Solution Overview

WiiNOT (https://wiinot.net) is a comprehensive smart water management solution combining advanced hardware and intelligent software. It features IoT-enabled water meters with wireless transmission (LoRaWAN, NB-IoT, LTE Cat-1) for real-time monitoring and automatic data logging. Its AI-powered platform offers leak detection, usage analysis, forecasting, and alert notifications through a centralized dashboard. The system integrates easily with building management systems via open APIs. Since 2018, over 50,000 units have been deployed by the Hong Kong Water Supplies Department and other institutions, achieving significant water savings, reduced labor costs, and progress toward sustainability goals.

Solution Highlights (4 Ables)

• Affordable: Low-barrier entry with customized annual packages starting at HKD 8,000, preventing catastrophic water damage, building structural decay, and high waste-water discharge costs.
• Measurable: Replaces static thresholds with an adaptively updated "normal water-use baseline" (e.g., matching the past 7 days' rolling average to exclude normal operational fluctuations). Eliminates false alarms by correlating flow rate with pressure, temperature, and velocity; performs Zonal Pinpointing using hierarchical "single meter < sub-district < regional" aggregated analysis.
• Actionable: Rapid physical installation backed by step-by-step video tutorials, allowing SMEs to deploy the system and extract traceable water-intensity data within 3 days.
• Scalable: Operates on a "Stream-Split" processing architecture (regular 30-min data saved on-site for batch upload; anomalies trigger immediate event-driven alerts). Utilizes a high-concurrency MQTT Publish-Subscribe protocol with intelligent message queuing and priority routing to manage networks with over 30,000 nodes without latency.
