RF Remote Controller Pairing
The 4CHPROR3 supports the remote controller with 433.92MHz frequency brand to turn on/off, and each channel can learn it independently, which is local short-range wireless control not Wi-Fi control.
Pairing Method:
Long press the channel switch button to be paired for 3 seconds until the Wi-Fi LED indicator turns red and "quickly flashes once" and release, then short press the button to be paired on the remote control. If the Wi-Fi LED indicator turns red and "quickly flashes once", it indicates that the pairing is successful.
Clearing Method:
Long press the channel switch button to be cleared for 5 seconds until the Wi-Fi LED indicator turns red and "quickly flashes twice" and release, then short press the button to be cleared on the remote control. If the Wi-Fi LED indicator turns red and "quickly flashes once", it indicates that the code is cleared.
Switch Network
If you need to change the network, long press any pairing button for about 5 seconds until the Wi-Fi LED indicator changes in a cycle of two short and one long flash and release. Then, the device enters quick pairing mode and you can pair again.
Factory Reset
Deleting the device on the eWeLink app indicates you restore it to factory setting.
Common Problems
Q: Why my device stays “Offline”?
A: The newly added device needs 1-2 minutes to connect to Wi-Fi and network. If it stays offline for a long time, please judge these problems by the blue Wi-Fi indicator status:
- The blue Wi-Fi indicator quickly flashes once per second, which means that the switch failed to connect your Wi-Fi:
- Maybe you have entered a wrong Wi-Fi password.
- Maybe there's too much distance between the switch and your router, or the environment causes interference. Consider getting close to the router. If failed, please add it again.
- The 5G Wi-Fi network is not supported; it only supports the 2.4GHz wireless network.
- Maybe the MAC address filtering is open. Please turn it off.
- Blue indicator quickly flashes twice per second, which means your device has connected to Wi-Fi but failed to connect to the server. Ensure a steady enough network. If double flash occurs frequently, it means you are accessing an unsteady network, not a product problem. If the network is normal, try turning off the power to restart the switch.
