Elvaco CMe3100 M-Bus Gateway for Fixed Networks: A Flexible and Scalable Data Management Solution
Accurate Meter Data Collection Matters More Than Ever
In today’s world of intelligent infrastructure, accurate and efficient meter data collection is essential for energy management, operational efficiency, and sustainability. The Elvaco CMe3100 M -Bus gateway delivers a powerful and flexible solution for remote meter reading, data processing, and system integration, making it suitable for everything from compact building systems to complex IoT energy management networks.
What Is the Elvaco CMe3100?
The Elvaco CMe3100 is a fixed-network M -Bus gateway designed to support remote reading of up to 512 M -Bus or wireless M -Bus (wM-Bus) meters. It reads and processes meter data at scheduled intervals, then transmits it using a wide selection of communication protocols including HTTP, FTP, email, and MQTT.
The device is compatible with all M -Bus standard-compliant meters and integrates seamlessly with other Elvaco CMe and CMeX series devices, allowing for full system interoperability and ease of expansion.
Key Advantages of the CMe3100 Gateway
1. Flexible Licensing and Scalable Design
The CMe3100 features modular licensing, enabling users to scale functionality according to the size and complexity of their project. Licensing tiers support anywhere from 8 to 512 connected meters, with optional add-ons for advanced protocols such as Modbus, DLMS, REST, and JSON.
This ensures cost-efficiency by letting you pay only for the functionality you need — and expand capabilities later without replacing hardware.
2. Broad Integration with Industry Protocols
The gateway supports key protocols widely used in building automation and utility systems, including:
- BACnet
- Modbus
- DLMS/COSEM
- REST and JSON APIs
This enables seamless integration into:
- Building Management Systems (BMS)
- Energy monitoring dashboards
- Industrial automation platforms
Its flexibility makes the CMe3100 an ideal solution for commercial real estate, public utilities, smart cities, and industrial energy management.
3. Real-Time Data and Remote Configuration
With real-time remote meter reading, the CMe3100 empowers facility managers and system operators to act instantly on changes in usage or system behavior. The gateway also allows for full remote configuration and diagnostics, which reduces maintenance costs and accelerates troubleshooting without requiring onsite access.
4. Robust Design and Easy Installation
The gateway is housed in a durable polyamide enclosure, built for long-term performance even in demanding environments. It mounts easily on standard DIN rails and includes multicolor LED indicators that provide live diagnostics for:
- Ethernet connectivity
- USB status
- Error notifications
This design simplifies physical setup and supports efficient monitoring.
5. New Feature: MQTT Push Reports for Cloud Integration
With firmware version 1.15.0, the CMe3100 introduces Push Reports via MQTT, enabling direct, secure communication with cloud services and IoT platforms. Data is sent in CSV or JSON format, encrypted using TLS/SSL, ensuring secure and reliable transmission for real-time analytics.
This enhancement makes the gateway even more valuable for modern applications, including:
- Smart city data collection
- Real estate portfolio energy tracking
- Industrial facility energy analysis
