Automation

[pilot1981]

Hi, I would use this project to create an automation on HA to open my house’s gate when my car arrived in front!

I would use:

• free account https://app.platerecognizer.com/products/snapshot-cloud/ (2500 plate/month are sufficient because no many cars come in front of my house)
• check new cars in image every seconds

it’s possibile? You see any limitation?

I could have some issue with automation in this type of case?

[robmarkcole]

Should be fine, unless there are many false positives. You could just trigger on motion detection

[pilot1981]

I don't have webcam with motion detection: what you suggest to do? I can use some other software to process it and create a virtual motion detection? what's your suggestion?

[robmarkcole]

Hmm you could do some kind of routine based on geofencing. Simplest would be to install an actuall sensor on the gate, e.g. PIR

I can't use found event of image processing of HA?

I create an automation that when event plate found is triggered...it send plate image to PlateRecognizer cloud...it can works?

Hi, I have proble creating 2 template sensors: 1 for each plate.

this is my configuration.yaml: ´´´ sensor:

• platform: template sensors: plate_recognizer: friendly_name: "elxxxkf" value_template: "{{ state_attr('image_processing.platerecognizer_telecamera_retro3_2', 'watched_plates').elxxxkf }}"
• platform: template sensors: plate_recognizer: friendly_name: "gfxxxky" value_template: "{{ state_attr('image_processing.platerecognizer_telecamera_retro3_2', 'watched_plates').gfxxxky }}" ´´´

but I only obtain elxxxkf sensor plate...no any gfxxxky sensor plate....why? you have some suggestion? I already tried the suggested config in your wiki...no luck!

[pilot1981]

@robmarkcole , please update sensor template according to last version of HA; here my examples:

´´´ template:

• sensor:
  • name: "targa_ELxxxKF" unique_id: plate_recognizer_elxxxkf state: "{{ state_attr('image_processing.platerecognizer_telecamera_cancello_profile_000', 'watched_plates').elxxxkf }}"
  • name: "targa_GFxxxKY" unique_id: plate_recognizer_gfxxxky state: "{{ state_attr('image_processing.platerecognizer_telecamera_cancello_profile_000', 'watched_plates').gfxxxky }}" ´´´

according to https://www.home-assistant.io/integrations/image_processing/

why I don't found in my installation entity openlapr.xxxx?

it is possibile use built image processing feature of HA to send image to PlateRecognizer cloud only when a license plate is recognized?

[pilot1981]

Hi @robmarkcole, I'm deployment an installation at home using your project, but I don't have license plate stay in front for camera foir many seconds soI'm not able to take and send the right image of license plate to platerecognizer cloud.

what do you suggest for it?

Car is under 20 km/h...when ONVIF camera send motion detection alarm, can I take and send 10 images to plate regcognizer cloud? do you suggest to use a custom automation for this purpose? do you have other suggestions?

regards

[robmarkcole]

So the problem is, since the car is moving, when motion triggers the e camera the car is already out of frame? In this case you need to process continually to detect the car with the camera, the send the best image to this integration. Checkout Frigate forums for an approach

[pilot1981]

for testing purpose, how I can uploda specific images to plate recognizer cloud?

[robmarkcole]

You can use the https://www.home-assistant.io/integrations/local_file/

[pilot1981]

Hi, I'm trying to send to platerecognizer cloud multiple images to get the right image with the best license plate image, so I'm tryning to send 5 images in less than5 seconds, but I see only 2 images on plate recognizer cloud: there is some limitation in plate recognizer service?

I let also an example of HA automation I'm using:
