A modular dimmer assembly, including a communications circuit configured to send and receive wireless communication, a control circuit configured to receive an AC input at a first pulse width and adjust the brightness of at least one lighting device, in response to the communications circuit receiving a signal, by producing an AC output at a second pulse width, a regulation circuit, controlled by the AC output, including a flyback switch mode power supply (SMPS) and a capacitor, wherein the flyback SMPS charges the capacitor and the control circuit monitors a voltage of the capacitor to determine the second pulse width, and wherein the modular dimmer assembly is a two-wire device.

Lighting dimmer module and method of calibration

One example embodiment relates to a water heater controller. The water heater controller includes an operating conditions circuit structured to receive temperature measurement signals indicative of temperatures over time of water in a tank of a water heater, and occupancy measurement signals indicative of whether individuals are present in an area proximate the water heater. A drift threshold circuit is structured to, in response to the occupancy measurement signals indicating that an individual is present or not present, define a plurality of drift threshold levels to trigger operation of a heating element of the water heater. A control circuit is structured to controllably operate the heating element based on the occupancy measurement signals and on the plurality of drift threshold levels.
