This is a configurable keypad. It can not directly connect to a load. It is used to wirelessly control other lighting devices and smart home functionality. So as a 'slave' in a 3 way or 4 way, it is a great upgrade from the KA since it can do way more than a KA. Be aware that it requires power, and many slave locations do not have a live power, although often the electrician can use the traveler wire to bring power to the box from the main load location.
