The goal was to implement a submetering solution that could:
– Ensure consistent and accurate hourly readings in a densely populated environment;
– Manage a large number of meters across multiple towers using minimal infrastructure;
– Provide individual consumption data and early anomaly detection at low operational costs.
Located in Belo Horizonte, Brazil, the residential complex consists of 682 apartments, distributed across 6 towers, each with 14 floor.
Each floor is equipped with 8 water meters using wMBus communication.
To capture data, only one LegitFix data concentrator—developed by WiserMeter—was installed in a common area.
Despite the technical challenge, the system successfully captured one reading per hour from every meter, totaling 491,040 readings in April 2025 alone, all processed automatically by the platform.
– Unmatched Reliability: Continuous data capture with no failures or interruptions for over 7 years;
– Scalable Efficiency: All 682 apartments monitored using a single data concentrator;
– Intelligent Alerts: The platform automatically detected leaks in 18 different units, notifying residents in real time;
– Low Cost, High Value: Entire solution delivered for less than $1 per apartment per month.
This case proves that cutting-edge technology doesn’t have to be expensive to be effective. With WiserMeter, submetering becomes a strategic tool for fair billing, resource conservation, and proactive maintenance—at scale and at a price point that makes sense.
