There are battery-free ones now. But normally battery lasts at least 2 years. IF battery dies you still have option to go thru pain and horrid of using siri or smartphone to toggle your lights... You can install wired smart switches, but that would be incredibly stupid on a new build. The whole point of it isn't walking to it (that's how I use it 99% of time). It's automation of switching all lights at once when going to bed, or all lights switching off when you leave house, or light comes up when you get home after sunset.
