A:AnswerHue requires a hub. Smartthings requires a hub as well. Without getting into the hacking world, I don't believe you can hook this plug directly to the Hue hub. If you have both hubs, you can control and coordinate Hue through Smartthings. I have both systems and have chosen to run them independently with no linkage. I like the fact that the Smartthings Hub has a battery back-up that keeps everything going for a few hours if the power is out.
A:AnswerCheck the amps on your water heater but it is not likely that the outlet can carry that much current. I did something similar in my house in Costa Rica but I used the smart outlet to control a relay which in turn controls the water heater.
