Template error: int got invalid input 'unknown' when rendering template

Configuration
1

Hi, i have created a template sensor, that does a SUM of 2 other sensors, but upon restart when the integrations are being loaded, it takes a while before this sensor gets data : sensor.kostal_piko_current_power

Si already checked if there is a value, but still receive error below …how can i get rid of that error in my log? its only once at reboot/restart

  - name: Real Consumption
    unique_id: real_consumption
    state_class: measurement
    device_class: energy  
    unit_of_measurement: 'W'
    state: >-
      {% set val = states('sensor.kostal_piko_current_power') %}
      {% if val is defined %}
        {{ states("sensor.smappee_1006001738_local_total_consumption_active_power") | int + states("sensor.kostal_piko_current_power") | int }}
      {% else %}
        0
      {% endif %}

error:

The above exception was the direct cause of the following exception:

You have to supply a default to int

as a sidebar, val will always be defined because you define it in the previous line. Using defined checks to see if the variable exists in the templates namespace. It does not check the variables value.

You can also just add an availability template too to avoid adding defaults

    state: >
      {{ states("sensor.smappee_1006001738_local_total_consumption_active_power") | int + states("sensor.kostal_piko_current_power") | int }}
    availability: >
      {{ states("sensor.smappee_1006001738_local_total_consumption_active_power") | is_number and states("sensor.kostal_piko_current_power") | is_number }}

ok, the second one is indeed a good approach !!

I have a similar one, on startup i create water / gas sensor like below, also on start, the json is not filled yet, and receive : jinja2.exceptions.UndefinedError: None has no element 0 in log

  - name: Smappee Water Consumption
    unit_of_measurement: "L"
    state_class: total_increasing
    device_class: water
    state: >-
      {{ state_attr('sensor.smappee_water_gas', 'records')[0]["value1"] }}

Can i use here the method is used before to check if its defined or != None ?

or something like:

    state: >-
      '{% if state_attr('sensor.smappee_water_gas', 'records') %}{{ state_attr('sensor.smappee_water_gas', 'records')[0]["value1"] }}{% endif %}'
6

So the availability template overrides errors in the template now?

I know there was talk of this but wasn’t sure it was implemented yet.

Yah, been that way for at least 6 months
