Number component continuously transmits duplicate values.

The problem

The base number component will transmit duplicate values on each update interval. This can be improved with lambda filter, however, if using the number modbus component, every update_interval all the numbers on the range will be updated, and lambda can not be used to filter out duplicate readings.

Example YAML snippet

- platform: modbus_controller
    use_write_multiple: true
    modbus_controller_id: ${modbus_controller_id}
    id: volt_Time_point_1_bc_limit
    name: "${name} Volt Time point 1 Batt Charge Limit"
    unit_of_measurement: "V"
    device_class: voltage
    address: 160
    min_value: 44
    max_value: 58
    mode: box
    step: 0.1
    value_type: U_WORD
    lambda: |-
      static float prev;
      if (x * 0.01 == prev) return {};
      return prev = x * 0.01;
    write_lambda: |-
      return x * 100;
    disabled_by_default: true
    skip_updates: ${skip_updates13}
    force_new_range: true

The above will report unfiltered modbus read (without the multiplication) on each update_interval.

Anything in the logs that might be useful for us?
