with influxdb2 so we have to get it manualy. switch into expert mode and install it from own url:

get a new tab for github: https://github.com/ioBroker/ioBroker.influxdb and checkout the tags from 2.4.0 and copy that url:

insert url into custom own url in iobroker

when its installed, you have to search in your adapters again and tada, you can get version 2.4.0
