This paper proposes machine-to-machine device connectivity (M2M-DC) framework to enhance efficiency of smart metering system by controlling electrical devices in a building. Internet of Things (IoT) is a trend technology implemented in many areas, of which the utilization to enhance the efficiency of power consumption is significantly important. There are several smart metering solutions have been developed in recent years, however, they are silo solutions that pay a little attention to scalability. To ensure scalability, a framework that rules number of sensors, actuator and devices are required. M2M-DC is a proposed framework that connects the nodes with sensors and actuators to the backend system based on the rule set. Some experiments are performed to measure the effectiveness of the system. The results show that the M2M-DC framework can control energy consumption, achieving higher energy efficiency of 26.35%, regarding the rule set. Based on the Wilcoxon method, the significance of the increase of efficiency on power consumption is confirmed. The scalability of proposed framework is also verified by varying sensors, actuators and devices.
