The instructions were a little confusing at first, but it all works well in my CR-10S4. The 8.3 file format is a bit annoying though. I would really like them to upgrade the firmware to support long file names and try and get the time of day from the router somewhere for the file system.
Works little slow, but works, maybe need a firmware update and some improvements but is cool so I hope they can upgrade this dispositive with esp32 or I don't know.
