When the device is connected, it can be controlled at the same location, but cannot be remotely controlled by the phone when moved to another location or other network.

If the device needs to connect to the network, it is necessary to ensure that the physical switch of the lamp is open, and then the lamp can be controlled with the App. However, when it is powered off, the lights and the App will lose connection, so the light turns into an ordinary device. When the power is reconnected, if the light’s physical switch has been turned "on" before, then the light will turn on automatically.
