After installing the smart speaker, I found that the socket is behind the sofa! Or the speaker can only be placed in a corner! The whole house WiFi is dead, and the surveillance camera is frequently disconnected; the whole house intelligence is not sensitive, no response, and the scene is not executed; the smart installation is not working well, and I want to change it back to the ordinary one, but I found that there is no control line at all and it cannot be changed! These rollover scenes are staged every day; smart home cannot be achieved by buying a few devices, and the core secret is hidden in the wiring planning in the early stage of decoration.
