WLAN Power Outlet gives too high values (x10)

Configuration
1

Hi,
i just got 3 WLAN Power Outlets at Amazonwich can also measure voltage,current and power.
In the Smart-Life App the Values are ok, but in Tuya IOT Platform there are values 10times so high!
My TV and Sky Receiver in Standby taken 388W instead of 38.8W!
The Device-Logs in Tuya IOT Platform saying the same! 2400Volts … The Source is marked as “from Device itself”

Can anyone help me setting this up or is there a possibility to divide by 10 in Homeassistant?

i have setup a template wich gives me the right values:

sensor:
- platform: template
  sensors:
    tv_sky_power_kor:
      value_template: "{{ states('sensor.tv_sky_power')|float / 10 }}"
  sensors:
    kuhlschrank_power_kor:
      value_template: "{{ states('sensor.kuhlschrank_power')|float / 10 }}"
  sensors:
    klaranlage_power_kor:
      value_template: "{{ states('sensor.klaranlage_power')|float / 10 }}"

Well, even the Template help gives me the right things, i don`t get the sensors into HA!
in my configruation.yaml is:

sensor:
  - platform: template
    sensors:
      klaranlage_power_kor:
        name: "Klaeranlage Power"
        value_template: "{{ states('sensor.klaranlage_power') | float / 10}}"

  - platform: template
    sensors:
      tv_sky_power_kor:
        name: "TV-SKY Power"
        value_template: "{{ states('sensor.tv_sky_power') | float / 10}}"

  - platform: template
    sensors:
      kuhlschrank_power_kor:
        name: "Kühlschrank Power"
        value_template: "{{ states('sensor.kuhlschrank_power') | float / 10}}"

so for my believe the sensor.kuhlschrank_power is divided by 10 and the value is stored in kuhlschrank_power_kor right?
but i can’t find this: kuhlschrank_power_kor in HA!

i have a similar template wich works:

  - platform: template
    sensors:
      pool_wasser_temp1:
        friendly_name: "POOL Wasser Temp 1 cal"
        value_template: "{{ states('sensor.tempsensor_1') | float - 5.2}}"
        device_class: temperature
        unit_of_measurement: '°C'

here i can see the sensor pool_wasser_temp1 !

this is the result of the development-template editor:

sensor:
- platform: template
  sensors:
    entity_id: tv_sky_power_kor:
      value_template: "42.0"
- platform: template
  sensors:
    kuhlschrank_power_kor:
      value_template: "110.9"
- platform: template
  sensors:
    klaranlage_power_kor:
      value_template: "0.0"

Where is my mistake?

i’ve got it!

name: "Klaeranlage Power"

is wrong, must be

friendly_name: "Klaeranlage Power"

Just two comments:

Tuya internally uses several parameters (scale and step) to tell apps and integrations how to interpret sensor values. The official Tuya integration should take care of all this, but I remember that there have been issues in the past where devices were not following the official guidelines. When you download the diagnostics file for your integration you can actually look at those parameters.

You could simplify your template syntax. The recommended syntax is:

template:
  - sensor:
      - name: "Klaeranlage Power"
        state: "{{ states('sensor.klaranlage_power') | float / 10}}"
      - name: "TV-SKY Power"
        state: "{{ states('sensor.tv_sky_power') | float / 10}}"
      ...
