The video shows a shut down and reboot button on the app?
I'm not sure what your question is - Windows already lets you reboot and shutdown, there's no magic to that. It's literally just their app sending the command - it's not something special about their PSU. If you could remote power ON the device, then that would be much more interesting, but also much more difficult.
In the PDU model, you could configure the system to auto-start on power loss, and you can toggle the power on and off to the outlet (assuming it's a managed PDU). This is radically different than what they're offering - it's literally just an app to allow you to remote reboot or shutdown your machine. You could do that using TeamViewer or any number of other things...
Now they've also added monitoring of the PSU state, like voltage levels, fan speed, temps - and those are interesting, but at least in my experience I've never had a fan fail, and if I'm pushing a PSU, I'm not going to use some consumer grade one... So these are of marginal value (at least to my mind).
