Abstract: Remote control of energy consumption is realized using a readily installable, flexible approach. According to an example embodiment of the present invention, a remote source communicates with a wireless controller for executing energy usage control. The remote source sends signals to the wireless controller via a gateway located near or, in one implementation, forming part of the wireless controller. In response to the signals, the wireless controller sets control settings for operating one or more of a variety of equipment types, such as a furnace, air conditioner, water heater or heat pump. With this approach, wired connections from the gateway to energy-consuming equipment do not necessarily need to be made in order to effect remote energy-consumption control. For instance, when used in connection with a controller wired to the energy-consuming equipment, the gateway need only communicate wirelessly with the controller and does not necessarily need to be coupled to the energy-consuming equipment.

Abstract: A security system and method of operation includes a wireless transmitter, a wireless receiver in wireless communication with the wireless transmitter, and a control panel. The transmitter transmits a wireless message, including a unique transmitter identification number, a status portion with a plurality of status bits, and a sequence count which it increments only when any one of the status bits changes. The receiver receives the wireless message, converts the wireless message to a digital message which is sent to the control panel. The control panel processes the digital message by extracting the sequence count and transmitter identification number. A previous sequence count associated with the transmitter identification number is retrieved from memory, and the sequence count from the message is compared with the previous sequence count. If the sequence count is not less than the previous sequence count, then the control panel processes the message.
