within your electrical distribution panel. Connect the input live conductor to the L terminal, connect neutral wire to the N terminal if available (neutral is optional), and connect the two independent load circuits to the OUT1 and OUT2 terminals respectively. Ensure all connections follow local electrical codes and are performed by qualified electricians. Power on the device and verify the LED indicator illuminates, confirming proper power supply connection and microprocessor initialization.\u003c\/p\u003e\n\n\u003cp\u003eDownload the eWeLink application on your iOS device and create an account if you do not have one. Press and hold the manual button on the device for 3-5 seconds until the WiFi LED blinks rapidly, indicating pairing mode activation. In the eWeLink app, select Add Device, choose Sonoff Dual R3, and enter your WiFi network credentials. The device will connect to your 2.4GHz WiFi network within 30 seconds. Once connected, you can control both channels independently through the app, create automation schedules, set up Siri voice commands through the Home app integration, and monitor real-time switching status. For voice control, add the device to Apple Home app, assign it to a room, and use Siri commands such as \"Turn on Channel 1\" or \"Turn off the living room lights\" for hands-free operation.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan the Sonoff Dual R3 work without a neutral wire connection?\u003c\/summary\u003e\n\u003cp\u003eYes, the Sonoff Dual R3 is specifically designed with neutral wire optional capability. However, for optimal performance and to ensure proper relay operation across all load types, connecting the neutral wire is recommended. Without neutral connection, the device may experience reduced compatibility with certain load types or voltage instability. Always consult with a qualified electrician to determine if neutral wire is available in your installation location.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum load capacity for each channel?\u003c\/summary\u003e\n\u003cp\u003eEach channel of the Sonoff Dual R3 can handle a maximum of 10 amperes at 250V AC. The combined maximum capacity of both channels is 20 amperes. If you need to control loads exceeding 10A per channel, you should use the relay output to trigger a larger contactor or relay rated for higher currents. Always verify your load specifications before installation to prevent relay damage and ensure safe operation.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eDoes the Sonoff Dual R3 require a separate smart home hub?\u003c\/summary\u003e\n\u003cp\u003eNo, the Sonoff Dual R3 does not require a separate hub or bridge. It connects directly to your 2.4GHz WiFi network and communicates with the eWeLink cloud platform. However, for advanced features such as local network control without internet connectivity, you may optionally set up a Sonoff Bridge or use the eWeLink local control feature if your router supports it. Siri voice control integration works through the eWeLink app without requiring additional hardware.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan I control the Sonoff Dual R3 when away from home?\u003c\/summary\u003e\n\u003cp\u003eYes, the Sonoff Dual R3 provides full remote access through the eWeLink mobile application from anywhere globally with internet connectivity. Your device is registered to your eWeLink account in the cloud, allowing you to control both channels, view status, and receive notifications regardless of your physical location. All communication is encrypted using HTTPS protocol for security.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow do I set up Siri voice control?\u003c\/summary\u003e\n\u003cp\u003eTo enable Siri voice control, you must add the Sonoff Dual R3 to Apple Home app. In the eWeLink app, go to device settings and select \"Add to Home\". Scan the HomeKit code from the device packaging or settings screen using Apple Home app. Once added, you can create custom names for each channel and use Siri commands like \"Hey Siri, turn on Channel 1\" or assign them to specific rooms for context-aware voice control.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat happens if my WiFi connection drops?\u003c\/summary\u003e\n\u003cp\u003eIf your WiFi connection is interrupted, the Sonoff Dual R3 retains its last known state and will not automatically switch channels. However, the manual button on the device allows you to control both channels locally without WiFi connectivity. Once WiFi is restored, the device automatically reconnects to your network and synchronizes with the eWeLink cloud platform. You can then resume remote control through the mobile app.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
