Help with simple template that check a sensor for a value and does an IF ELSE

Configuration
1

Hi,

I have 3 sensors. What I want to achieve is simple. If A = 0 then C - B is my final value else C + A is the final value. I have come up the code below but it’s clearly wrong. Any help would be appreciated.

- name : "active_energy_usage"
    unit_of_measurement: 'W'
    device_class: power
    state_class: measurement
    state: >
    {% if has_value(sensor.powerpalble_powerpal_000491c1', 0) -%}
          {{ [0, states('sensor.inverter_active_power') | round - states('sensor.pv_grid_return') | round] | max }}
    {%- else -%}
          {{ [0, states('sensor.inverter_active_power') | round + states('sensor.powerpalble_powerpal_000491c1') | round] | max }}
    {%- endif %}

  - name: Active energy usage
    unique_id: active_energy_usage
    unit_of_measurement: 'W'
    device_class: power
    state_class: measurement
    state: >
      {% set pwrpal = states('sensor.powerpalble_powerpal_000491c1') | round(0) %}
      {% set inverter = states('sensor.inverter_active_power') | round(0) %}
      {% set pv = states('sensor.pv_grid_return') | round(0) %}
      {{ [0, inverter - pv if pwrpal == 0 else inverter + pwrpal] | max }}

You can test the template by copy-pasting it (4 lines) into the Template Editor.

Thanks Taras. One more question if you will please. I have one more issue if you can help. I would like to return a 0 value for PV sensor irrespective of its value is if PWRPAL reads anything above 0.

Can you help?

If this is what you want:

      {% set pv = 0 if pwrpal > 0 else pv %}

then you can add it just before the last line as shown here:

  - name: Active energy usage
    unique_id: active_energy_usage
    unit_of_measurement: 'W'
    device_class: power
    state_class: measurement
    state: >
      {% set pwrpal = states('sensor.powerpalble_powerpal_000491c1') | round(0) %}
      {% set inverter = states('sensor.inverter_active_power') | round(0) %}
      {% set pv = states('sensor.pv_grid_return') | round(0) %}
      {% set pv = 0 if pwrpal > 0 else pv %}
      {{ [0, inverter - pv if pwrpal == 0 else inverter + pwrpal] | max }}

@123 Thank you so much that worked a treat.
