Specifications

LAN Control

LAN control is a communication method to control devices directly without going through the Cloud, requiring your smartphone and device to connect to the same Wi-Fi. Operation notifications, operation records, firmware upgrades, smart scenes, device sharing, and device deletion are not supported when there is no external network connection.

Control Modes

Manual mode

Turn on/off the device through the App and device itself whenever you want.

Auto mode

Turn on/off the device automatically by presetting the threshold of temperature and humidity.

Auto mode setting: Set the threshold of temperature & humidity and effective time period; you can set up 8 automatic control programs in different time periods.

Note: Manual control and Auto mode can work at the same time. In auto mode, you can turn on/off the device manually. After a while, auto mode will resume execution if it detects changes in temperature and humidity.

Factory Reset

Deleting the device on the eWeLink app indicates you restore it to factory setting.

Common Problems

Fail to pair Wi-Fi devices to eWeLink APP

1. Make sure the device is in pairing mode. After three minutes of unsuccessful pairing, the device will automatically exit pairing mode.
2. Please turn on location services and allow location permission. Before choosing the Wi-Fi network, location services should be turned on and location permission should be allowed. Location information permission is used to obtain Wi-Fi list information. If you click Disable, you will not be able to add devices.
3. Make sure your Wi-Fi network runs on the 2.4GHz band.
4. Make sure you entered a correct Wi-Fi SSID and password, with no special characters contained. A wrong password is a very common reason for pairing failure.
5. The device should be close to the router for a good transmission signal condition while pairing.

Wi-Fi devices "Offline" issue

Check the following problems by the Wi-Fi LED indicator status:

The LED indicator blinks once every 2s means you fail to connect to the router.

1. Maybe you entered the wrong Wi-Fi SSID and password.
2. Make sure that your Wi-Fi SSID and password don't contain special characters, for example, Hebrew or Arabic characters, as our system cannot recognize these characters and then fails to connect to the Wi-Fi.
3. Maybe your router has a lower carrying capacity.
4. Maybe the Wi-Fi strength is weak. Your router is too far away from your device, or there may be some obstacle between the router and device which blocks the signal transmission.

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

1. Make sure the Internet connection is working. You can use your phone or PC to connect to the Internet, and if it fails to access, please check the availability of the Internet connection.
2. Maybe your router has a low carrying capacity. The number of devices connected to the router exceeds its maximum value. Please confirm the maximum number of devices that your router can carry. If it exceeds, please delete some devices or get a larger router and try again.

If none of the above methods solved this problem, please submit your request via help&feedback on the eWeLink App.
