I think light switches are an absolutely fantastic UI. You can look at them to determine state, you an interact with them without unlocking a device and when they're placed well you can just "wave your hand" and lights come on.

However, when the light switches aren't well placed it is nice to add a layer of software abstraction between the switch and the light to be able to rearrange existing switches in your home without having to pull new wiring. So you can essentially just keep what you are already doing but make the existing, mature UI even more suited to your needs even if you're skeptical of all of the rest of it.
