sensor for grid show only positive value, flow depend on direction (forward or reverse)

[goanes]

Hi
I really like the tool with instant power which make more sense to adopt change of consumption.

My question is my sensor are always showing positive value.
We can obviously know if it is positive or negative value depending on another entity which is direction.
If forward, that’s mean positive value I consume electricity from the grid.
If reverse, that's mean negative value, I give electricity to the grid.

Do you help me configuring that if it is possible?

Thanks

I also have a dual Tuya sensor which always displays positive values but they depend on the additional value that describes its direction. Tnx

Hi
I find the solution.

• platform: template
  sensors:
  power_a_with_negative_value:
  friendly_name: power_a_with_negative_val
  value_template: >-
  {%if states.sensor.direction_a.state == "REVERSE"%}
  {{"-"+states.sensor.power_a.state}}
  {%else%}
  {{states.sensor.power_a.state}}
  {%endif%}

to add on /homeassistant/configuration.yaml ?

[goanes]

Yes. You need to add tab to format correctly the code

[goanes]

I have created a new file sensor.yaml

- platform: template
  sensors:
    power_a_with_negative_value:
      friendly_name: power_a_with_negative_val
      value_template: >-
        {%if states.sensor.direction_a.state == "REVERSE"%}
          {{"-"+states.sensor.power_a.state}}
        {%else%}
          {{states.sensor.power_a.state}}
        {%endif%}

    power_b_with_negative_value:
      friendly_name: power_b_with_negative_val
      value_template: >-
        {%if states.sensor.direction_b.state == "REVERSE"%}
          {{"-"+states.sensor.power_b.state}}
        {%else%}
          {{states.sensor.power_b.state}}
        {%endif%}

    power_a_2_with_negative_value:
      friendly_name: power_a_2_with_negative_val
      value_template: >-
        {%if states.sensor.direction_a_2.state == "REVERSE"%}
          {{"-"+states.sensor.power_a_2.state}}
        {%else%}
          {{states.sensor.power_a_2.state}}
        {%endif%}

    power_b_2_with_negative_value:
      friendly_name: power_b_2_with_negative_val
      value_template: >-
        {%if states.sensor.direction_b_2.state == "REVERSE"%}
          {{"-"+states.sensor.power_b_2.state}}
        {%else%}
          {{states.sensor.power_b_2.state}}
        {%endif%}

and add this in the configuration.yaml
sensor: !include sensor.yaml

[goanes]

you juste need to change with the name of your sensor
in this example:

    power_a_with_negative_value:
      friendly_name: power_a_with_negative_val
      value_template: >-
        {%if states.sensor.direction_a.state == "REVERSE"%}
          {{"-"+states.sensor.power_a.state}}
        {%else%}
          {{states.sensor.power_a.state}}
        {%endif%}

my sensor name is direction_a or .power_a. Just change the name with yours

[nettunoroberto]

Can you share your configuration?

missed comma between flow collection entries (13:2)

10 | power_a_with_negative_value:
11 | friendly_name: power_a_with_nega ...
12 | value_template: >-
13 | {%if states.sensor.direction_a.s ...
-------^
14 | {{"-"+states.sensor.power_a.state}}

You can also just create a template helper and add the value_template code for each sensor.
