Common Problems

Q: Why does my device stay “Oﬄine”?
A: The newly added device needs 1 – 2mins to connect to Wi-Fi and network. If it stays oﬄine for a long time, please judge these problems by the blue Wi-Fi indicator status:
1. The blue Wi-Fi indicator quickly ﬂashes once per second, which means that the switch failed to connect your Wi-Fi:

① Maybe you have entered the wrong Wi-Fi password.
② Maybe there’s too much distance between the switch your router or the environment causes interference, consider getting close to the router. If failed, please add it again.
③ The 5G Wi-Fi network is not supported and only supports the 2.4GHz wireless network.
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 your device has connected to Wi-Fi but failed to connect to the server.
Ensure a 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 to restart the switch.
