ESPHome

I’m using a Dallas sensor to measure the temperature in a room and want to get the sensor update interval value the ESPhome web interface.
The web interface looks like this:

For that I use the following code:

number:
  - platform: template
    id: select_sensor_update_time
    name: "Sensor update time (s)"
    optimistic: true
    mode: box
    min_value: '10'
    max_value: '300'
    step: '10'
    restore_value: yes
    initial_value: '30'
    on_value:
      then:
        - logger.log:
            format: "Chosen option: %s "
            args: ["x.c_str()"]

Next I want the use this value the set the sensor update_interval but I can find a way to use the value appended with ‘s’. Is there a way to get this done?
