A person is working at a desk in an office, pensively holding a pen in their hand while looking at a large monitor. Several windows with text-based content and coloured areas are open on the screen, suggesting analysis or development work. In the foreground, another screen is blurred, next to it are a keyboard and a coffee cup. The environment is warmly lit and looks like a focused workplace in a home office or study. The scene conveys focused work, digital information processing and a calm, professional atmosphere.
Every Meter. Every Building. One Platform.

Eliminate manual reading and automate billing

ista ME’s Meter Data Management System (MDMS) centralises consumption data from any meter brand, any protocol and any building type.

Giving you the real-time visibility to manage performance, not just monitor it.

Global expert. Regional leader.

200,000+ BTU sub-meters installed

Middle East pioneer integrating BTU meters on a single platform to scale

Fully meter-agnostic – works with all major brands and protocols

Data transmitted every hour – no manual reads, no end-of-month rush

Data you can’t see is a problem you can’t solve.

For utility providers, building managers and operators running large meter estates, the gap between what your meters know and what you can act on is where costs accumulate:

  • Manual meter reads that are slow, error-prone and impossible to scale across large portfolios
  • Mixed-brand meter estates with incompatible data formats - no single view, no reliable baseline
  • End-of-month billing rushes that create errors, disputes and strained tenant relationships
  • Performance issues (leaks, anomalies, inefficiencies) that go undetected for weeks or months
  • No audit trail for regulatory submissions, ESCO performance verification, or billing disputes

The problem isn’t the meters. It’s the gap between the data they collect and the decisions you need to make.

Not Just Connected. Managed. Analysed. Acted On.

ista ME doesn’t just collect meter data - we transform it into the operational intelligence that powers accurate billing, proactive maintenance and independently auditable performance reporting. All from one platform, under one contract.

What sets us apart:

  1. Fully meter-​agnostic – integrates all major brands and models; no rip-​and-​replace, no vendor lock-in
  2. Multi-​protocol support – M-Bus, wireless M-Bus, LoRaWAN, GPRS and 4G LTE - whatever your building requires
  3. Hourly automated reads – data transmitted every hour, replacing manual visits with real-time certainty
  4. MDMS as the billing engine – consumption data feeds directly into ista’s automated billing platform, eliminating multiple manual steps
  5. ESCO-​grade MV capability – the same MDMS platform powers our independent Measurement & Verification reporting for performance contracts
  6. Scalable by design – from a single building to a district-​wide network; new meters integrate without disruption

Faster and fairer. Upgrade to remote data collection with ista.

Take control with smart meter data at your fingertips.

Utility Providers

Optimising the network through intelligent data analysis.

The picture shows an older woman with a brown notebook in her hand, standing in a light-coloured office room with a glass front. She is wearing a creamy white jumper, several small gold necklaces and light brown suit trousers. she has grey shoulder-length hair and she is looking to the left and smiling. In front of her in the foreground is a table with a white model of a city with a tower block, several smaller houses and several wind turbines. the background is blurred, but you can make out the glass front, a white flower box and a corner of another desk.

Property Managers

Save time and increase operational efficiency for your properties with transparent energy consumption visibility.

A child sits on a sofa and writes on a piece of paper with a pen, as if doing homework or an exercise. Next to the child sits an adult in white traditional clothing, helping with learning by pointing to the screen of an open laptop. The laptop is blurred in the foreground, which puts the focus on the joint work. The bright, tidy environment looks like a living room or quiet work area. The scene conveys guidance, concentration and joint learning at home.

End-users

Gain control over your energy costs with transparent consumption data.

From isolated meter to centralised intelligence. One system. One accountability.

Site Assessment & Protocol Mapping:

We audit your existing meter estate (brands, models, communication protocols) and design the integration architecture. No unnecessary replacements. Maximum use of what you already have.

Gateway Installation:

M-Bus masters, LoRaWAN hubs, or 4G LTE modems are installed at building level, connecting every meter to the central platform via a secured M2M private APN network. Installed with zero disruption to live meter reading and billing.

MDMS Platform Setup:

ista’s enterprise-​grade MDMS is configured on your server or deployed cloud-​based, with interfaces built for third-​party meter brands. Every meter, every protocol, unified.

Automated Data Collection:

Meter data is transmitted automatically every hour. No site visits. No manual reads. No end-​of-​month scramble.

Validation & Anomaly Detection:

The platform flags errors, alarms, and anomalies in real time (low delta-T, high/low flow, tamper alerts, and meter faults) before they become billing problems or tenant disputes.

Billing, Reporting & MV Export:

Validated consumption data feeds directly into automated billing, energy performance reports and IPMVP-​aligned MV exports – everything needed for transparent operations, regulatory compliance, and performance contract verification.

A technician is working in a narrow technical room or basement corridor under a ceiling with several parallel metal pipes. He is wearing a blue safety helmet and a work jacket and is raising both arms to check or adjust a pipe or bracket above him. On the right, further installations such as ventilation ducts and cable ducts can be seen, while the walls are made of concrete or brickwork. The perspective looks along the pipes into the depths of the room and emphasises the technical infrastructure of the building.
