If you have smart light bulbs from a smorgasbord of brands, you can control them all using sensors paired to a smart-home hub or speaker. You can then set up Automations that turn lights on when you open a door and off when you close it (ideal for closets, pantries, and laundry rooms) or turn them on when there is motion and off when no one is around (great for busy rooms such as kitchens and living rooms). You can add other elements into the mix, too, such as the brightness level, any color adjustment, and the time of day.
