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

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.

A person is sitting at a wooden table in a bright room with lots of green plants in the background. They are wearing a white blazer and white shirt and are holding a smartphone in both hands, as if reading a message or working on a task. There is a tablet on the table, which is switched off and reflects the light in the room. The atmosphere appears calm and focused, enhanced by the natural light coming in from the side. The scene conveys the impression of a modern working environment where digital devices are used to efficiently complete professional tasks or prepare for a conversation or meeting.

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:

Fully meter-agnostic - integrates all major brands and models; no rip-and-replace, no vendor lock-in
Multi-protocol support - M-Bus, wireless M-Bus, LoRaWAN, GPRS and 4G LTE - whatever your building requires
Hourly automated reads - data transmitted every hour, replacing manual visits with real-time certainty
MDMS as the billing engine - consumption data feeds directly into ista’s automated billing platform, eliminating multiple manual steps
ESCO-grade MV capability - the same MDMS platform powers our independent Measurement & Verification reporting for performance contracts
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.

From isolated meter to centralised intelligence. Here’s how we do it.

1. 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.

2. 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.

3. 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.

4. Automated Data Collection
Meter data is transmitted automatically every hour. No site visits. No manual reads. No end-of-month scramble.

5. 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.

6. 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.

From isolated reads to operational intelligence. One system. One accountability.

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.
