hey guys, i’m new to the sonoff pow and need help with calibrating it.
can someone tell me how to calibrate tasmota so it measures the correct values?

@myle You are the man…WORKS!!! THANKS!!!

See https://github.com/arendst/Sonoff-Tasmota/wiki/Sonoff-Pow#calibration

Wire it up to a ,60 w light and see what what u get

25

You need an incandescent bulb (traditional or halogen) to avoid influences from the power factor.

26

Any idea on how to get Power Factor to show up in Hassio, This doesn’t seem to work

  • platform: mqtt
    name: “Power Factor”
    state_topic: “stat/pow1/STATUS8”
    value_template: “{{ value_json[‘StatusPWR’].Factor }}”
27

This is my configuration:

- platform: mqtt
    name: "Sonoff_PowerFactor"
    state_topic: "tele/sonoffpow/SENSOR"
    value_template: '{{ value_json["ENERGY"]["Factor"] }}'

Thanks! That did the trick!

For those who wanted the mqtt sensor attribute to display correctly. You can use this.

Basically, it read the SENSOR ENERGY and republish as SENSOR_DATA so the mqtt sensor can reach from SENSOR_DATA with all the attribute.

sensor:
  - platform: mqtt
    name: "SonOffPow1"
    state_topic: "tele/sonoffpow1/SENSOR_DATA"
    value_template: '{{ value_json.Power }}'
    unit_of_measurement: "Watts" 
    json_attributes:
      - Current
      - Today
      - Yesterday
      - Voltage
      - Total

Automation:
    - alias: 'AutoSonoffPowAtribute'
      initial_state: true
      #hide_entity: True
      trigger:
        - platform: mqtt
          topic: 'tele/sonoffpow1/SENSOR'
      action:
        - service: mqtt.publish
          data_template:
            topic: 'tele/sonoffpow1/SENSOR_DATA'
            payload: '{{ trigger.payload_json.ENERGY | tojson }}'

YES here is mine

  • platform: mqtt
    name: “POW Current”
    state_topic: “tele/sonoff_pool_pump/SENSOR”
    value_template: “{{ value_json[‘ENERGY’].Current }}”
    unit_of_measurement: ‘amps’
  • platform: mqtt
    name: “POW Power”
    state_topic: “tele/sonoff_pool_pump/SENSOR”
    value_template: “{{ value_json[‘ENERGY’].Power }}”
    unit_of_measurement: ‘watts’
  • platform: mqtt
    name: “POW Voltage”
    state_topic: “tele/sonoff_pool_pump/SENSOR”
    value_template: “{{ value_json[‘ENERGY’].Voltage }}”
    unit_of_measurement: ‘volts’

Hay bro Can you format it its easyer to read

Good afternoon,
first of all thank you for all the useful information shared on this forum.
This is the first time I write here, I hope my post will be ok.
I have a small issue with sonoff plugs (flashed with tasmota). I was trying to collect data over time in order to calculate the overall energy consumption and costs. The problem is that the total energy sensor behaviour is strange since it is not monotonus (always increasing), as you can see in the attached picture. Maybe this is due to some wifi signal drop, since the wifi signal shows drops at the position of the total energy drop. Maybe I missed some useful information concerning this. Anyway do you have some advises in order to solve this problem? Thank you

Here is the full JSON what you get back from Tasmota 8.3.1 an Sonoff POW R1

{
    "Time": "2020-05-27T20:17:30",
    "ENERGY": {
        "TotalStartTime": "2020-05-27T18:51:48",
        "Total": 0.226,
        "Yesterday": 0,
        "Today": 0.226,
        "Period": 1,
        "Power": 277,
        "ApparentPower": 277,
        "ReactivePower": 0,
        "Factor": 1,
        "Voltage": 218,
        "Current": 1.272
    }
}

therefore only replace the xxxxx to get all 11 parameters
for example also TotalStartTime

value_template: '{{ value_json["ENERGY"]["xxxxx"] }}'

btw you can get this JSON output in the HA menu:

Developer Tool > MQTT > Listen to a topic > and enter your topic like
tele/YOUR-TASMOTA-NAME/SENSOR

YOUR-TASMOTA-NAME == what you entered in your tasmota configuration for MQTT
