A boarding house, where multiple rooms are occupied by different individuals, faces challenges in managing electricity costs and payments due to varying consumption and different lengths of stay. To address this, a device was developed to monitor each tenant's electricity usage and integrate with the Internet of Things (IoT) via an Android application. This system utilizes key components, including the ESP-01 microcontroller and the PZEM-004T module, allowing tenants to track their electricity consumption, check remaining token balances, and make payments using Midtrans. The landlord can also monitor the electricity usage of each room, which simplifies the overall management of electricity consumption. Testing data revealed that the device's sensor accuracy is generally reliable, though there are slight discrepancies compared to standard measurement tools. In room 1, the sensor's current measurement has an average error rate of 0.247%, while in room 2, the error rate is just 0.007%. For voltage measurements, room 1's sensor shows an average error rate of 0.062%, and room 2's sensor shows 0.045%. Power measurement accuracy also varies, with room 1 showing a 0.561% error rate and room 2 showing a 0.675% error rate. Overall, the sensor demonstrates satisfactory accuracy, with room 2 performing slightly better.
