Sonoff Dual R3 Lite Smart Switch Wi-Fi

This compact module installs behind standard wall switches and connects to 2.4GHz Wi-Fi, allowing users to control devices remotely or via voice. It supports switch mode for controlling two separate appliances and motor mode for managing motors with travel limits (e.g., blinds or shades).

The Dual R3 Lite is ideal for smart lighting, automated window coverings, and dual-appliance control. It supports scene automation, timers, and schedules, and allows two-way control with physical switches. The device is DIN rail compatible, LoA and ICASA approved, and requires a neutral wire for installation.

Unlike the standard Dual R3, the Lite version does not include energy monitoring, making it more affordable while still offering robust automation capabilities.
