  1. 1stgeneration Sonoff models enter into pairing status:

Press and hold the pairing button on Sonoff, the led indicator will start to blink steadily.

This means the model has entered into pairing status, you can add it to your account. This is AP pairing way for 1st generation Sonoff models, including Sonoff Basic, Sonoff RF, Sonoff Slampher, Sonoff SV, Sonoff S20, old version 1 chnl inching/self-locking smart switch.

 

  1. 2ndgeneration Sonoff models enter into pairing status:

Press and hold the pairing button on Sonoff, the led indicator will start to blink 3 times and repeat.

This means the model has entered into pairing status, you can add it to your account. This TOUCH pairing way for 2nd generation Sonoff models. Except the 1st generation models (Sonoff Basic, Sonoff RF, Sonoff Slampher, Sonoff SV, Sonoff S20, old version 1 chnl inching/self-locking smart switch), all other models belong to the 2nd generation.

Please note that some special models may not blink in this way, but you still need to choose TOUCH pairing icon. The special models include: Sonoff Hum, Sonoff LED, Sonoff B1.

 

  1. The Sonoff model failed to connect to your router: 

The LED blinks once every 2s, and the device is offline, it means it failed to connect to your router.

There are some reasons causing this problem:

a. The WiFi strength is weak. Your router is too far away from your Sonoff model, and there may be some interference in the environment.

To solve it, please take your Sonoff close to the router. If the problem still exists, please cut off the power of Sonoff, delete the device from your account. Power it up and re-add.

b. Make sure you are not using the 5G WiFi. If you are connecting to 5G WiFi, please delete the device and re-add via 2.4G WiFi. Some WiFi Hue/Bridge may not compatible, this is rare.

c. Make sure your router settings don’t open the MAC address filter.

d. One normal router usually supports about 10-15 devices(including phone, PC, tablet, and all other devices that connects to the same router). Please make sure the number of devices currently connecting to your router doesn’t exceed its max limit.

 

  1. The Sonoff model has successfully connected to the server, but hasn’t been added to the user’s account:

Usually, there are two reasons lead to this result:

a. The owner has deleted it from the account, it doesn’t belong to any accounts now, but the Sonoff still recognize the previous WiFi.

Solution: Please power off the Sonoff and power it up, then wait for a while. If the device is still offline, please delete it and re-add.

b. During adding process, the app has completed the communication between smartphone and device, the device has obtained WiFi password, but when binding it to the user’s account, the network is interrupted.

Solution: Please power off the Sonoff and power it up, then wait for a while. If the device is still offline, please delete it and re-add.

 

  1. Failed to connect to the server. Network interrupted or DNS cannot resolve the address.

The LED indicator quickly blinks twice and repeats, which means the device has connected to the router but fail to connect to the server.

a.Unable to Visit the Internet

If the extranet cannot be accessed, then use your phone or PC to visit the Internet. If successful, try to connect your device again.

If you have stopped paying Internet fee or extending your network service, you can’t visit the Internet.

b. Bandwidth Occupied

You may have downloaded too many files at the same time, which occupied most of the bandwidth, thus your device did not have enough bandwidth to connect to the server. If so, please stop downloading and try to re-add your device.

c.More than one router with the same SSID (name)

You may have more than one router with the same name, and your device may have connected to the non-networked one. In this case, you should reset your router name and choose the networked one to connect. Then try to connect your device again.

d. More than one DHCP server on one network

There may be errors existing between router topology. In this case, please check the connection way between routers, then try again.

e. ARP Attacked

If you have checked all above and found them no problems, maybe some terminal of the local area network you are locating has affected ARP virus. We suggest you to manually bind gateway and MAC address, then try again.

f. Firewall Settings

You may have opened firewall or some security software. In this case, please temporarily close them and try to connect the device again.

g. DNS Server Inaccessible

After making all above checks and finding them no problems, the possible problem should be DNS error. Please manually change DNS server address and try again.

After making all above checks and find no problems but still failed, the possible problem should be DNS error. Please manually change DNS server address to 119.29.29.29. Then try to re-add your device.

h. IP address conflict

Please close all other connections that connect to the router. Then try to re-add your device.

You can also ping our server address on your computer. Please select the server address according to your location. Then send the result to our support. If you don’t know how to ping, please check this post.
