Hi

I’m using outdoor nest cameras that are 24/7 powered. I have setup the integration correctly but when start the image proccessing the png saved doesn’t have a picture. The file is there in the confit folder but there is no picture, it’s just white

I don’t have a car to test with this evening, does a car need to be in the frame of the camera for the image processing event to generate a picture?

Any idea's what is causing this?

Running release 1.1.0 of Plate and HA 2021.5.2

I can get plate recognizer to work with my home assistant however I am having issue when adding watched plates sensor

Below is my sensor code

sensor:

• platform: template sensors: plate_recognizer: friendly_name: "abc12d" value_template: "{{ state_attr('image_processing.platerecognizer_1', 'watched_plates').abc12d }}"

Home Assistant having this warning in the log

When I scan plate-recognizer, it can detect my license plate but the sensor does not change state. My home assistant version is core-2021.9.0b6.

Since updating to 2022.4.b0 All attributes missing from image_processing entity. State works OK and is showing the number of plates.

Set logging to debug and only shows this:

2022-03-31 17:38:12 DEBUG (SyncWorker_17) [custom_components.platerecognizer.image_processing] Config: {"detection_rule": "strict", "region": "False"}

Looking on Platerecognizer's website, it says it returns coordinates of the detected plate box, is this possible to add ?

The centre of the box would suffice, I would like to check where each plate is detected (drive or road)

results/box | Bounding box for the license plate. Coordinates in pixel of the top left and bottom right corners of the plate. -- | --

Hey Rob

Firstly, thank you so much for this. We live on a large rural property in Australia and are using this to work out who is at our gate and automatically open the gate if we like them :)

I wondered if you had considered allowing the intergration to connect to a on-premise instance of plate recogniser (running in a docker container).

https://app.platerecognizer.com/sdk/

I wish I knew how to code, in which case I would raise a PR and not an issue.

Please keep up the great work.

P.S. I have been working with Plate Recogniser to get a more affordable plan for plan for us all. The new plan pricing will work for Cloud and SDK licenses.

It would be great to be able to use an url or a file for source instead of camera.

Use case I'm using Frigate as NVR- software and when using the official HA-component for Frigate it creates all cameras in HA with a max height of 277px. I've found that that is a little bit to small for my setup when running plates. It would be great to be able to set an url directly to my Frigate instance where I can access a full resolution image of the camera feed.

Love the integration, but in my opinion this would be a better default location, because then you can create local file cameras, and otherwise you can't do things like send the latest image in a notification via automation.

Parallels https://github.com/robmarkcole/HASS-Sighthound/issues/22

Add a watched_plate arg that is a list of plates to watch for, allowing fuzzy matching. I.e. a matched plate will be detected when there is a good match of characters using regex. For each plate an attribute is exposed which is a binary sensor indicating if the plate was in the last scanned imaged or not. Add a watched_plate event as well?

My country plate start with number like

29a12345

if I put this in template

plate_recognizer: friendly_name: "29a12345" value_template: "{{ state_attr('image_processing.platerecognizer_frontgate', 'watched_plates').29a12345}}"

will error

Invalid config for [sensor.template]: invalid template (TemplateSyntaxError: expected name or number) for dictionary value @ data['sensors']['plate_recognizer']['value_template']. Got "{{ state_attr('image_processing.platerecognizer_frontgate', 'watched_plates').'29a12345' }}". (See ?, line ?).

Also, can i put image_processing in a file rather then configuration.yaml ?

Finally, is the sensor configuration new style or old style?

Thanks for your help!

Any idea what would cause this?

This error originated from a custom integration.

Hi, Thanks for the effort.

I am trying to use this integration with the region "no", and i get the following error message in the system log: platerecognizer api response: {'regions': ['Region "False" does not exist. List of regions: http://docs.platerecognizer.com/#countries']}

My yaml contains the following:

regions: - no

Workaround is to use: regions: - dk

I want to make an sensor where I can se the last plate found NOT known.

here is what I have been trying.

in developer tools:

{{ state_attr('image_processing.platerecognizer_garage_2' , 'vehicles') }}

output

[{'plate': 'nkeXXXX', 'confidence': 0.683, 'region_code': 'pl', 'vehicle_type': 'Big Truck', 'box_y_centre': 116.0, 'box_x_centre': 1563.0}]

so I want to show attribute 'plate'

{{ state_attr('image_processing.platerecognizer_garage_2' , 'vehicles').plate }}

output

none

expected output

nkeXXXX

is there something I am missing ?

Can the filenames generated be customized? I just need the format to be shorter to display neatly in my gallery browser card but the generated filename is something like platerecognizer_driveway_cam_jpg_2022-07-22_10-04-48 which is really long and messes us how things are displayed with text for thumbnails overlaying on top of each other etc.
