Passing attribute and call service - Fingerprint R503

[groot29 (Gianni)]

Hi everyone
I configured my GROW R503 sensor with esphome:

uart:
  rx_pin: GPIO13
  tx_pin: GPIO14
  baud_rate: 57600

fingerprint_grow:
  sensing_pin: GPIO12
  on_finger_scan_matched:
    - text_sensor.template.publish:
        id: fingerprint_state
        state: "Impronta autorizzata"
    - delay: 3000ms
    - lambda: |-
        if (finger_id == 0) {
          id(fingerprint_username).publish_state("Fred");
        } else if (finger_id == 1) {
          id(fingerprint_username).publish_state("Gianni");
        } else {
          id(fingerprint_username).publish_state("Unknown");
        };
    - text_sensor.template.publish:
        id: fingerprint_state
        state: "Attesa"
    - fingerprint_grow.aura_led_control:

    - fingerprint_grow.aura_led_control:
        state: FLASHING
        speed: 25
        color: RED
        count: 2

    - text_sensor.template.publish:

        count: 4

api:
  services:
  - service: enroll
    variables:
      finger_id: int
      num_scans: int
    then:
      - fingerprint_grow.enroll:
          finger_id: !lambda 'return finger_id;'
          num_scans: !lambda 'return num_scans;'

# Optional template text sensor for visual feedback

# Optional sensors

      name: "Stato impronta"
    capacity:
      name: "Capacità impronta"
    security_level:
      name: "Livello di sicurezza"

i want pass to service call esphome.esphome_fingerprint_ingresso_enroll, finger_id the value of input_number_id_impronta for adding a new fingerprint.

I write the value

this is lovelace card

show_name: true
show_icon: true
type: button
tap_action:
  action: call-service
  service: esphome.esphome_fingerprint_ingresso_enroll
  target: {}
  data:
    finger_id: '{{ states(''input_number.id_impronta'') }}'
    num_scans: 2
name: Registra Impronta
icon: mdi:fingerprint
icon_height: 50px

help please…
Thank you

Garage Fingerprint Sensor

Today I wanted to share how I made a fingerprint sensor to control my garage. [IMG_2786] It’s what got me in Home Assistant for the first time. I wanted to be able to control my garage from my phone. That’s some time ago, but now I can also control it with a fingerprint sensor I won’t cover how I control the garage itself in this topic, but mainly how to control the fingerprint sensor and how to build it into a wooden object. What you need: GROW R503 fingerprint sensor (Aliexpress) …

There is a simple solution in the code to enroll another fingerprint mentioned by nickrout. Just add this to the services in the api section:

  - service: enroll_next # Idea by Ralf Klüber (thanks!)
    variables:
      num_scans: int
      count_plus: int
    then:
      - fingerprint_grow.enroll:
          finger_id: !lambda 'return count_plus + id(fingerprint_count).state;'
          num_scans: !lambda 'return num_scans;'

I just made some progress on adding your original question, but will post this seperately, once I am done.

Your approach seems fine,.e.g. the same i am summarizing below.

But i think you have to format the input as integer.
finger_id: "{{states('input_number.fingerprint_modification_id') | int}}"
At least thats the only notable difference i see. For me it is working.

The problem can be solved as follows.

1. Create a number Helper in devices, helper. Call
   

   
   
   This you add to the frontend as part of a dashboard card to enter the number.

2. Create a script for every button you want

alias: Fingerprint Learning 30s
sequence:
  - action: esphome.fingergarage_enroll
    metadata: {}
    data:
      finger_id: "{{states('input_number.fingerprint_modification_id') | int}}"
      num_scans: 2
  - delay:
      hours: 0
      minutes: 1
      seconds: 0
      milliseconds: 0
  - action: esphome.fingergarage_cancel_enroll
    metadata: {}
    data: {}
description: ""
icon: mdi:fingerprint

Certainly you skip the timer and the cancellation if not wanted.

3. Now add the button to your card as well.
