A system for recording the use of electrical energy is needed to determine the amount of electrical energy that has been used. Industry, households, and electricity supply companies need this recording system for payment matters. The manual recording system uses an analog kWh meter and then the usage is recorded manually. In this study, an automatic recording system was created which was stored in a database. The system created for monitoring 3-phase electricity usage is one of the technologies used to determine the use of electrical energy in a place that can be done anywhere. One way to find out electricity usage is to use a digital kWh meter which stores electricity reading data in registers which will then be read using the RS-485 communication protocol or commonly called Modbus and processed by ESP32 then forwarded to ANTARES using the LoRa communication network ( LongRange). The research method used is the waterfall method which consists of observation, planning, design, implementation, and testing. Based on the results of the measurement accuracy test, the system is able to read data on the digital kWh meter exactly the same where the resulting error rate is 0% in voltage, current and power readings. In the LoRa network QoS test, the system has an average delay of 1189.9 ms and an average packet loss of 0.083%.
