请确认您的Wi-Fi当前连接外网是否稳定、正常。如时好时坏，频繁出现这种双闪
情况，说明您的网络不稳定，并非产品原因，如网络正常，请断电进行重启。
常见问题
问：设备添加成功后，显示离线，无法控制？
答：设备刚添加成功后，需要1-2分钟时间连接您的路由器并连网。如果长时间还是显
示不在线，请根据Wi-Fi蓝色指示灯的状态来判断：
1. 蓝灯1秒快闪一下：说明设备没有连上您的Wi-Fi。
① 可能是Wi-Fi密码输入不正确.
② 可能是设备离您的路由器太远，信号太弱，或环境有干扰。请先将设备靠近
路由器，如无改善，重新添加一遍.
③ 设备不能识别5G的Wi-Fi，请选择2.4G的Wi-Fi重新添加.
④ 检查您的路由器后台是否开启MAC地址过滤，如有，请关闭。

Common Problems
Q: Why my device stays “Offline”?
A: The newly added device needs 1 - 2mins to connect 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:
Maybe you have entered a wrong Wi-Fi password. ①
Maybe there's too much distance between the switch your router or the environment ②
causes interference, consider getting close to the router. If failed, please add it again.
The 5G Wi-Fi network is not supported and only supports the 2.4GHz wireless network. ③
Maybe the MAC address filtering is open. Please turn it off. ④
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 the product problem. If the network is normal, try to
turn off the power to restart the switch.
