The template i am using is this:

Where i am wrong?

Start with defining a default value for a conversion to a number:

states() | int(default=…)

Otherwise if a state is unknown - you will get an error.

3

The sensor does not have a value int can convert into a number. You need to supply a default in this case. If you supply a number > 100 it will use your unknown icon. I chose 105

{% set bl = states('sensor.oppo_battery_level') | int(105) %}

Thanks to both @Ildar_Gabdullin @tom_l , but non being so expert with templates, can you post here the correct template?

5

I just did. Change your template to use this:

All you need to add is the (105) part to your existing template.

I take advantage of your expertise to try to resolve this error in another template.
The error is:

2024-11-06 12:00:46.011 ERROR (MainThread) [homeassistant.helpers.event] Error while processing template: Template<template=({% if (state_attr('sensor.fha_place', 'direction_of_travel') == 'stationary') and (state_attr('sensor.fha_place','home_zone') == 'zone.home') %} Fha è a Casa {% elif (state_attr('sensor.fha_place', 'direction_of_travel') == 'stationary') and (state_attr('sensor.fha_place','home_zone') !== 'zone.home')%} Fha is Here:               {% else %} Fha sta {% endif %}) renders=50>

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

    raise TemplateError(err) from err
homeassistant.exceptions.TemplateError: TemplateSyntaxError: unexpected '='

And the template is:

                  {% if (state_attr('sensor.fha_place', 'direction_of_travel')
                  == 'stationary') and
                  (state_attr('sensor.fha_place','home_zone') == 'zone.home') %}
                  Fha è a Casa {% elif (state_attr('sensor.fha_place',
                  'direction_of_travel') == 'stationary') and
                  (state_attr('sensor.fha_place','home_zone') !== 'zone.home')%}
                  Fha is Here:               {% else %} Fha sta {% endif %}

Thanks for the support… can you give me a hint also for the other template error i posted here?
