Help with power template

Configuration
1

Hi, I am hoping for some help.

I have created a template to take readings from a sensor which ignores all positive value and when it goes negative I want to record the value and make it in to a positive number (this will be live power going back in to the grid)

How i have it now it responds unavailable, the input sensor is ok and reading fine

here is my template

  - platform: template
    sensors:
      solar_power_exported:
        friendly_name: "Solar Power Exported"
        unique_id: solar_power_exported
        unit_of_measurement: W
        value_template: >
          {% if (state('sensor.power_solar_difference') < 0) %}
            {{ abs(state('sensor.power_solar_difference') | float) }}  # Convert to float
          {% else %}
            0
          {% endif %}

I used AI to generate it as I wasn’t sure on where to start.

Thanks

Remove this:

# Convert to float

It’s being handled as a literal string and not a comment. As a result, the value isn’t a number and unit_of_measurement requires a number to report it in Watts.

Thanks

but I still get Unavailable

            {{ abs(state('sensor.power_solar_difference') | float) }}
          {% else %}
            0
          {% endif %}

On closer inspection, I found more errors created by whatever AI tool you had used, such as calling the states() function state() and not supplying float() with a default value.

- platform: template
    sensors:
      solar_power_exported:
        friendly_name: "Solar Power Exported"
        unique_id: solar_power_exported
        unit_of_measurement: W
        value_template: >
          {% set psd = states('sensor.power_solar_difference') | float(0) %}
          {{ psd | abs if psd < 0 else 0 }}

Thank you so much, its working :smiley:
