Problems solved by technology

Home automation heretofore is either very limited, to basic tasks such as remote control of light dimmers and switches, or it involves complicated, expensive, custom hardware and software The known home automation systems have very limited “intelligence” and awkward interfaces.
It is well known that harmonic interference on AC power lines causes heat loss inefficiencies, and undue wear on equipment such as transformers.
Harmonics are caused by non-linear loads, such as typical light dimmers, because they actively switch the power on and off to adjust the light level, as distinguished from a passive regulator such as a potentiometer or rheostat which, although resistive and therefore linear, is highly energy inefficient.
Passive solutions, such as filters, are known for reducing harmonic distortion, but they have limitations and also dissipate energy.
That solution, however, is not applicable to the usual single-phase household circuit.

Example

[0024] Nomenclature Note: In the provisional application, we used the term “Control Panel” to refer to “microprocessor based electronic device, capable of running operating systems which supports the wireless protocol, graphical user interface, touch screen functionality . . . ”. (Provisional page 3.) In the present application, we will instead use the term “central controller” to refer to various devices and embodiments functionally similar to what was previously called the “Control Panel”. This is to avoid confusion as the typical Central Controller, in accordance with some embodiments of the invention, will itself include a front panel or control panel that provides an interface to the controller.

[0025] Thus “control panel” will be used herein consistent with its ordinary meaning. For example, in one preferred embodiment, a central controller is disposed in a standard electrical box, and the front panel of the central controller is installed over it, similar to a conventional light

Abstract

A central controller (FIG. 1B, FIG. 2, FIG. 4) is disclosed to enable home and commercial automation for automatic, remote control of a wide variety of lights, appliances, HVAC (FIG. 3, FIG. 5) and other systems utilizing a wireless distributed network. The central controller preferably employs a standard CPU and embedded operating system software. Graphical (FIG. 2) and audio (FIG. 4) user interfaces can be implemented. Harmonic distortion due to non-linear AC loads (FIG. 8) are mitigated in single-phase circuits through intelligent control of the loads (FIG. 9) and/or through intelligent complementary control of linear loads (FIG. 10).
