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 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 not find the device in pairing 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 restart your device. 

3. My WiFi is expired, can I connect the devices to LAN? 

Answers: Currently this product does not support LAN  or cannot connect to the 
hotspot. All devices must be connected to the router, thus they can communicate with 

the Internet via the 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.
