Does the mobile phone have to be on the same network (Wi Fi) as the device to control it?

"For the first time, mobile phones and devices must be placed in the same Wi Fi network;

After connecting the device to the network with Wi Fi, the mobile phone can switch to other network control;

Please make sure that the device must be connected to the Wi Fi all the time before the app can be used for normal linkage.

Note: 2.4G network is needed to add device networking. "
