Perfect for managing lights in a multi-story home, the TREATLIFE 3-Way Smart Dimmer Switch replaces your standard 3-way setup. Use it at the top and bottom of your stairs or in a large living room with two entrances. Unlike basic switches, this dimmer remembers your preferred brightness, so your stairwell lights come on at a soft 20% every evening.
Installing this switch requires a neutral wire and a 2.4GHz Wi-Fi network. The included two master switches work independently for different circuits, so you can automate your hallway and bedroom separately. Voice control is reliable: tell Alexa to dim the lights to 50% and it responds instantly without delays. The Smart Life app lets you set schedules to turn on lights before you arrive home, adding security.
One practical detail: the switch's dimming range from 1% to 100% avoids the sudden brightness jumps found in other models. The built-in brightness memory ensures your last setting stays, so you don't have to readjust every time.
