HLW8012 / CSE7759: voltage_divider parameter has no effect

Operating environment/Installation (Hass.io/Docker/pip/etc.):

Unraid/Docker installation on i686 home server, with separate containers for Home assistant, MQQT, and ESPhomeyaml, all from official repos.

ESP (ESP32/ESP8266/Board/Sonoff):

Sonoff POW R1 v2 (CSE 7759 metering chip instead of HLW8012, shall be supported by Xoze Perez's library)

Affected component:

https://esphomelib.com/esphomeyaml/components/sensor/hlw8012.html

Description of problem: Voltage_diivider parameter has no effect. Can be temporary sorted out by using a multiply filter

Problem-relevant YAML-configuration entries:

sensor:
  - platform: hlw8012
    sel_pin: 5
    cf_pin: 14
    cf1_pin: 13
    #commented to clear logs

Additional information: I have not played with current_resistor parameter yet to check if it has the same behavior.
