The TREATLIFE 3-Way Smart Switch tackles a specific but common wiring scenario. It lets you control a single light from two different locations, like at the top and bottom of a staircase, and adds smart control to both switches. This is its core purpose, and it executes it cleanly without needing a dedicated hub.

Installation requires a neutral wire, which is standard in most homes built after the 1970s. The wiring is straightforward: connect the line, load, neutral, ground, and the two traveler wires. Once set up, you get reliable on/off control via the Treatlife app or voice assistants over a 2.4 GHz Wi-Fi connection. The physical switch has a satisfying, definitive click, maintaining the familiar feel of a traditional 3-way circuit.

It handles up to 1250W, so it can manage a bank of LED fixtures or several incandescent bulbs without issue. Just remember it’s for non-dimmable lights only. The included screwless wall plate gives a modern, flush finish. For a standard 3-way circuit upgrade, this switch delivers smart functionality without overcomplicating the basics.
