A strong IoT device management system should offer real-time monitoring, remote control, and secure updates. It should allow you to group devices and manage them easily. In water plants, this helps in managing pumps, valves, and smart meters together. Security is also important—it should protect devices from threats. Firmware updates should be smooth and wireless. With good device management, you reduce downtime and increase performance. It makes your IoT system smart, safe, and efficient.
