OpenALPR Local missing binary

Hello all!

I’m trying to get a camera to read my license plate and open / close the garage door. I see that OpenALPR Local is available as a component here - I set it up and I end up with a stack trace :frowning:

2020-09-14 12:51:26 ERROR (MainThread) [homeassistant.helpers.entity] Update for image_processing.openalpr_driveway fails

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'alpr'

As you can see - I don’t think that alpr has been installed on HA. What is the easiest way for me to solve this? I can enable SSH on port 22222 and install it on the base O/S I assume?

However, if I do succeed in doing that it will be removed whenever the next Home Assistant OS update comes along and I install it. Is that correct?

Is there some way I could do this so that I could add it to the current image and create a PR and we could all get the new functionality?

Thanks all!
