Well, there's two different types of smart switch: - The first type isn't actually connected to wall power, and is basically just a small remote that tells your lighting to turn on/off. - The second type is connected to the wall power, and works perfectly fine as a normal wall switch and controls the lights in the same way. Along with being a normal wall switch, it's a receiver and can receive commands from elsewhere (including the first type of smart switch) to trigger the normal wall switch functionality. The second type is an easy retrofit for existing homes with lots of lights, but doesn't play nice with smart bulbs that need to be always on for advanced functionality (like having automatic step-up/step-down lighting levels at sunrise/sunset). At the moment I feel like the best use of the first type are switches that fit neatly over normal hardwired wall switches (like the Lutron Aurora), or adding a spacer (see https://www.shapeways.com/product/35B9F36RD/philips-hue-dimmer-switch-spacer-plate-us-toggle https://www.shapeways.com/product/35B9F36RD/philips-hue-dimm... for one example) so that your smart switch can just be popped off to access the normal hardware.
