I wanted to start doing license plate recognition today and noticed there wasnt a Hassio addon for it and therefore wrote one (using a docker image thats already out there). It provides an port for you to query via http.
Its really rough and ready and i’ll define it properly over the next week or so.
Right now it seems to take an age and forever to build, however once done its really nice to use with Nodered HTTP Request ( http://:5000/plate )
