Sonoff S55 Wi-Fi Smart Waterproof Socket [4/21] Common problems

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 ②

environment 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 ③

wireless network.

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 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 press the “Reset Button” or turn off the power to

restart the switch.
