Sure, I can help you with that! To have smart color changing LED recessed lights that can also be controlled with a wall switch, you will need a few components:

1. Smart LED lights: You can choose any brand of smart color changing LED recessed lights that are compatible with your home automation system. Some popular brands include Philips Hue, LIFX, and Sylvania Smart+.
2. Smart hub: A smart hub is a device that connects your smart lights to your home automation system. You can choose a hub from the same brand as your smart lights, or use a universal hub like the Samsung SmartThings hub or the Amazon Echo Plus.
3. Wall switch: You will need a wall switch that is compatible with your smart hub. There are several options, including smart switches that can be controlled with an app or voice command, or traditional switches that can be connected to a smart home system through a smart hub.
4. Wiring: You will need to wire the smart switch to the power source and the smart hub. If you're not comfortable with electrical wiring, it's best to hire a licensed electrician to do the job for you.

Once you have all the components, you can install the smart lights in the desired locations and connect them to your smart hub. Then, install the wall switch and connect it to your smart hub as well. You should be able to control the lights with the wall switch, as well as through your home automation system or with voice commands if you have a compatible smart speaker. You can also use the app to change the color and brightness of the lights.
