Frequently Asked Questions - Dual R3 Sonoff

How to reset the Dual R3 device to factory settings?

To reset, delete the device in the eWeLink app. This restores factory settings automatically. You can also press and hold the configuration button for 5 seconds until the Wi-Fi LED blinks (two short blinks then one long) to enter pairing mode.

How to put the device into pairing mode?

After powering on, the device automatically enters Bluetooth pairing mode for 3 minutes. Otherwise, press and hold the configuration button for 5 seconds until the Wi-Fi LED blinks in a cycle of 'two short, one long', then release.

What to do if the device remains offline?

Check that Wi-Fi is 2.4 GHz (5 GHz is not supported), the password is correct, the device is close to the router, and MAC filtering is disabled. If the LED blinks twice rapidly, the network is unstable. Restart the device and router.

How to choose the operating mode (switch, motor, counter)?

In the eWeLink app, after pairing the device, go to Dual R3 settings and select the mode corresponding to your connected device: switch (push button or toggle), motor (momentary switch), or counter.

Can I use a physical switch with the Dual R3?

Yes, connect a physical switch to the S1 and/or S2 terminals. Then in the eWeLink app, select the appropriate mode (momentary or toggle switch) for proper control.

What is the maximum load per channel and total?

Each channel supports up to 2200 W / 10 A, and the total load must not exceed 3300 W / 15 A. For motor loads, the limit is 240 W / 1 A.

How to connect two switches for two-way switching?

For two-way control, connect two SPDT switches to the S1 and S2 terminals, then set the mode to 'edge' in the eWeLink app. Follow the wiring diagram provided in the manual.

Does the Dual R3 work with 5 GHz Wi-Fi?

No, the device only works on 2.4 GHz Wi-Fi network (IEEE 802.11 b/g/n). Make sure your router broadcasts this network.

How to change Wi-Fi network?

Press and hold the pairing button for 5 seconds until the Wi-Fi LED blinks in a cycle of 'two short, one long'. Release, then the device enters pairing mode. Use the eWeLink app to reconnect to a new network.

What do the different Wi-Fi LED blink patterns mean?

- Fast blinking (one long, two short): quick pairing mode. - Solid: successfully connected. - Fast blink once: cannot find router. - Fast blink twice: connected to router but not to server. - Fast blink three times: firmware update in progress.

Operating Instruction

1. Power off

To avoid electric shocks, please consult the dealer or a qualified professional for help when installing and repairing! Please do not touch the switch during use.

2. Wiring instruction

Motor mode:

① Momentary switch:

Connect to S1 or S2 for smart control of connected devices; connect to S1 and S2 for two-way smart control.
② Dual relay momentary switch/3-gang rocker switch:

Light fixture wiring instruction:

① To enable dual relay control, S1 and S2 are required to connect the push button switch in the pulse mode or the rocker light switch in the edge mode:

② Connect SPDT switches in the edge mode to reach double two-way control:

③ Connect dry contact sensors in the following mode:

Make sure the neutral wire and live wire connection is correct.
The device still works normally if no a physical light switch is connected to S1/S2.
If S1/S2 is connected to a physical light switch, the corresponding working mode is required in eWeLink APP to select for normal use.

3. Download the eWeLink APP

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 2 seconds, 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 2 seconds, 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.
