Modbus integration mit packages

Hello,
I’m currently trying out HA and would like to integrate devices via Modbus.
To do this, I changed the configuration.yaml:


# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

homeassistant:
  packages: !include_dir_named packages


Then added the folder “pachages” and in it e.g. sma.yaml

modbus:
  name: sma
  type: tcp
  host: 192.168.115.25
  port: 502
  sensors:
    - name: PV-Leistung
      unit_of_measurement: W
      slave: 3
      address: 30775
      count: 2
      data_type: uint32

But I get the following error message:

Home Assistant Core

Invalid config for 'modbus' at packages/sma.yaml, line 7: PV-Leistung: `count` illegal with `data_type: uint32` 'modbus->0->sensors->0', got {'name': 'PV-Leistung', 'unit_of_measurement': 'W', 'slave': 3, 'address': 30775, 'count': 2, 'data_type': 'uint32', 'scan_interval': 15}, please check the docs at https://www.home-assistant.io/integrations/modbus
