Why can I only control my device when I connect to my home Wi Fi, but not 4G and other Wi Fi?
“ If you can control the device only when you connect your home Wi Fi, but you can't control it when you use 4G or other Wi Fi, it means that there is a problem in the connection between your home router and the external network, resulting in the device can't communicate with our cloud service (such as DNS or UDP forwarding problem, for details, please contact your network operator or router after-sales service) It can operate normally only under the LAN (when you connect to your home's Wi Fi, you use the LAN to control the device). Please check the connection between your router and external network, and try again after making sure it is unobstructed.
If the device is normally online, please check whether your mobile phone has permission to open the mobile data application on the app:
Iphone:settings - cellular network - find the corresponding app - turn on cellular network.
Android phone: settings - Traffic Management - Application Networking - find the corresponding app - open mobile data. "
