Created a sensor but can't find it in the GUI

Thanks a lot @tom_l

Found my solution here

# https://www.home-assistant.io/integrations/sensor.mqtt/
 
 mqtt:
   sensor:
     - name: "Apartment Energy Meter - Total"
       unique_id: "apartment_energy_meter_total"
       state_topic: "mbus/apartment/sensors"
       value_template: "{{ value_json.sn.MeterReading.total }}"
       unit_of_measurement: "kWh"
       device_class: energy
       device:
         name: "SBC AWD3D5W10"
         identifiers: energymeterapartment
         manufacturer: SaiaBurgess
         model: AWD3D5W10
     - name: "Benito Energy Meter - Total"
       unique_id: "benito_energy_meter_total"
       state_topic: "mbus/benito/sensors"
       value_template: "{{ value_json.sn.MeterReading.total }}"
       unit_of_measurement: "kWh"
       device_class: energy
       device:
         name: "NZR DHZ 5/63"
         identifiers: energymeterbenito
         manufacturer: NZR
         model: 'NZR DHZ 5/63'

And have finally moved the above snippet to it’s own file:

 sensor: !include sensors.yaml

P.S.: for those interested: I’ve shared my NodeRed Flow in this thread.
