How to reset a rotary encoder on another GPIO input - ESPHOME

ESPHome
1

Can someone help me?
I want to reset the rotary encoder value in ESPHOME when another entity has a vertain value.
Purpose is to set the rotary encoder value to 0 when an endstop, measured with reed relais on GPIO34 is shown with state “closed”.
I tried the presented method, but I receive the error “mapping values are not allowed here”
Here is the snipped of my yaml file:

binary_sensor:
  

    platform: gpio
      pin: GPIO34
      name: "GS Input DPIO34"
      id: GS_Input_GPIO34
      device_class: door
      on_value_range:
        above 0.5
            below 1.5
            then
            sensor.rotary_encoder.set_value: 
                id: GS_Rotary_Encoder
                value: 0
        platform: gpio
        pin: GPIO35
        name: "GS Input DPIO35"
        id: GS_Input_GPIO35
        device_class: door


sensor:
  

    platform: rotary_encoder
      name: "GS Rotary Encoder"
      id: GS_Rotary_Encoder
      pin_a: GPIO13
      pin_b: GPIO14
      on_clockwise:
        logger.log: "Turned Clockwise"
        on_anticlockwise:
            logger.log: "Turned Anticlockwise"
        filters:
            or:
                throttle: 30s
                delta: 10

Your’re missing some colons : and your indentation is way off.

      on_value_range:
        - above: 0.5
          below: 1.5
          then:
            - sensor.rotary_encoder.set_value: 
                id: GS_Rotary_Encoder
                value: 0

Also I think you may have your values back to front and you possibly want to OR them rather than ANDing a range. Though I don’t know for sure:

      on_value_range:
        - above: 1.5 # reset above top end stop
          then:
            - sensor.rotary_encoder.set_value: 
                id: GS_Rotary_Encoder
                value: 0
        - below: 0.5 # or reset below bottom end stop
          then:
            - sensor.rotary_encoder.set_value: 
                id: GS_Rotary_Encoder
                value: 0

The way you have it the encoder will reset if the value is between 0.5 and 1.5, not outside that range which is what the second version will do, reset if outside 0.5 to 1.5. However 0 is below 0.5 so that makes no sense.

If you want to confine it to the range 0.5 to 1.5 do this:

      on_value_range:
        - above: 1.5 # reset above top end stop
          then:
            - sensor.rotary_encoder.set_value: 
                id: GS_Rotary_Encoder
                value: 1.5
        - below: 0.5 # or reset below bottom end stop
          then:
            - sensor.rotary_encoder.set_value: 
                id: GS_Rotary_Encoder
                value: 0.5

Many thanks for the fast reply.
Ideally I want to reset the rotary encoder when the binary input (GPIO) value changes from CLOSED to OPEN to avoid resetting in loop while in a certain value range.

I assume OPEN equals 0 and CLOSED equals 1 (?) or vice versa.
So in pseudo code:

if GPIO changes from 0 to 1 then rotaryencoder = 0

Is this also possible?

Oh right. Binary sensors do not have an “on value range” action.

That depends entirely on how you have connected it. As you have not inverted the input I’m going to assume Open is 1 (on / pressed) and Closed is 0 (off / released).

So you will have to do this. It triggers when the door opens and then checks the encoder value in a condition, if it passes the condition then the encoder is reset.

    platform: gpio
      pin: GPIO34
      name: "GS Input DPIO34"
      id: GS_Input_GPIO34
      device_class: door
      on_press:  # change from  logic 0 to 1, "on_release" is logic 1 to 0
        then: 
          - if:
              condition: 
                - sensor_in_range:
                    id: GS_Rotary_Encoder
                    above: 0.5
                    below: 1.5
              then:
                - sensor.rotary_encoder.set_value: 
                    id: GS_Rotary_Encoder
                    value: 0

Many thanks. I can work with that - I understand now how to do this.
Actually you’ve posted a more complex solution than I needed …
So my solution simply looks like:

binary_sensor:
  - platform: gpio
    pin: GPIO34
    name: "GS Input DPIO34"
    id: GS_Input_GPIO34
    device_class: door
    on_release:  # change from  logic 1 to 0, "on_press" is 0 to 1
      then: 
        - sensor.rotary_encoder.set_value: 
            id: GS_Rotary_Encoder
            value: 0

Again many thanks and have a good day.
