Shenzhen Sonoff Technologies Co., Ltd.
布线规范：
1.总线⻓度合计不超过100m。
2.在同⼀总线系统中，使⽤同种规格线材。
3.尽量减少线路中的接点。接点处确保焊接良好，包扎紧密，避免松动和氧化。
4.采⽤菊󷒤链⽅式，杜绝星形连接和分叉连接。
5.485总线屏蔽层单端接地。
6.󲶽󸃓时，将总线末端设备的终端电阻开关切换为打开状态(其它设备该开关必须为关闭状态)。
线材选择：
使⽤两芯屏蔽双绞线(RVVSP)，铜制线芯≥0.2mm²。
主机重新配对
恢复出⼚设置
在eWeLinkApp端“删除设备”，设备即恢复出⼚设置。
主机以太⽹使⽤
主机必须先在易微联App端配⽹成功后再接⼊以太⽹使⽤，否则⽆法使⽤。
接⼊以太⽹后，主机优先使⽤以太⽹（Wi-Fi和以太⽹可以是不同⽹络）
更换主机的账⼾或连接的WiFi时，需重新配对添加。⻓按主机配对按键5秒直到⽹络指⽰灯呈“快闪状态”，
松开，此时设备进⼊蓝⽛配⽹模式，即可再次通过App蓝⽛配对添加设备。

常⻅问题
Wi-Fi设备与易微联APP配对失败
1.确保设备进⼊配对模式.
三分钟内设备没有配对成功，则⾃动退出配对模式。
2.请开启定位模式以及允许获取定位权限
配⽹前，请先开启⼿机的定位服务并允许获取定位权限，位置信息权限⽤于获取Wi-Fi列表信息。如果
“ 禁⽤”⼿机定位服务，设备将⽆法添加。
3.确保Wi-Fi运⾏在2.4GHz频段。
4.确保正确输⼊Wi-Fi⽹络名称和密码，且没有包含特殊字符。
密码错误是常⻅的配对失败原因。
5.配对时为了确保良好的信号传输，请将设备靠近路由器。
Wi-Fi设备“离线”问题
请根据Wi-FiLED指⽰灯状态检查以下问题：
LED灯每2秒闪烁⼀次，路由器连接失败。
1.输⼊不正确的Wi-Fi⽹络名称和密码。
2.确保你的Wi-Fi⽹络名称和密码没有包含特殊字符。例如，我们的系统⽆法识别希伯来语和阿拉伯语字
符，导致Wi-Fi连接失败；
3.路由器承载⼒较低。
4.Wi-Fi信号太弱。路由器和设备间隔太远，或者路由器与设备之前有障碍物导致信号⽆法传输。
5.确保设备的MAC地址在MAC管理的⽩名单中。
LED指⽰灯连续闪烁两次，服务器连接失败
1.确保⽹络连接正常。你可以通过⼿机或者电脑连接⽹络。如果连接失败，请检查⽹络。
2.路由器承载⼒较低。连接到路由器的设备超过最⼤值。请查看你的路由器可以连接的最⼤设备数量。
如果超过最⼤值，请删除个别设备或者更换⼀个承载⼒较⾼的路由器再次连接。
3.请联系你的⽹络服务供应商以确认服务器地址没有被屏蔽：
cn-disp.coolkit.cc(中国⼤陆)
as-disp.coolkit.cc(除中国外亚洲地区)
eu-disp.coolkit.cc(欧洲)
us-disp.coolkit.cc(美国)
如果以上⽅法均⽆法解决此问题，请在易微联APP上通过“帮助&反馈”提交你的问题。

SPM-Main Re-establish Pairing
SPM-Main Ethernet Usage
Only the main unit was paired successfully in the eWeLink App can it be connected to Ethernet
to work.
After connecting to Ethernet, the main unit will use Ethernet in preference (Wi-Fi and Ethernet can
be the different network).
The main unit need to be paired again when you replace its account or connected Wi-Fi.
Long-press the pairing button for 5s until the Signal Indicator flashed quickly and release. Now
the device had entered Bluetooth Pairing Mode, you can add the devices in the App through
Bluetooth Pairing again.
Factory Reset
Deleting the device on the eWeLink App indicates you restore it to factory setting.

The LED indicator flashes twice on repeated means you fail to connect to the server.
1. Make sure the Internet connection is normal. You can use your phone or PC to connect to the
Internet, and if you fail to access, please check the availability of the Internet connection.
2. Maybe your router has a low carrying capacity. The number of devices connected to the router
exceeds its maximum value. Please check the maximum number of devices that your router
can carry. If the number of connected devices exceeds the maximum value, please delete
some devices or change a lager router and try again.
3. Please contact your ISP and confirm our server address is not shielded:
cn-disp.coolkit.cc (China Mainland)
as-disp.coolkit.cc (in Asia except China)
eu-disp.coolkit.cc (in EU)
us-disp.coolkit.cc (in US)
If none of the above methods solved this problem, please submit your issue via help & feedback
on the eWeLink App.
Shenzhen Sonoff Technologies Co., Ltd. English
Common Problems
Fail to pair Wi-Fi devices with eWeLink APP
1. Make sure the device is in pairing mode.
The device will automatically exit the pairing mode if not paired within 3mins.
2. Please turn on the location service on your mobile phone and give the permission.
Before choosing the Wi-Fi network, the location service should be turned on and the permission
is given. Location information permission is used to obtain Wi-Fi list information. If you tap
"Disable", the device will not be added.
3. Make sure your Wi-Fi network runs on the 2.4GHz band.
4. Make sure you entered a correct Wi-Fi SSID and password, no special characters contained.
A wrong password is a very common reason for pairing failure.
5. You may get the device close to the router for a good signal transmission while pairing.
Wi-Fi devices "Offline" issues
Please check the following issues by the Wi-Fi LED indicator status:
The LED indicator blinks once every 2s means you fail to connect to the router.
1. Maybe you entered a wrong Wi-Fi SSID and password.
2. Make sure your Wi-Fi SSID and password don't contain special characters, for example, the
Hebrew, Arabic characters. Our system can't recognize these characters so that fail to connect
to the Wi-Fi.
3. Maybe your router has a lower carrying capacity.
4. Maybe the Wi-Fi signal strength is weak. Your router is too far away from your device, or there may
be some obstacles between the router and the device so that the signal transmission is blocked.
5. Be sure that the MAC of the device is not on the blacklist of your MAC management.
