How to template more or less a value with is_states or is_number?

Configuration
1

Trying to do a math calculation in a template sensor only if another criteria is met.

Similar to this, but the >1000 doesn’t do anything:

"{% if is_number('sensor.three') >1000 %}{{ states('sensor.one') + states('sensor.two') }}{% else %}0{% endif %}"

If sensor.three is above 1000, then is should calculate sensor.one+sensor.two.
Otherwise set to 0.

is_number is a boolean operation to check if an entity is an integer or float. Use states and convert to int to perform the operation.

states('sensor.three')|int >1000

if states('sensor.three') | float > 1000

is_number(…) returns True or False, if the state is numeric, but does not return the state‘s value as number.

Hi
I’m trying to do something similar, but with no luck.
Can someone help me with this code?
What I want is to return 0 if (inv1 + inv2) returns “unavailable”.

  - sensor:
      - name: "Total Watt Produksjon"
        unit_of_measurement: "W"
        state: >
          {% set inv1 = states('sensor.solisL.active_power') | float %}
          {% set inv2 = states('sensor.solisH.active_power') | float %}
          {% set inv3 = (inv1 + inv2) %}
          {% if states('inv3') | float > 1 %}
            {{ inv3 | round(0) }}
          {% else %}
            {{ 0 }}
8 
{{ iif ( not is_number ( inv1 ) and not is_number ( inv2 ) , 0 , 1 )  }}

Like this?

state: >
          {% set inv1 = states('sensor.solisL.active_power') | float %}
          {% set inv2 = states('sensor.solisH.active_power') | float %}
          {{ iif ( not is_number ( inv1 ) and not is_number ( inv2 ) , 0 , 1 )  }}

I’m not sure what you are trying to do? but I think you want

state: >
          {% set inv1 = states('sensor.solisL.active_power') | float %}
          {% set inv2 = states('sensor.solisH.active_power') | float %}
          {% set inv3 = iif (is_number (inv1 + inv1) , inv1 + inv1 , 0) %}
