The Sonoff DualR3 Lite is a smart Wi-Fi switch that allows you to control two separate devices (or circuits) independently through your smartphone, voice assistant, or automation system. It's designed to be installed behind a traditional wall switch or socket, allowing for a hidden installation that makes your devices smart without altering your home's appearance.
Key Features:
✅ Two Channels:
- Control two devices independently, such as two lights or two appliances.
✅ App Control:
- Use the eWeLink app (available for iOS and Android) to turn devices on and off from anywhere.
✅ Voice Control:
- Works with Amazon Alexa, Google Assistant, SmartThings, etc.
✅ Schedules & Timers:
- Set automatic schedules, countdown timers, and even loop timers for each channel.
✅ Scenes & Automation:
- Link with other smart devices to create powerful automations (example: when motion is detected, turn on lights controlled by DualR3 Lite).
✅ Hidden Installation:
- Designed to be installed behind standard wall switches or power outlets.
✅ Power Monitoring (⚡️Not Available on Lite Version):
- Note: The "Lite" version does NOT support power consumption monitoring.
- If you want energy monitoring, you need the regular Sonoff DualR3 (non-Lite).
✅ Interlock Mode:
- Allows only one channel to be ON at a time — great for applications like motor control (but this is more common in the regular DualR3).
Important Differences from DualR3 (standard version):
- No Power Monitoring in the Lite version.
- Same control features (on/off, timers, schedules).
- Lower price than the standard DualR3.
Typical Uses for DualR3 Lite:
- Make a double light switch smart.
- Control two sections of LED strips separately.
- Automate turning on and off two fans, heaters, pumps, etc.
