Wanted to add that the manufacturer released their drivers which now have the reset capability.
In all honesty, I actually tried uploading the Zooz firmware onto the device. It accepted the fw but then for a while it wasn't reporting its actual state (off when on, on when off). So I decided to revert to the mfg firmware and got it from their page.
The issue for me was that having a C4 I didn't have a way to upload from the hub as the only way was to provide an http url to the *.gbl file. So what I did was self host the file on one of my computers and got the device firmware uploader to use that url.
Here is the driver and firmware download page: https://minoston.com/download-indoor-smart-plug-2/?swcfpc=1
