Check Battery Level for Door Sensors

Configuration

Hi,

I have about 8 door sensors.

I would like to run a script every day at specific time to check the battery level of all door sensors, if the battery level under specific threshold, it should call a service to send me sms message.

I have created the below script.

I am getting this error when running the script:

“Failed to call service script/test. Error rendering data template: TemplateRuntimeError: cannot assign attribute on non-namespace object”

Anyone can help?

alias: Battery Level Check
sequence:
{%- for entity_id in ( states.binary_sensor | map(attribute=‘entity_id’)) -%}
{%- if (state_attr(entity_id,‘battery_level’) | int < 2) -%}
{%- if (state_attr(entity_id,‘battery_level’) != None) -%}

  • service: input_text.set_value
    target:
    entity_id: input_text.sms_message
    data:
    value: {{ state_attr(entity_id,‘friendly_name’) }} Battery Level {{ state_attr(entity_id,‘battery_level’) }}
  • service: rest_command.sms_battery_low_message
    {% endif -%}
    {% endif -%}
    {%- endfor -%}
    mode: single

Please see the sticky post - particularly section 11 on formatting code.

Many thanks.
I have no issue with formatting.
Somehow, the format was modified when posted this topic.

Because you didn’t use code markup, which is explained in that sticky post.
