現今面臨能源需求增加的情況下，許多人積極採取其他發電設施來增加電量；然而，除了增加發電量，節約能源也是一種方法。在時下的電力供需模型中，消費者本身就可被視為一個具有潛力的虛擬發電廠，透過適當的能源管理方法能節約能源進而降低限電風險，並且為消費者降低電力成本的支出。目前大量能耗設備的資訊分散而無法加以控管，如果能將設備的資訊與用電消耗加以整合至一個平台並妥當管理，我們相信能大幅地增加能源的使用效率，並減少冗餘的用電消耗。在本研究中，我們因此設計與實作了一個低成本並可大量部署的智慧閘道器，對內可收集資訊與控管設備，對外可即時推播資料於雲端平台；消費者可以藉由雲端平台查看用電與遠端管理設備，並且可以透過視覺化圖表理解自己的用電情況來提升能源使用率。

Nowadays, when facing the increasing energy demand, many people attempt to generate more energy with alternative approaches. Nevertheless, energy conservation is a more feasible solution. In a modern demand-supply model for electricity usage, consumers cane be regarded as a virtual power plant. With appropriate energy conservation approaches, the energy crisis can be avoided and the expense can be significantly reduced for electricity consumers. At present, the information of numerous energy-consuming devices information is distributed and thus cannot be effectively managed. Once the device information and electricity consumption data can be integrated into a platform, it is believed that the energy efficiency can be greatly raised by actively reducing redundant power consumption. In this work, we design and implement a low-cost gateway that can be deployed in a large scale for energy management purposes. This gateway collects data from devices and controls these devices. Moreover, usage data can be pushed to a cloud platform immediately by this gateway. Then, consumers can easily get their consumption report, remotely manage their devices, and understand their energy usage patterns.
