HA Errors for some registers

I'm seeing some HA errors in my logs for registers that don't have the correct Device Class etc. What should I be using where the value is not something that would fit in the device class options?

Here "Battery Status" is either 0 or 1 and doesn't have a unit as set in my register:

- name: battery_status
  description: Battery Status
  unit:
  active: true
  modbus:
    register: 33135
    read_type: register
    number_of_decimals: 0
    function_code: 4
    signed: false
  homeassistant:
    device: number
    min: 0
    max: 1
    step: 1

The above produces the following error in HA:

2022-12-30 22:43:07.186 ERROR (MainThread) [homeassistant.util.logging] Exception in async_discover when dispatching 'mqtt_discovery_new_sensor_mqtt': ({'name': 'Battery Status', 'state_topic': 'solis2mqtt/battery_status', 'unique_id': 'solis2mqtt/battery_status', 'device_class': None, 'state_class': 'measurement', 'unit_of_measurement': None, 'device': {'name': 'solis2mqtt', 'model': 'solis2mqtt', 'manufacturer': 'Ginlong Technologies', 'identifiers': 'solis2mqtt', 'sw_version': 'solis2mqtt 0.7'}, 'platform': 'mqtt'},)

The same is true for "Storage Mode", typically 35 / 33:

# Battery storage mode, 33=self use, 35=timed charge
- name: storage_mode
  description: Storage Mode
  unit:
  active: true
  modbus:
    register: 43110
    read_type: register
    number_of_decimals: 0
    function_code: 3
    signed: false
  homeassistant:
    device: number
    min: 33
    max: 35
    step: 1

Generates error:

Could anyone advise what changes are needed to the registers to clear the above errors pleasE?
