Remote Breakers or Relays

So i just stumbled upon a youtube video that details how he's using relays to control his breakers.

From google searching it looks like you can purchase remote breakers, but I'd need some type of controller that would speak with it (i think).

Has anyone done anything like this before?

There was a thread about remote breakers a month or so ago.

Thanks for the info.

Thinking more about this, this wouldn't exactly be an easy project to even consider. You'd have to re-wire your whole house. I assume something like this would be better in a new house build or better yet geared towards a commerical application.

It would be expensive for the Leviton panel I'm sure and I would be uncomfortable using WiFi to connect to my electrical panel. Other than power monitoring, I don't really see much real benefit.
