Every Meter Read. Every Night Over Any Cellular Network.
GridX HES connects directly to DLMS smart meters over 2G to 5G cellular networks. It collects billing, load profile and event data, runs remote commands and firmware upgrades, and gives your team a built-in Smart Metering Operations Centre, from the first thousand meters to millions.

What is GridX HES?
GridX Head-End System (HES) acts as the communication layer between smart meters and utility applications. It enables reliable meter communication, secure data collection, remote meter management, and seamless integration with utility systems.

Smart Meter Communication
Enable reliable DLMS and PLC-based communication between smart meters and the Head-End System for efficient meter data exchange.

Secure Data Acquisition
Collect billing, instantaneous, load profile, and event data securely from connected smart meters through reliable communication workflows.

Remote Meter Management
Support remote meter configuration, settings, authentication, encryption, and operational management through the HES platform.

Utility-Ready Integration
Integrate meter data and communication workflows with utility applications using structured profiles, OBIS mapping, and standardized interfaces.
CELLULAR, EVERY OPTION
One Head-End For Every Cellular Technology In Your Estate
Smart meters stay in the field for 10 to 15 years, while networks change underneath them. 2G and 3G are being switched off, IoT networks such as LTE-M and NB-IoT are growing, and 5G RedCap is arriving for gateways.
GridX HES talks DLMS over IP, so it is independent of the radio underneath.
Mix technologies, operators and meter makes in one estate, and migrate meters from 2G to 4G or LTE-M without changing anything upstream.
Supports private APNs, static or dynamic IPs, meter-initiated push sessions and SIM or eSIM with multiple operators.
| Technology | Why Utilities Choose It | Typical Use |
|---|---|---|
| LTE Cat-M1 (LTE-M) Recommended | Low latency, higher data rates, strong indoor reach; handles dense urban meter clusters | New city rollouts, 15-min data, firmware upgrades |
| NB-IoT | Deepest indoor coverage and lowest power; built for small daily data | Basements, meter rooms, single-phase meters |
| 4G LTE Cat-1 / Cat-1 bis | Runs on today's widest 4G coverage; more throughput | Three-phase, CT, DT and feeder meters |
| 5G RedCap Future-ready | 5G-grade capacity at lower cost and power than full 5G | Gateways, DCUs, grid monitoring |
| 2G GPRS / 3G Legacy | Large installed base; networks being switched off | Existing meters, managed migration |
| Private LTE & private APN | Utility-controlled coverage and security | Critical sites, regulated networks |

Any cellular, one system
Not one or two radio types: 2G to 5G RedCap in one estate.
Operations centre included
No separate monitoring tools: SMOC is in the same console.
Silent meters found same day
Not at billing time: alarms, retries and field tickets.
2G switch-off, no re-buy
Move meters to 4G or LTE-M with no upstream change.
A Complete Head-End.With The Operations Centre Builtin.
Most head-end systems stop at collecting data and leave monitoring to separate tools. GridX HES runs the meters and the operation in one place, so your team sees problems before the billing cycle does.

Data Collection
SCHEDULED · ON-DEMAND · PUSHDelivers: complete daily data, on time, from every meter.

Security by Design
DLMS SECURITY SUITEDelivers: meter data and commands that cannot be read or forged.

Remote Commands
SINGLE · GROUP · BULKDelivers: fewer truck rolls for routine meter work.

Firmware & Configuration
OVER-THE-AIR CAMPAIGNSDelivers: meter fleets kept current without a site visit.

Events & Alarms
REAL-TIME PUSHDelivers: tamper and outage events the moment the meter raises them.

Multi-vendor & Open
STANDARDS-BASEDDelivers: freedom to buy meters from any DLMS manufacturer.

Scale & Availability
PILOT TO MILLIONSDelivers: the same performance at 2 million meters as at 2,000.

Smart Metering Operations Centre
24×7 NETWORK OPERATIONSDelivers: one control room for the whole AMI network, 24×7.
