Frequently Asked Questions - DUALR2 Sonoff

How to install the Sonoff DUALR2 smart switch?

Installation must be carried out by a qualified professional to avoid the risk of electrocution. Cut off power before starting. Ensure that the neutral wire and live wire are correctly installed according to the provided wiring diagrams.

How to connect the device to the eWeLink app?

Download the eWeLink app from the App Store or Google Play. After turning on the device, it enters quick pairing mode (Touch). Press '+' in the app and select 'Quick Pairing', then follow the prompts.

What does the Wi-Fi indicator blinking mean?

The blue Wi-Fi indicator shows different states: long blink then two short = quick pairing mode; steady on = connection successful; fast blinking = compatible pairing mode; one short blink = router not found; two short blinks = connected to router but not to Wi-Fi; three short blinks = update.

Why is my device staying offline?

Check the following causes: incorrect Wi-Fi password, too far from router, using 5 GHz Wi-Fi (not supported), MAC filtering enabled. Wait 1-2 minutes after adding. If the problem persists, try with a mobile hotspot.

What to do if quick pairing doesn't work?

Use 'Compatible Pairing Mode'. Press and hold the configuration button for 5 seconds until the Wi-Fi indicator blinks rapidly. In the app, select 'Compatible Pairing Mode', connect to Wi-Fi SSID ITEAD-****** with password 12345678, then return to the app and follow the instructions.

How to change Wi-Fi network?

Press and hold the configuration button for 5 seconds until the Wi-Fi indicator blinks in a cycle (two short, one long). Release, the device enters quick pairing mode. You can then re-pair it to a new network via the eWeLink app.

How to reset the device to factory settings?

Delete the device in the eWeLink app. This restores it to factory settings. You can also press and hold the configuration button for 10 seconds until the indicator blinks rapidly.

What safety precautions should be taken?

Always cut off power before installation or maintenance. Contact a qualified professional. Avoid any contact with water. Respect the maximum loads indicated (10 A per channel, 15 A total). Do not use in damp environments.

Does the device work with 5 GHz Wi-Fi?

No, the device only supports 2.4 GHz Wi-Fi (IEEE 802.11 b/g/n). Make sure your router broadcasts a 2.4 GHz network for pairing.

How to control the device via LAN?

The device supports control via LAN (local network). In the eWeLink app, enable the 'LAN Control' option in the device settings. You will then be able to control it even without an Internet connection.

Common Problems

Q: Why my device stays "Offline"?

A: The newly added device needs 1 – 2mins to connect Wi-Fi and network. If it stays offline for a long time, please judge these problems by the blue Wi-Fi indicator status:

1. The blue Wi-Fi indicator quickly flashes once per second, which means that the switch failed to connect your Wi-Fi:

① Maybe you have entered a wrong Wi-Fi password.
② Maybe there's too much distance between the switch your router or the environment causes interference, consider getting close to the router. If failed, please add it again.
③ The 5G Wi-Fi network is not supported and only supports the 2.4GHz wireless network.
④ Maybe the MAC address filtering is open. Please turn it off.

If none of the above methods solved the problem, you can open the mobile datanetwork on your phone to create a Wi-Fi hotspot, then add the device again.

1. Blue indicator quickly flashes twice per second, which means your device has connected to Wi-Fi but failed to connect to the server.

Ensure steady enough network. If double flash occurs frequently, which means you access an unsteady network, not a product problem. If thenetwork is normal, try to turn off the power to restart the switch.
