It doesn't seem to have got to their database yet, though I'm not sure what device category they'd put it under (I searched under Digital Set Top Box, Beyonwiz, wiztv). It suggested I try the Beyonwiz T4 device instead.
I did an image search on the remote control image that Jai posted, and found quite a few matches, but for Android TV boxes that didn't even vaguely resemble the WizTV dongle. I couldn't find the manufacturers of any of them in the Harmony database, anyway, so I never got as far as being able to test whether they sent the same codes, or to have them learn the codes from the WizTV remote.
