This is what the two template sensors look like:

- platform: template
  sensors:
    shelly_total_power_consumption:
      friendly_name: 'Verbrauch Gesamt'
      unit_of_measurement: 'kWh'
      value_template: '{{ ((float(states.sensor.shelly_shem_3_dc4f227648a6_1_total_consumption.state) + float(states.sensor.shelly_shem_3_dc4f227648a6_2_total_consumption.state) + float(states.sensor.shelly_shem_3_dc4f227648a6_3_total_consumption.state)) | round(2) )}}'
                               
- platform: template
  sensors:
    shelly_total_power:
      friendly_name: 'Leistung Gesamt'
      unit_of_measurement: 'W'
      value_template: '{{ float(states.sensor.shelly_shem_3_dc4f227648a6_1_current_consumption.state) + float(states.sensor.shelly_shem_3_dc4f227648a6_2_current_consumption.state) + float(states.sensor.shelly_shem_3_dc4f227648a6_3_current_consumption.state | round(0) )}}'

Any idea what’s wrong? Thanks!!
