A method and a device for joining a remotely controlled switching and current sensing AC device structured for attachment to standard and popular three way SPDT AC switches or cross DPDT AC switches and/or power outlets, such that the front wall plate of a single gang electrical box will cover the joined AC device with the manual switch or the AC outlet. The AC device is operated and communicates via lightguide or fiber optic cable using two way optical signals and via IR in air in line of sight and/or via RF in air. The lightguide is cascaded in series from one AC device to another and/or from a joint switch device to a joined AC outlet and to an optoport in front of an outlet socket for communicating the current drain and/or operation controls with the appliance, powered by the AC socket, via a lightguide included in the power cable with plug assembly of the appliance.
