I didn’t replace the switches. They’re additional. The smart switch and the dumb switch both work. One great advantage is you can use a greater variety of bulbs and due to this fixture positioning is much more flexible. You can turn on 20 bulbs at once if you like. Make zones in your house. Turn on the whole house at once. Timers, programmed changes etc etc
