1. My device has added successfully, but stays “Offline”.
Answers: The new added device need 1-2 min to connect to your router and the Internet. If it stay offline for 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 router. The reason may be you have entered wrong WiFi password or your device is too far away from router, which causes a weak WiFi signal. The device can not be added to the 5G-wifi-router,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 device has connected to router and server, but failed to be added to 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 router but failed to connect to server. Then please confirm your WiFi router works normally.
2. Why the APP can not find the device in paring status?
Answers: That’s because of your phone’s cache. Please close the Wlan of 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.
