Sonoff pow R2 sensors

Hello, I have sonoff pow R2 switch. I configured it in the home assistant configuration.yaml:

switch:
  - platform: mqtt
    name: Boiler
    command_topic: "cmnd/sonoff/power"
    state_topic: "stat/sonoff/POWER"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: true

Today I wanted to monitor the power, current and voltage of the Switch in the home assistant so I added this to the configuration.yaml in the sensor section:

sensor:
 - platform: mqtt
    name: "Boiler Current"
    state_topic: "tele/sonoff/SENSOR"
    value_template: "{{ value_json['ENERGY'].Current }}"
    unit_of_measurement: 'A'
  - platform: mqtt
    name: "Boiler Power"
    state_topic: "tele/sonoff/SENSOR"
    value_template: "{{ value_json['ENERGY'].Power }}"
    unit_of_measurement: 'W'
  - platform: mqtt
    name: "Boiler Voltage"
    state_topic: "tele/sonoff/SENSOR"
    value_template: "{{ value_json['ENERGY'].Voltage }}"
    unit_of_measurement: 'V'

I restated the home assistant and turned on the switch and It turend on I checked that the boiler is working. I waited a few minutes and it show me everthing is 0 in the sensors and doesn’t change. I entered to the web interface of the switch and also there it shows 0 in all the parameters of the sensor.
What is the problem?

Are you sure you have the device configured correctly (as a sonoff pow r2)?

Yes. Here is a picture:

Perhaps it’s just from copy and paste but the indentation appears incorrect from the Boiler Current line onwards.

Also double check the state topic on the sonoff WebUI

it’s how it looks in the file configuration.yaml:
Capture1
Capture2

Is the inderntation ok?

And it’s the state topic from the webUI:

Is this good?
