Third Trigger on_stop for Rotary Encoders

[Pippowicz]

Describe the problem you have/What new integration you would like

There is an on_clockwise and on_anticlockwise trigger for the rotary encoder. It would be nice to implement a third one: on_stop.

Please describe your use case for this integration and alternatives you've tried:

For my Garage Door i want to get state opening or closing. That works with the current setup. Whats missing is a third one which triggers when no movement is happening on the encoder. This would result in a third possible state: stopped.

The current Implementation gives back the last movement state.

Additional context Perhaps it would be needed to also set a time to wait for stop to trigger.

Accoding to the Docs these triggers trigger on every step. So the triggers are not really used to indicate is moving, but just the increment it has stepped. As such I do not think an on_stop trigger makes much sense.

I've modified a yaml config to somewhat match your usecase as I've done something similar using a restarting script and a timeout before it's action is performed:

sensor:
  - platform: rotary_encoder
    id: my_rotary_encoder
    on_clockwise:
      - logger.log: "Turned Clockwise"
      - script.execute: stopped
    on_anticlockwise:
      - logger.log: "Turned Anticlockwise"
      - script.execute: stopped

script:
  - id: stopped
    mode: restart
    then:
      - delay: 500ms
      - logger.log: "Stopped turning"

That's kind of how I also do this.

For my Garage Door

By the way, how do you use a rotary encoder for a garage door?

[bkaufx]

I got the idea from this dude but haven't implemented it yet: https://paulwieland.github.io/ratgdo/

Look at his soldered wiring diagram and accompanying photo. I've been meaning to solder the rotary encoder of my garage door to a d1 mini.

For my Garage Door

By the way, how do you use a rotary encoder for a garage door?

By using a toothed Belt and getting the rotation from the shaft of the Motor. Combined with 2 Endstops i can see how wide the door ist opened. The counts reset at the Endstops.

I need the state opening or closing because the Garage door has only one input which toggles opening / closing the door.

At the Moment i got this:

output:
  - platform: gpio
    pin: 32
    id: output1

button:
  - platform: output
    name: "Garage Door"
    output: output1
    duration: 500ms

binary_sensor:
  - platform: gpio
    name: "Door open"
    id: door_open
    pin:
      number: 33
      inverted: true
      mode:
        input: true
        pullup: true
    on_press:
      - sensor.rotary_encoder.set_value:
          id: encoder
          value: 500
  - platform: gpio      
    name: "Door closed"
    id: door_closed
    pin: 
      number: 25
      inverted: true
      mode:
        input: true
        pullup: true
    on_press:
      - sensor.rotary_encoder.set_value:
          id: encoder
          value: 0

sensor:
  - platform: template
    name: "Direction Sensor"
    id: direction_sensor

  - platform: rotary_encoder
    name: "Öffnung"
    id: encoder
    min_value: 0
    max_value: 500
    on_clockwise:
      - sensor.template.publish:
          id: direction_sensor
          state: 1
    on_anticlockwise:
      - sensor.template.publish:
          id: direction_sensor
          state: -1
    pin_a:
      number: 12
      mode:
        input: true
        pullup: true
    pin_b: 
      number: 14
      mode:
        input: true 
        pullup: true 
    filters: 
    - lambda: |-
        auto first_mass = 100;
        auto first_value = 500;
        auto second_mass = 0;
        auto second_value = 5;

        auto r = map (x, first_value, second_value, first_mass, second_mass);
        if (r >0) return r;
        return 0;
    unit_of_measurement: "%"

BTW, the solution from Robomagnus works, thanks for that - i just didnt see it.

[nagyrobi]

I wonder how that could be properly combined with a cover component...

[Pippowicz]

But do you have to use the Cover component instead of using the single Entities? Perhaps im overthinking this and there is a better way, but i dont think here is the right place.

Thinking about dropping a post in the Forums.

[nagyrobi]

Post the link to the forums with your discussion on this

[Pippowicz]

Here is the Thread: https://community.home-assistant.io/t/esphome-custom-garage-door-integration/482125

[RoboMagus]

I guess this issue can be closed in favor of the forum thread then?

[Pippowicz]

Yeah, if you dont think about the on_stop trigger this can be closed.
