AetherOS™ delivers high-performance Linux-based intelligence for gateways and DCUs such as AetherNEXUS™, while AetherRT™ provides deterministic, real-time responsiveness for devices like AetherEdge™ smart meters and AetherPulse™ sensors.
Both operating systems share:
- A unified security architecture
- A common DLMS/COSEM data model
- Consistent communication principles
- Native interoperability with AetherONE™
This alignment enables seamless operation from device to gateway to cloud.
Built on a hardened Linux distribution, AetherOS™ powers high-performance edge nodes and supports the full modular communication stack of AetherLink™.
System Capabilities
- Multi-threaded data acquisition and edge analytics
- Full DLMS/COSEM server functionality
- WAN/LMN module support (PLC, RF, LTE, Ethernet)
- Secure boot, image signing and encrypted storage
- VPN, IPSec, OpenVPN and TLS-secured APIs
- OTA firmware and module upgrades
- Local storage for LP, event logs and buffered data
Supported Communication
• PLC (G3, HS-PLC, Hybrid-PLC) • Wi-SUN • Zigbee • LTE/4G/NB-IoT • Ethernet • RS-485/RS-232/CAN
AetherOS™ turns gateways into intelligent edge processors capable of secure data handling, protocol translation, anomaly detection and autonomous decision-making—even during network disruptions.

AetherRT™ is a lightweight, deterministic real-time operating system engineered for long-term reliability (15–20 years) within embedded environments.
System Capabilities
- Deterministic task scheduling
- High-speed metrology loops
- Low interrupt latency
- Full DLMS/COSEM client stack
- Secure key storage and anti-tamper engine
- Power-fail-safe LP/event buffers
- Ultra-efficient memory performance
Typical FunctionsEnergy calculation
• Voltage/current sampling • Harmonic/PQ evaluation • Tamper detection • Event generation • Optical port communication
AetherRT™ ensures consistent, accurate and secure device behaviour—from metrology timing to event generation—across every deployed endpoint.
AetherOS™ and AetherRT™ are aligned by design to ensure uniform behaviour across gateways, meters, sensors and the cloud platform.
- AES-128/256 encryption
- DLMS HLS5 authentication
- Certificate-based security
- Protected key vaults
- End-to-end encrypted communication
A single object model is shared across:
- AetherEdge™ meters
- AetherPulse™ sensors
- AetherNEXUS™ gateways
- AetherONE™ cloud services
AetherRT™ communicates natively with AetherOS™, and AetherOS™ communicates natively with AetherONE™—ensuring consistent performance across all interfaces.
Data Exchange Flow
- AetherRT™ produces DLMS objects
- AetherOS™ polls devices through its DLMS client-server
- Data is validated, aggregated and prepared
- Secure APIs deliver structured data to AetherONE™
Supported Protocols
REST/HTTPS • DLMS/COSEM • Binary serial protocol • MQTT (optional)
This consistent flow simplifies integration, accelerates device deployment and ensures dependable data movement across the grid.
