## Long description

Sonoff T3US1C is a 1-gang Wi‑Fi smart wall switch in black designed for US wiring and form factor. It replaces a standard single-pole wall switch and enables remote control of a single lighting circuit via the eWeLink mobile app, while still allowing local manual switching. The device supports scheduling and basic automation to integrate a conventional light fixture into a smart home setup without changing existing wiring layout when compatible with single-pole installations.
Advantages
The Sonoff T3US1C offers remote on/off control and timed scheduling through a mobile app, allowing users to manage lighting from anywhere. Its inset design and US-compatible form factor make it a direct replacement for many standard wall switches. The switch preserves local manual operation so users can continue to use the physical button, and it integrates with common smart home workflows for basic automation tasks.
Suitable for
Replacing a single-pole wall switch in US-style electrical boxes
Remote control of a single lighting circuit via smartphone
Scheduling lights for energy savings and convenience
Integrating conventional lights into basic smart home automations

How to use
Turn off power at the circuit breaker before starting installation. Replace the existing single-pole wall switch by connecting the live (hot) and load wires to the corresponding terminals on the Sonoff T3US1C, and attach the neutral or ground as required by local wiring and the device's installation instructions. After wiring and securing the switch in the wall box, restore power and follow the eWeLink app pairing procedure to add the switch to your Wi‑Fi network. Once paired, use the mobile app to set schedules, control the switch remotely and set up basic automations; the physical button on the switch continues to operate locally.
Usage recommendations
For safe and reliable operation, verify compatibility with your existing wiring (single-pole circuits) and the wall box depth before installation. If unsure about wiring or local electrical codes, consult a qualified electrician. Use the latest version of the companion app for firmware updates and to access scheduling and automation features.
