Hassio - Owntracks/Battery info - Config of 2 Phones

Hi,
I am real beginner - my absolute 1st try is, to indicate the battery status of 2 mobile devices…
I am running Hassio 2.12 on a rasperry.
I have now done it to indicate 1 phone battery information via “Mosquitto broker” addon and owntracks app.
Now I thought I just copy past the block in the configuration file:

sensor:

  • platform: mqtt
    state_topic: “owntracks/Sensor/lg6”
    name: “Batterie_hdy1”
    unit_of_measurement: “%”
    value_template: ‘{{ value_json.batt }}’
    device_class: battery

sensor:

  • platform: mqtt
    state_topic: “owntracks/Sensor/hw6”
    name: “Batterie_hdy2”
    unit_of_measurement: “%”
    value_template: ‘{{ value_json.batt }}’
    device_class: battery

This seems not to work.
Both log in via same user “Sensor”
Can I use the same user/password ?

Any hints what to change?

Regards,
Jörg
