I am not sure other ways, but it is possible to write a driver that monitors a webpage and parses the data on it. It is EASIEST if the data is represented using XML or JSON but depending on how far you are willing to go you can make a driver parse pretty much anything.
For example, my Neptune Systems Apex driver reads the json output that controller outputs (at a cgi-bin/status.json page) and brings the data into my Hubitat.
