Wrong scaler applied in SML parser

[micw]

The problem

I'm using the SML component as described in the docs. I have defined the following sensor:

sensor:
  - platform: sml
    sml_id: sml0
    name: "powerTotal"
    obis_code: "1-0:16.7.0"
    unit_of_measurement: W
    accuracy_decimals: 2
    device_class: energy
#    filters:
#      - multiply: 0.01

The problem is that I have to enable the scaler (0.01) but the meter already sends in Watt. So no scaler should be needed here.

Which version of ESPHome has the issue?

Still an issue.

I digged a bit deeper, the issue is in SmlSensor.c. Thing is that obis_info.scaler is just ignored.
