I have a control4 dealer testing a few lights in their lab (Halo/Hue), but I think the answer is not going to be great. Lutron does make a dial dimmer switch which basically locks a switch in the on position which could probably work, but I hate the look of it. Generally speaking, because the lights need to be powered on all the time to enable the smart features, you can't really use them with in-wall dimmer switches which, at least as I understand it, don't give enough power to keep the signal strong and allow for smart features.
There is a solution that works with control4, but it is much more expensive for the recessed cans. Ketra is one solution and the other is DMF lighting but the tunable range isn't that great. Or, you could go with a full low voltage lighting solution if you haven't wired anything yet, and then you can get whatever you want.
Long story short...for more reasonably priced recessed cans that are "smart", I don't think tunable is really going to work with Control4 or any dimmer switch for that matter. The other alternative is that you just remember to never turn off the light switch (or wire it always hot) and have another smart switch somewhere that talks to the smart features. Control4 integrates with Hue so that could work, I just think it is unnatural and not realistic to think people in the house are not going to accidentally hit a light switch.
