## Summary description

Sonoff Smart 2‑Channel Wi‑Fi Switch DUALR3‑LITE is a two‑gang wireless relay module for remote switching and automation of electrical loads. It connects to a Wi‑Fi network to control two independent circuits via smartphone app or voice assistants, supports local and remote control, scheduling and scene automation, and is suitable for lighting and small appliance control.

## Long description

Sonoff Smart 2-Channel Wi‑Fi Switch DUALR3‑LITE is a compact two‑gang wireless relay module designed for remote switching and automation of household electrical loads. The device connects to a 2.4 GHz Wi‑Fi network and enables control of two independent circuits via the eWeLink mobile app or compatible smart home platforms. It supports local and remote control, scheduling, scene automation and voice assistants, and can operate in switching and motor modes for devices such as tubular motors used with roller shutters, blinds and awnings. The module does not measure power consumption and is sized for installation inside sockets, behind switches or on DIN rails.
Advantages
The dual-channel design provides independent control of two circuits while remaining compact enough for concealed installation. Built‑in compatibility with eWeLink, Amazon Alexa and Google Assistant enables app control, voice commands and integration with broader smart home scenarios. Scheduling, timers, device grouping and scene creation allow automated routines and synchronized control. The relay supports motor mode suitable for 100–240 V AC tubular motors and offers two‑way switching for multi‑location light control. Safety features include PC V0 flame‑retardant housing and common wireless security standards.
Suitable for
 Remote control of lighting circuits in multi‑location (two‑way) setups
 Control and automation of tubular motors for roller shutters, blinds and awnings
 Integration into schedules and scenes for daily automation
 Voice‑controlled switching through Alexa or Google Assistant

How to use
Install the DUALR3‑LITE module according to local electrical regulations: power off the circuit, connect line and neutral and wire the two output channels to the loads or motor terminals as required. After restoring power, install the eWeLink app on your Android or iOS device, create or sign in to an account and follow the in‑app instructions to add the device via the 2.4 GHz Wi‑Fi network. Configure channel names, set motor or switch modes if controlling tubular motors, and create timers or scenes as needed. For two‑way light control, wire external wall switches to the appropriate inputs and verify switching behavior before finalizing installation.
Usage recommendations
Use the module with loads and motors within the specified voltage and current ratings. Do not exceed per‑channel or total current limits. Ensure a stable 2.4 GHz Wi‑Fi signal at the installation point for reliable remote control. For motorized blinds and shutters, set the motor mode and adjust run times in the app to avoid overrun; consult motor manufacturer instructions for compatibility. Install the device in locations protected from direct moisture and within the recommended temperature and humidity ranges. If unsure about wiring, use a qualified electrician for installation.
