Offset valve actuator automation

Configuration
1

Hi.
I made automation that controls the valve actuator.

platform: numeric_state
entity_id:
  - sensor.esp_kotownia_kocio
above: sensor.esp_kotownia_zasobnik_c_w_u

This part is responsible for opening the valve if the temperature:
sensor.esp_kotownia_kocio is higher than sensor.esp_kotownia_zasobnik_c_w_u.
I would like to add an offset to make the actuator work 10 degrees higher.
Simply, how to add the value 10 to the sensor.esp_kotownia_kocio entity in this configuration?
