How do I make the binary sensor reset after x seconds?
Hi, when you say:
How is this done? In an automation, triggered by motion on a camera?
thanks!
Yes you can use automations, or trigger from the UI
So, this integration is not actively watching a camera feed for license plates but rather only does so when called by an automation? I think that this is good so that there is not an undue load on the cpu or the number of calls to the platerecognizer service. Sorry, but I do not see an example of an automation action that calls this service? Am I missing something?
thanks for the help!
Hereâs mine, it detects when my doorbell detects motion, and 1 second later it scans 1 still image from my other camera. I also use other automations and sensors to send notifications if someone i know is here.
alias: DoorBird Motion Plate
description: ''
trigger:
- platform: event
event_type: doorbird_doorbird_motion
condition: []
action:
- delay:
hours: 0
minutes: 0
seconds: 1
milliseconds: 0
- service: image_processing.scan
target:
entity_id: image_processing.platerecognizer_gate_camera_2
mode: single
Edit: And for the notifications, I first set up watched plates in configuration.yaml
watched_plates:
- EXAMPLEPLATE
- EXAMPLEPLATE
Then, I configured a Template Sensor for each one of my plates:
- platform: template
sensors:
plate_recognizer:
friendly_name: "Yukon"
value_template: "{{ state_attr('image_processing.platerecognizer_gate_camera_2', 'watched_plates').EXAMPLEPLATE }}"
unique_id: 'sensor.yukon_plate'
Now i have a sensor for each one of the license plates I want Plate Recognizer to watch for. 
Next, I used this to create an automation like this, that sends a notification to everyoneâs phone when the camera detects a familiar car.
alias: one of the plate sensors detected
description: ''
trigger:
- platform: state
entity_id: sensor.plate_recognizer_1
from: 'False'
to: 'True'
- platform: state
entity_id: sensor.plate_recognizer_2
from: 'False'
to: 'True'
condition: []
action:
- service: notify.notify_all
data:
message: '{{ trigger.to_state.name }} has been detected at the gate!'
title: License Plate Detection

It runs platerecognizer scan service when motion detected by door bird sensor

Hello,
i am trying to install this Haks.
but I always have these errors in starting home Assistat OS:
version = 1.4.1
2022-01-06 16:11:57 WARNING (MainThread) [homeassistant.components.image_processing] Setup of image_processing platform platerecognizer is taking over 10 seconds.

2022-01-06 16:12:47 ERROR (MainThread) [homeassistant.components.image_processing] Setup of platform platerecognizer is taking longer than 60 seconds. Startup will proceed without waiting any longer.
my config is:

watched_plates:

- kfab726
save_file_folder: /config/www/plates

suggestions?
Tnx Mauro

@robmarkcole If the license plate has a leading number the sensor template will not process. Dutch licence plates often lead with a number
Example this works:
- platform: template
sensors:
plate_recognizer:
friendly_name: "Audi"
value_template: '{{ state_attr("image_processing.platerecognizer_driveway", "watched_plates").abcde }}'
But this does not (different license plate):
- platform: template
sensors:
plate_recognizer:
friendly_name: "Audi"
value_template: '{{ state_attr("image_processing.platerecognizer_driveway", "watched_plates").4xjz58 }}'
The only difference is a number is leading the license plate.
This gives a template error in HASS:
Invalid config for [sensor.template]: invalid template (TemplateSyntaxError: expected token âend of print statementâ, got âxjz58â) for dictionary value @ data[âsensorsâ][âplate_recognizerâ][âvalue_templateâ]. Got â{{ state_attr(âimage_processing.platerecognizer_drivewayâ, âwatched_platesâ).4xjz58 }}â. (See ?, line ?).
This seems to be a different issue; After calling the service the state of this license plate = true (see also screenshot) so this all works fine. itâs the sensor template that does not render when there is a leading number
Hello. It doesnât work for Spanish license plates. If it does not start with a letter, the sensor gives an error and does not allow the automation to be saved.
Any solution?. Thank you.
Hi,
First of all really great job!
Iâm using it since today and works very nicely. Still I have a question: if I understand it right we canât directly send a picture (link of a picture) through this integration ?
Because for some cameras it would be nice if we could send a picture.
I have the Netatmo Outdoor Camera. This camera detects movement and even recognize when it is a vehicle. It then sends via webhook a sliced image with only the car that has moved. Is it possible to send this image directly to platereconizer?
Thanks
If you can display that image as a camera in home-assistant, then it can be processed with this integration. Iâm not sure how you would do it with webhook, perhaps using an automation, I am not too familiar with best practice using web hooks
HI,
I have just installed your project and it is very fine.
my question are: is it possible to show recognized plates in HA?
BR
All the recognised plates are in the attributes
Found that. Thanks.
I canât get the plate out of the entity. just a newbie.
Is there a way to show last 10 plates? I canât find it anywhere.
BR
Add this to a template sensor, it will list all the detected plates.
Probably a better way, but it will get you started
Youâll need to change the image_processing entity to whatever yours is called
- name: "Detected Plates Drive"
icon: mdi:numeric
state: >-
{% set vehicles = state_attr('image_processing.platerecognizer_drive_last_motion', 'vehicles') %}
{% if (states('image_processing.platerecognizer_drive_last_motion') !=0 and states('image_processing.platerecognizer_drive_last_motion') !='unavailable' and states('image_processing.platerecognizer_drive_last_motion') !='unknown') %}
{% for x in range((vehicles)|length) %}
{{ vehicles[x]['plate'] | upper }}
{% endfor %}
{% endif %}
If you have the sensor in the recorder, the history will show the plates over time
And have a look above thereâs a post on how to do it:
Is there an easy way to limit the amount of license plates it saves? I guess i could turn off the save options, but iâd still like a certain amount to be saved.
