Another late answer, but this is one where things have changed since you first wrote.
See the following FAQ for how to combine switches with smart bulbs. The most significant change in just the last few months is The release of a couple of devices that are smart switch covers. They fit over your existing light switches. So you leave the existing switch there, powered on, so that the smart bulb is always powered on. But the switch cover has its own buttons that you can press for on and off. That gives you an intuitive wall switch, but your bulbs never lose power. And no rewiring required. There are also multiple other options discussed in the thread.
