This is one thing that worries me as well. Fortunately, none of my smart home stuff is cloud connected. Most smart home problems that tend to be solved by using a cloud service could be solved just as well by using a VPN. I do this with my Hue and my Wifi cameras, both with great success. The challenge with a VPN is setting it up. Router manufacturers generally either offer OpenVPN, which requires a 3rd party app, or PPTP, which is horribly insecure. A router that could generate a secure IPSec configuration and push out a profile for the smartphones would make it a lot more usable. Even then, it's still probably going to be more work than using a cloud service. Maybe IPv6 will solve the problem as all of these things can have publically routable addresses. What could possibly go wrong?
