IoT Device Monitoring System
Data and alerts from more than eight device categories appear together, with reading history and connection status for operators.

IoT Device Monitoring System
This work brings more than eight device categories into operational dashboards. It covers water, electricity, and gas meters; nurse call systems; medical emergency alerts; emergency buttons; smart locks; vending machines; and factory controllers. Operators get information suited to their work.
Challenge
Devices use different ways of exchanging data. Water meters use Modbus, short-range wireless devices use BLE, and notifications arrive through MQTT or WebSocket. Operators need one view without understanding each device’s communication method.
Solution
I built data collection flows with consistent reading formats across devices. MQTT and WebSocket carry notifications as events happen. Modbus data is read periodically and mapped to meaningful values. BLE devices connect through gateways, while historical data is stored for reporting.
I mapped client workflows before building dashboards. Views reflect the information operators need, including update times and device connection health.
Impact
Operators no longer switch between separate tools simply to understand device conditions. In healthcare systems, important notifications arrive without waiting for the next scheduled reading. In factory monitoring, controller connection status is visible so old data is not mistaken for a recent reading.
Project device records support a scope of 500+ devices in systems I have worked on.
