This research aims to design and implement an automated Telegram notification system to support the preventive maintenance of ESP8266-based generators. The research background is based on the needs of PT. Telkom Witel Central Sulawesi to receive real-time generator operational alerts without continuous manual monitoring.
The research method uses Research and Development (R&D) with the stages of needs analysis, system design, prototype implementation, and testing. The system is designed with ESP8266 as a notification controller, an ACS715 sensor for operation status detection, a ADS1115 module for reading accuracy, and the integration of Google Sheets and Telegram Bot API as an automated messaging medium.
The test results showed that the system managed to send 5 Telegram notifications in a row in a 5.4-minute test session, including "Running Reminder" and "Oil Change" alerts according to operational thresholds. The WiFi connection is stable with a status of "Connected (Reconnects: 1)" and the data is stored in Google Sheets with an HTTP 302 response. The system calculates the generator runtime automatically using the ESP8266's internal timer and sends timely notifications to the operator. The tests were conducted under limited conditions so long-term validation was required to measure the reliability of the system.
