The Community Energy Management System (CEMS) with IEEE1888 standard comprises buildings with metering systems and gateways (GW), which are linked to the system for efficient data management, and wireless systems installed in various places, which ZigBee is mostly used with the limitation only on short-range communication. Therefore, this paper presents the system development that extends the transmission from within ZigBee range to LoRa through aggregator (AG) and enables the transmission to be forwarded to the system with IEEE 1888 standard. The test results can be divided into 3 parts as follows: (1) Received Signal Strength Indicator (RSSI). For ZigBee, RSSI value increases from 5 to 20 meters upon an additional repeater is installed within the building. For LoRa, the maximum coverage in the test area reaches 573 meters with RSSI value equal to -95.1 dBm. (2) AG test. The result finds that in the case of data transmission is consistent with the period of 700 milliseconds and higher, the success rate is 100%. However, in the case of random transmission, the success rate is only 60%. (3) GW test, which is conducted by comparing the hop between GW and server. For the distance of 1 hop, the Round Trip Time (RTT) value does not exceed 100 milliseconds. Nevertheless, for the distance of 18 hops, the RTT value increase more than 4 times. Consequently, the tests in this research can be used as a guideline for design and development to optimize the future system extension.
