What you can learn from blinking LED

What you can learn from blinking WiFi LED status indicator

Have you wondered what the blinking led on your smart home devices mean? You can easily find out what is going on with the connection between your smart device and your WiFi. Each blinking pattern suggests a unique status and the solution to any possible problem.

eWeLink support smart home devices usually blink in the cycle of 2 seconds repeatedly. Here are all the blinking patterns and what each of them mean.

Quickly blinks twice and remains on

快速亮两下后再长亮

In the cycle of 2 seconds, the LED indicator quickly blinks twice and remain on. This means the device is in quick pairing mode now. To pair device in this mode, you should make sure your smartphone connects a 2.4Ghz WiFi and open eWeLink app and tap 'Quick Pairing'.

在两秒的周期内，信号灯迅速亮两下后再长亮一次，这意味着设备正在处于快速匹配模式。在配网过程中，我们需要确保手机已经连接2.4GHz的WiFi，然后再打开易微联App选择“快速添加”。

亮灭频繁交替

Blinks constantly

In the cycle of 2 seconds, the LED indicator keeps blinking constatly. The WiFi smart device is in compatible pairing mode. To pair a device in this mode, open eWeLink app and tap 'Compatible Pairing'.

在两秒的周期内，信号灯以“一亮一暗”的形式频繁交替出现，说明WiFi智能设备正在处于兼容模式。在配网的过程中，我们需要在易微联App中选择“兼容模式（AP）”进行配网。

注意：GSM类设备出厂时，为防止未知情况的流量消耗会处于未激活状态，此时会出现这种信号。我们自行完成一次激活操作即可。

Note: To avoid unnecessary data consumption,

信号灯一直长亮

Solid on

Once a smart device of eWeLink ecosystem is registered successfully and gets online, the LED status indicator will remain solid on. In case that you find the LED distracting or disturbing, feel free to turn it off in the device settings in eWeLink app.

当易微联生态智能生态完成联网注册并正常可控后，设备的信号灯会处于长亮状态。如果我们不喜欢信号灯一直亮着，可以通过易微联App的设备设置页面进行关闭。

短暂亮一下后长灭

Blinks once shortly and off

During the cycle of 2 seconds, on condition that the LED indicator blinks once shortly and goes off a bit longer, that means the device lost connection with WiFi temporarily. The solution to this would be to verify if the router is working. Another potential reason would be that there are too many devices connecting the router. As a result, your eWeLink smart home device is forced offline. Try to disconnect some useless devices to fix it.

在两秒的周期内，如果设备信号灯出现“短暂亮一下后长灭”的情况，说明设备暂时失去WiFi连接。此时，我们需要检查一下路由器是否正常工作。另外，如果路由器设备连接数过多，也有可能导致智能设备被迫下线，请适当减少设备连接数。

注意：如果GSM类智能设备出现此信号，说明设备无法连接到网络供应商的网络，请把设备放在一个有信号的地方，或者检查设备的流量是否用完或者过期。

Note: If this blinking pattern happens to a GSM device, it means the device could not connect to carrier network. Please place it somewhere with strong signal or check if mobile data has expired or been exhausted.

短暂亮两下后长灭

Quickly blinks twice and remains off

Within the cycle of 2 seconds, when the LED indicator quickly blinks twice and remains off, eWeLink smart device has lost connection with the server.

Troubleshoot by going through the following solutions.

a) Check if external network is working.

b) When external network is OK, consult your carrier whether they have blocked the IP of eWeLink server.

c) In rare cases, be it natural or man-mande, unexpected situation such as earthquake or optical fibre being destroyed, could lead to server outage. Please wait for service to resume.

在两秒的周期内，如果设备信号灯出现“短暂亮两下后长灭”的情况，说明易微联智能设备已经跟服务器失去连接。
a）排查外网是否处于不可用状态；
b）在确定外网可用的状态下，咨询运营商是否对易微联服务器IP解析做了限制；
c）在极少数情况下，如果遇到海底光纤被挖断、地震等情况，服务器可能会收到波及，请耐心等待官方消息；

短暂亮三下后长灭

Blinks three times quickly and off

Anytime a device is updating firmware, the LED indicator will blink three times quickly and go off. Please wait until the update is completed.
