One entity change positive/negative a second entity value

Hi All

I’m really struglling coding

I have a smart sensor bidirectional elecricity
This sensor has 2 entity:

  • Current Load: Watt of electricity
  • Flow of the current: Reverse or Forward

I didn’t find a way to integrate this sensor into my energy calculation

I would like to set up Grid flow: Negative if entity flow is “Reverse”; Positive if it is “Forward”

I create this code:

sensors:
      friendly_name: Consumo Totale Casa
      unit_of_measurement: 'W'
      device_class: Energy
    {{ if (states('sensor.flusso') "reverse" ) }}
          value_template: "{{ -1 * (states('sensor.consumo_pinza')| float (0) }}"
          unit_of_measurement: "W"
        {{ else }}
          value_template: "{{ (states('sensor.consumo_pinza')| float * 1) | int }}"
          unit_of_measurement: "W"
        {{ endif }}

It give me error into code but I do not know what is wrong

Thank you

You can’t use use a Jinja2 template to control which YAML options are used in the configuration.

A Jinja2 template can only be used to compute the value of a YAML option.

    sensors:
      friendly_name: Consumo Totale Casa
      unit_of_measurement: 'W'
      device_class: energy
      value_template: >
        {{ states('sensor.consumo_pinza') | float(0) * iif(is_state('sensor.flusso', 'reverse'), -1, 1) }}

Thank you for your answer

Using your code Now I get this:

Value is positive and it is correct
So now entity shows Forward (means I get power from the grid) and it is correct to be positive value

I’ve tried to change to “forward” in code, just to check if value become negative, but it does not

I believe that’s how you want it to work, yes? Negative when ‘reverse’ and positive when ‘forward’.

I understood why!

The “REVERSE” or “FORWARD” text message from sensor is all capital letters.
Written in small letter, was not working reporting only “no” values

thank you so much!
