GridLogic Unveils AI-Enhanced Single-Phase DIN-Rail Energy Meter

GridLogic SA, the Swiss metering-technology specialist, today announced commercial availability of the GridLogic OnePulse, a next-generation single-phase DIN-rail energy meter that embeds adaptive machine-learning firmware to deliver revenue-grade accuracy, predictive health analytics, and frictionless integration with both legacy SCADA and cloud-native energy platforms.

While the global installed base of DIN-rail meters has surpassed 400 million units, utilities and facility managers still wrestle with three chronic pain points: creeping measurement drift, opaque fault signatures, and the high cost of retrofitting connectivity. The OnePulse addresses all three through a patented dual-core metrology engine that continuously cross-checks its own calibration against a traceable on-board reference, automatically applying micro-corrections before drift exceeds 0.1 %—a figure independently verified by the Swiss Federal Institute of Metrology (METAS).

At the heart of the device sits a 24-bit oversampling sigma-delta converter paired with a second, ultra-low-power neural processing unit. Every 250 milliseconds, the converter streams high-resolution voltage and current waveforms to the NPU, which runs a lightweight convolutional network trained on more than 120 million real-world load signatures. The algorithm not only distinguishes resistive, inductive, capacitive, and non-linear loads but also flags anomalies such as neutral loss, arc faults, or impending contactor failure up to 14 days before they manifest as outages. In pilot deployments across 8,000 households in Austria and 200 commercial panels in Singapore, predictive alerts cut unplanned downtime by 38 % and reduced site visits for diagnostics by nearly half.

Bidirectional energy flow is natively supported, enabling precise net-metering for rooftop PV, battery storage, and vehicle-to-home setups. Utilities can choose between four open communication stacks—Wi-SUN FAN, NB-IoT, LoRaWAN, and Modbus-TLS—each with end-to-end AES-256 encryption and certificate-based mutual authentication. A zero-touch onboarding protocol allows meters to join the network out-of-the-box while still letting operators enforce role-based access policies from a central dashboard.

Environmental robustness meets industrial-grade standards. The meter operates flawlessly from –40 °C to +85 °C, withstands 6 kV surge pulses, and carries an IP51 rating without requiring external sealing kits. Inside, a solid-state shunt and film capacitors replace traditional Transformers and electrolytics, eliminating magnetic hysteresis and electrolyte aging. Accelerated-life testing predicts a mean time between failures exceeding 25 years, backed by a 10-year factory warranty.

Equally important is sustainability. GridLogic sources recycled aluminum for the DIN-rail clamp and halogen-free thermoplastics for the housing. A cradle-to-gate life-cycle assessment conducted by TÜV Rheinland shows 31 % lower carbon equivalent emissions compared with the nearest competitor, largely due to an energy-efficient manufacturing line powered by 100 % renewable electricity.

Pricing starts at under fifty euros in volume, including calibration certificates traceable to NIST and a decade of over-the-air firmware updates. Early adopters include Stadtwerke München, which will roll out 100,000 units as part of a citywide smart-meter refresh, and a pan-European retail chain seeking sub-metering granularity to meet the EU Energy Efficiency Directive’s requirement for real-time tenant billing.

“For decades, single-phase DIN-rail meters were viewed as commodity hardware,” said Dr. Elena Rossi, GridLogic’s Chief Technology Officer, at the product launch in Zurich. “OnePulse turns that notion on its head by embedding intelligence that learns, adapts, and communicates—transforming every panel into a data-rich node of the evolving energy internet.”

GridLogic will showcase live demonstrations of OnePulse at European Utility Week in Vienna this November, where engineers will stream predictive-analytics dashboards fed by meters installed across three continents. Registration for technical workshops is already oversubscribed, underscoring the industry’s appetite for meters that are not just accurate, but prescient.
