5. Problems and solutions
Read the detailed FAQ on Itead Smart Home Forum.
1. My device has added successfully, but stays “Offline”.
Answers: The newly added device need 1-2 min to connect to your router and the Internet. If it stays offline for a long time, please judge the problem by the green led status:
1.1. Green led quickly blinks one time and repeats, which means device failed to connect to the router. The reason may be you have entered wrong WiFi password or your device is too far away from the router, which causes a weak WiFi signal. The device can not be added to the 5G-wifi-router WLAN, only the 2.4G-wifi is OK. At last, make sure that your router is MAC-open.
1.2. Green led slowly blinks one time and repeats, which means the device has connected to router and server but failed to be added to the device list. Then power on the device again, if it still not working, just add the device again.
1.3. Green led quickly blinks twice and repeats, this means the device has connected to the router but failed to connect to the server. Then please confirm your WiFi router works normally.
2. Why the APP can’t find the device in pairing status?
Answers: That’s because of your phone’s cache. Please close WLANof your phone then open it after a minute. At the same time, please power off the device if you can, then power up to try again.
3. My WiFi is expired, can I connect the devices to LAN? Can my phone be directly connected to device hotspot?
Answers: Currently eWeLink does not support LAN or directly connect to deceive hotspot. All devices must be connected to the router, thus they can communicate with the Internet cloud server.
4. The green led keeps off, even if the device is powered on. Press the button but the device does not work.
Answers: The circuit may be broken, please send it back for testing. Return shipping postage and packaging will be at buyer’s expense, if the device is damaged by the buyer, and the buyer should bear extra repair cost.
