    - add txt writer
    - use containerized Postgres
    - use contenerized Mongo
    - add Mongo Writer
    - cli commands (and mqtt-hook) to replay parts of the raw data back into Queue (from, to, topic)
    -       (all at once, synced, fast forward)
    so I can make a button "replay last hour/day" in IoT OnOff

    - save the secrets somewhere

    - try to use a free HiveMQ queue
