Here’s how it works: the Guardian Project turned a simple Raspberry Pi mini-computer into a smart hub running the open-source software called HomeAssistant software and acts as a so-called Tor hidden service, the same application of Tor that obscures the location of servers running dark web sites.
The result, says Guardian Project director Nathan Freitas, is a far stealthier and more secure way to connect your smart home to the Internet, while still keeping it safe from potential digital attacks.
“All we did was pull these pieces together to demonstrate a proof-of-concept for the role Tor can play in your home,” says Freitas, who’s also a fellow at Harvard’s Berkman Klein Center for Internet and Society. “It’s turning your Internet-of-things hub into a hidden service.”

Currently, I do not have any ports enabled on my router, that would allow me
to see my home devices (CAI controller, security DVR & etc), while I'm away from home..
My stuff can only be seen by using a direct home network connection. Either wifi or a LAN cable.
But, I would like to be able to see it while I'm away from home, and connected to a hotel or other public wifi system.
What do you experts think of the above solution?
