After some researches, I found the template sensors…
template:
- sensor:
- name: "Time heater on"
unique_id: time_heating
device_class: 'duration'
unit_of_measurement: min
state_class: total_increasing
state: >
{% if is_state('sensor.heater', 'heat') %}
{{ (as_timestamp(now()) - as_timestamp('2023-05-01T06:54:44.000Z'))/60}}
{% else %}
{{ this.state }}
{% endif %}
I dont’ know yet why, but yesterday, it seemed to work. Now, it gives me absurd results.
The dev mod gives me the result of
{{ (as_timestamp(now()) - as_timestamp(‘2023-05-01T06:54:44.000Z’))/60}}
when the heater’s state is ‘heat’
The logs give me this error
Error adding entities for domain sensor with platform template

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

well, I’m quite stucked into nowhere ![:expressionless: :expressionless:](https://community.home-assistant.io/images/emoji/twitter/expressionless.png?v=12)
if someone has any clue, I’d be glad to give it a try
thanks
