ESP8266 Shelly Plug EU - no voltage and current

ESPHome

Hello,

I am new to ESPHome. I have a device called “Shelly Plug” in EU version. Acc. my understanding this is also is called “Shelly Plug 2” and ESP8266 based. I installed ESPHome as described here:
https://devices.esphome.io/devices/Shelly-Plug2

Unfortunately I only get power and energy. I do not get values for voltage and current. Any idea?

esphome:
  name: ${devicename}
  platform: ESP8266
  board: esp8285

sensor:
  - platform: hlw8012
    sel_pin: GPIO1 # not connected
    cf_pin: GPIO5
    cf1_pin: GPIO3 # not connected
    current:
      name: "current"
      id: current
      unit_of_measurement: "A"
      accuracy_decimals: 3
    voltage:
      name: "voltage"
      id: voltage
      unit_of_measurement: "V"
      accuracy_decimals: 1
    power:
      name: "power"
      id: power
      unit_of_measurement: "W"
      accuracy_decimals: 0
    update_interval: 10s

  - platform: total_daily_energy
    name: "energy"
    power_id: power
    filters:
      - multiply: 0.001
    unit_of_measurement: kWh

It looks like I found the answer to my question by myself: The device just cannot provide these values.

I do not have a reference where this clearly is stated. But this is my conclusion after consulting several information I found.
