8. Problems and solutions
Read the detailed FAQ on the Itead Smart Home Forum. If the answers below do not solve your problem, please submit feedback on eWeLink.
1. My device has added successfully but stays "Offline".
Answers: The newly added device requires 1-2 minutes to connect to your router and the Internet. If it stays offline for an extended period, please assess the problem based on the green LED status:
- 1.1. Green LED quickly blinks once and repeats: This indicates the device failed to connect to the router. Possible reasons include entering the wrong WiFi password, the device being too far from the router (weak WiFi signal), or the device not being compatible with a 5G-WiFi router (only 2.4G-WiFi is supported). Ensure your router is MAC-open.
- 1.2. Green LED slowly blinks once and repeats: The device has connected to the router and server but failed to be added to the device list. Power cycle the device again; if it still doesn't work, try adding the device again.
- 1.3. Green LED quickly blinks twice and repeats: The device has connected to the router but failed to connect to the server. Please confirm your WiFi router is functioning normally.
2. Why can't the APP find the device in pairing status?
Answers: This is likely due to your phone's cache. Please close your phone's WLAN and reopen it after a minute. Simultaneously, restart your Sonoff SC device.
3. My WiFi is expired, can I connect the devices to LAN?
Answers: Currently, this product does not support LAN connections or connecting to a hotspot. All devices must connect to a router to communicate with the Internet via the cloud server.
4. The green LED stays off, even if the device is powered on. Pressing the button does not work.
Answers: The circuit may be broken. Please send the device back for testing. Return shipping postage and packaging will be at the buyer's expense. If the device is damaged by the buyer, the buyer will bear the extra repair cost.
