The Control 4 and Control 2 has Two drive ports which can drive pumps, relays etc. directly. Means they do not need to be on the WIFI strips, They just have to have the connector for it. So if you use their ATO or one of their pumps made to run off a drive port that is one thing that does not need a Wi-Fi strip.
Heater, return pump, skimmer, Ap700 have to go Wifi plug strip. Reactor could just go to a normal power, does it really need to be on the controller? What kind of reactor? If you want it on it looks like to me you will need two WIFI Strips..
Does the AP700 have 0-10v? If so they may eventually have a cable for 0-10v which means you could use the Control to control the lights and then power them from normal power. I am guessing that is future though.
