Troubleshooting and FAQ1.What devices can i control with the Smart Plug?You can control lights, fans, portable heaters, and any small appliances in accordance with the Smart Plug’s specifications.2. What should I do when device configuration process has failed? You could: Check whether the Smart Plug is powered on or not. Check whether your mobile device is connected to 2.4 GHz WI-Fi network. Check your network connectivity. Make sure the router is working properly: If the router is dual-band router, please select 2.4G network and then add Smart Plug. Enable the router's broadcasting function. Configure the encryption method as WPA2-PSK and authorization type as AES,or set both as auto. Wireless mode cannot be 11n only. Check for Wi-Fi interference or relocate the Smart Plug to another location within the signal range. Check whether the router’s connected devices reach the amount limit.Please try to turn off some device’s Wi-Fi function and configure Smart Plug again. Check if router’s wireless MAC filtering functions in enabled. Remove the device from filter list and make sure the router is not prohibiting Smart Plug from connection. Make sure the password of your Wi-Fi network entered in App is correct when adding Smart Plug. Make sure the Smart Plug is in ready for App-Configuration; the indicator light is quick blinking blue [twice per second].Repeat the App-configuration process.Factory reset the Smart Plug and tries to add it again.3. Can I control device through 2G/3G/4G cellular networks?The Smart Plug and the mobile device are required to be under same Wi-Fi network when adding the Smart Plug for the first time. After successful device configuration, you can remotely control the device through 2G/3G/4G cellular networks.4. How can I share my device with family?Run the App CRESTIN, go to “ Profile ” -> “ Device Sharing ” -> “ Sent ” tap “ Add Sharing ”, now you can share the device with added family members.5.How to create a group?Run the CRESTIN, go to " Profile " -> " Create Group" Select the plugs you want to team up 1 Method 21.Enter the gateway function interface and choose to add a new device. 1 4 Made in China ˖ FCC WARNING This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
