Sonoff S-MATE2 Smart Light Switch: No neutral wire required
This smart light switch is for the homeowner who wants to upgrade their existing switches without rewiring. It fits standard US 120 type electrical boxes and works with your rocker or toggle switches, making installation simple. You can control lights from your phone or set up automations in the eWeLink app, even without a neutral wire. The two-way control lets you turn lights on from the switch or remotely, and it pairs with eWeLink-Remote gateway devices like MINIR4 for reliable local control up to 50 meters away.
Think beyond basic on/off: use momentary switches to define scenes with single, double, or long presses, perfect for setting mood lighting or security routines. The battery lasts up to 5 years, so you won't worry about frequent changes. It supports up to 3 gang switches and 8 sub-devices per gateway, allowing you to expand your smart home setup easily. With certifications like FCC, it's built for safety and durability in indoor use.
