Device function

   • Add a wire to connect L1 to L2 on the wall switch following the manual, and the device will stay online even when you switch it off via the wall switch after "Magic Switch Mode" enabled.
   • The "Power-on State" will automatically be set to OFF, to make the "Magic Switch Mode" functional when enabled.
   • The "Magic Switch Mode" will automatically disable after your adjustment to the "Power-on State".

Note: Only compatible with mainstream brands of double pole Rocker switches. The rear-end light needs to be compatible with mainstream brands of LED, energy-saving lamps, and incandescent lamps ranging from 3W to 100W.
* This function also applies to dual-control lamps

2. Auxiliary overheating protection
   With the product built-in temperature sensor, real-time maximum temperature of the entire product can be detected and speculated, which prevents the product from deformation, melting, fire or live devices exposing in case of over-temperature.
   The device automatically cuts off the load when it gets too hot. To exit the overheating protection mode, simply press the button on the device after confirming that the load is functioning normally without any internal shorts, excessive power, or leaks.
   * Please note that this function only serves as auxiliary protection and cannot be used in place of a circuit breaker.

FAQ

Fail to pair Wi-Fi devices with the eWeLink App

1. Make sure the device is in pairing mode.
   The device will automatically exit the pairing mode if it is not paired within 10 mins.
2. Please enable location service and allow access to location permission.
   Before connecting Wi-Fi network, please enable the location service and allow access to the location permission. Location information permission is used to obtain Wi-Fi list information, if you "disable" the location service, the device cannot be paired.
3. Make sure your Wi-Fi works on 2.4GHz band.
4. Make sure to enter the Wi-Fi SSID and password correctly without special characters. Incorrect password is a common cause of pairing failure.
5. To ensure good signal transmission while pairing, please place the device close to the router.

The LED indicator flashes twice on repeated means the server fails to connect.

1. Make sure the networking is normal. Check the internet works well by connecting your phone or PC. If fail to connect, please check the availability of the Internet connection.
2. Please check the maximum number of devices that can be connected to your router. If your router has a low capacity and the number of devices connected to it exceeds the maximum, remove some devices or use a higher-capacity router.

If the above methods cannot help to solve the problem, please submit your problem to "Help & Feedback" on the eWeLink App

Wi-Fi devices are "offline"

1. Devices fail to connect to the router.
2. Entered the wrong Wi-Fi SSID and password.
3. Wi-Fi SSID and password contain special characters, for example, our system can't recognize Hebrew and Arabic characters, which causes Wi-Fi connections to fail.
4. Low capacity of the router.
5. Wi-Fi signal is weak. The router and the devices are too far apart, or there is an obstacle between the router and the device, which prevents the signal from being transmitted.
