Indeed it would be nice to be able to set a zoom value. I have a Kindle Paperwhite and possibly because of its higher definition, the items in the page appear really small...

Rather than uploading the generated index.html file onto my Kindle, I placed it into the www folder of my hassio config folder to access it pointing the Kindle browser at address http(s)://HASSIO_ADDR:8123/local/index.html. I find this more convenient to adjust sensors, switches, etc on the fly. Maybe this strategy could be added to the explanation README.md file.
