The Pentair 011075 is the basic 3hp model. I bought one last week, and will install it in a week or two. You can control it via wifi / home app. I guess by a video or two, you can also do some very basic controls on the unit itself.
The Pentair 011076 is exactly the same, but it includes the relay board. The relay board allows for two items to be attached (and controlled) by wifi. As previously mentioned, the controlled is just power. So, lights on one, and a booster pump on the other, maybe.
Youtube search for pentair intelliflo relay board programming and you'll see a few good videos.
For me, since I bought the pump already, and am also buying an SWCG, I'm going to buy the relay board separately. It'll be worth it.
