Common Problems
Q: Why my device stays "Offline"?
A: The newly added device needs 1–2mins to connect the router
and Wi-Fi. If it stays offline for a long time, please check these
problems by the blue Wi-Fi indicator status:
1. The blue Wi-Fi indicator quickly flashes once per second, which
means that the device failed to connect your Wi-Fi:
1-1.Maybe you enter a wrong Wi-Fi password.
1-2.Maybe there's too much distance between the device and
your router or the environment causes interference, consider
getting close to the router. If failed, please add it again.
1-3.The 5G Wi-Fi network is not supported and it only supports
the 2.4GHz wireless network.
1-4.Maybe the MAC address filtering is open. Please turn it off.
If none of the above methods solved the problem, you can
open the mobile data network on your phone to create a
Wi-Fi hotspot, then add the device again.
2. Blue indicator quickly flashes twice per second, which means
the device has connected to Wi-Fi but failed to connect to the
server.
Ensure steady enough network. If double flash occurs frequently,
which means you access an unsteady network, not a product
problem. If the network is normal, try to turn off the power and
restart the device.
