Smart connected appliances can extend the operating hours of electrical appliances, avoiding peak energy costs and saving electricity for consumers. In addition, the system monitors energy consumption patterns and alerts consumers when home appliances require maintenance, helping to avoid downtime and costly repairs. The technology is implemented using wireless communication, metering and control techniques. Wireless communication methods that can be used include Wi-Fi®, PLCm or Zigbee®. With Zigbee communication, home appliances can obtain energy price signals through electricity meters or home energy management systems and send back energy usage measured by local metering circuits. The local controller can be used to condition the appliance and support the integration of a bypass or control circuit in the existing system controller/processor.
