SSOCR no output / not installed?

Configuration
1

Hi,

since the approach of using tesseract in node-red to read the temperature of my heatpump does not seem to work (unable to import some trained data set built for 7 segment characters, see Node-Red Tesseract OCR to read heatpump temperature - #6 by smi) I tried using SSOCR.

This is my current config:

camera:
  - platform: local_file
    file_path: /config/www/images/heatpump4.jpg
    name: heatpump_cam
  - platform: local_file
    file_path: /srv/homeassistant/img_2_processed.jpg
#    file_path: /local/images/img_2_processed.jpg
    name: ssocr_processed

image_processing:
  - platform: seven_segments
    source:
      - entity_id: camera.heatpump_cam
    x_position: 0
    y_position: 0
    height: 580
    width: 685
    threshold: 0
    digits: 2
    extra_arguments: '-Dimg_2_processed.jpg'

Unfortunately, in the log, I get:

Logger: homeassistant.components.seven_segments.image_processing
Source: components/seven_segments/image_processing.py:135
Integration: seven_segments (documentation, issues)
First occurred: 18:44:49 (31 occurrences)
Last logged: 18:50:10

Unable to detect value: found only 0 of 2 digits

The input image looks like this:

Also, I can’t use ssocr via terminal (running hass.io) as it says “service unknown” while the integrations appears under system info in the frontend and I can’t find the processed image (if there is one) from SSOCR.

Any idea on how to get Seven Segments OCR running? Are there any additional steps required to setup SSOCR on hass.io? The documentation only says so for core installs.

Thanks!

Ok solved it.

The documentation is wrong here.

It requires ALL of the following to be in the config:
x_position, y_position, width, height AND threshold

Does anyone know how to install ssocr on HomeAssistant OS?
It says it’s pre-requisite for running the Seven Segments OCR integration.
I’m running home assistant on a Pi 4.!
The instructions in the integration page are not exactly enlightening:

Can someone please help? Thank you!
