Ultrasonic sensor with LED and esp32

ESPHome
1

Hi everyone. I’m new to esphome. I would like to create a tank level sensor with ultrasonic sensor. I have already configured the sensor for the liquid level in percentage by setting minimum and maximum values. now I would like for each decade to turn on an LED based on the level of the liquid (10% - 20% …) but I would also like it to turn off if the level decreases. Unfortunately I didn’t succeed. advice?

Hi Giovanni and welcome to HA. Can you edit your post as per the link below, to enclose your yaml in formatted text tags? On the posting toolbar they look like </>. Because indentation is so important in yaml you need to post it so the formatting is readable.

Assuming that the intention is to only turn the lights on and off in successive order, a relatively simple solution would be to add an action to every on_value_range action to turn off the adjacent lights first and then turn on the intended light.
Something like this:

    on_value_range:
      - above: 0
        below: 11
        then:
          - light.turn_off:
              id: led20p
          - light.turn_on:
              id: led10p
      - above: 12
        below: 21
        then:
          - light.turn_off:
              id: led10p
          - light.turn_off:
              id: led30p
          - light.turn_on:
              id: led20p
      - above: 22
        below: 31
        then:
          - light.turn_off:
              id: led20p
          - light.turn_off:
              id: led40p
          - light.turn_on:
              id: led30p

Etcetera.

Please note that I corrected some indentations in your code: each indentation in Yaml should consist of 2 spaces.
