AMI & Sub-Metering
A unified electricity, water, and gas sub‑metering solution delivering accurate consumption measurement, transparent billing, and data‑driven resource optimization for buildings and industrial facilities.
Overview
About AMI & Sub-Metering
The NET WIZARDS Sub‑Metering Solution provides precise, real‑time measurement of electricity, water, and gas consumption across residential, commercial, and industrial environments. By deploying utility‑grade meters, IoT gateways, and a cloud‑based analytics platform, the system enables owners, operators, and facility managers to gain full visibility into consumption at tenant, zone, equipment, or process level. This eliminates estimated billing, reduces disputes, and supports fair, transparent cost allocation.
With support for Modbus, M‑Bus, LoRaWAN, NB‑IoT, LTE, Ethernet, the solution integrates seamlessly into both new and retrofit projects. For industrial plants, the solution extends beyond billing to provide sectional energy intelligence across production lines, HVAC systems, compressors, boilers, cooling towers, and utility systems.
Operators can detect inefficiencies, identify abnormal consumption, track losses, and implement targeted energy‑management strategies. Powered by the Sub‑Metering Cloud Platform, users benefit from automated billing, tariff management, alarms, ESG reporting, and multi‑tenant dashboards, enabling organizations to improve sustainability, reduce operational costs, and build smarter, data‑driven industrial ecosystems.

Solution architecture diagram
How AMI & Sub-Metering works, from sensor to cloud platform
Electricity, water and gas consumption is read automatically at interval level, which removes manual reading visits and makes billing, loss investigation and tenant transparency possible from the same data set.

02
Wireless connectivity
Low power wide area networkLoRaWAN, NB-IoT or wired M-Bus
Meters already in place are read through their existing bus and converted, while new points use low power wide area radio. Both paths reach the same platform.
Gateways and network server
Gateways and protocol converters collect meter registers, apply decoding and time stamping, and buffer readings so no billing interval is lost during a communications interruption.
03
Cloud platform
Storage, rules and reportingPlatform services
Device management, secure ingestion, time series storage, rules and alerting, role based access and open interfaces for integration with the systems already in use.
- Interval consumption per meter, tenant and building
- Billing files and tariff calculation
- Loss and leak investigation by comparing bulk and sub meters
- Consumption benchmarking and anomaly alerts
- Meter health, missing read and tamper reporting
04

Questions
AMI & Sub-Metering questions we are asked most
- Can existing meters be used for automated reading?
- Often yes. Meters with an M-Bus, Modbus or pulse output are read through a converter and brought into the same platform as radio connected meters, which avoids replacing a whole meter estate.
- How often are readings collected?
- Interval reading is configured per project, commonly at fifteen minute, hourly or daily resolution depending on the tariff, the billing requirement and the meter type.
- How does sub metering help reduce losses?
- Bulk meter readings are compared against the sum of sub meters for the same zone, which exposes unbilled consumption and leaks. The platform highlights the difference so an investigation targets a specific riser, zone or connection.
