Template sensor does not work

[nebbiadigiorno (nebbia)]

Hi all, i have this template-sensor that suddenly has stopped working.
Any ideas?

  - platform: template
    sensors:
      batteria_macchina_da_ricaricare:
        friendly_name: "Batteria da caricare"
        unit_of_measurement: 'kWh'
        value_template: >
          {% set percent_desired = states('input_number.batteria_desiderata') | int %}
          {% set percent_current = states('sensor.i4_edrive40_percentuale_di_batteria_rimanente') | int %}
          {% set battery_capacity = 80.3 %}
          {% set battery_to_charge = (battery_capacity * (percent_desired/100)) - (battery_capacity * (percent_current/100)) %}
          {{ '%0.1f'|format(battery_to_charge) }}

Looks good to me still: it’s legacy format but that still works.

Are you certain your two source entities are still working? Do you have anything in the logs? You don’t provide a default value to the int filters, so they will throw an error if the input isn’t a number.

the template works, so the entity.

but not the sensor:

Perhaps an error elsewhere in the YAML file has broken this one? Check the logs.

It’s including your comment as part of the template output. Remove that comment.

[nebbiadigiorno (nebbia)]

OMG, thanks a lot!!

[TheFes]

If you want to include comments in your templates:

{# this is a comment in jinja #}

[nebbiadigiorno (nebbia)]

nope, it was the comment for the second sensor

[TheFes]

oh right, that comment wasn’t indented properly
