Device Overview
Smappee Infinity is a modular energy-management and metering system rather than a single clamp monitor. It is designed for installations that need to measure energy flows from the main connection down to circuits, loads, solar PV, storage, EV charging, and other assets.
Core Characteristics
The system is built from Smappee modules such as the Power Box, CT Hub, Solid Core 3-Phase CT, communication gateways, and optional input/output modules. The Power Box measures line voltage and works with current sensors to calculate power, energy, and power-quality data. CT Hubs can connect multiple CTs or Rogowski coils, while the broader Infinity architecture can expand across many measured circuits.
Installation and Fit
Infinity is an installer-led product. Smappee's installation manual says the Power Box, CT Hub, Solid Core 3-Phase CT, current transformers, and Rogowski coils are usually installed inside the distribution board under protective cover, and that only certified electricians or equivalent personnel should install the system.
Compatibility and Data Access
Smappee positions Infinity as a cloud-connected energy-management platform with app and dashboard access. The Smappee Power Box also supports Modbus RTU register readout over its B-Port, which gives projects a local data path for supported measurements. Smappee documentation also references MQTT, EEBUS, Home Assistant, and OpenHAB pairing or integration contexts.
Best-Fit Scenarios
Infinity is strongest for homes, buildings, and small commercial sites that need more than one simple whole-home number. It is especially relevant where solar, storage, EV charging, HVAC, major appliances, or multiple distribution boards need to be monitored or coordinated.
Limits and Caveats
This record treats Smappee Infinity as an energy-meter / energy-management metering system, not as an inverter, battery, EV charger, or gateway-only product. The maximum-current field reflects the highest published compatible Rogowski coil range, so real project design must match the selected CT or Rogowski sensor to the conductor and application. A formal whole-system revenue-grade accuracy class was not verified; Smappee does publish 0.2% accuracy-class context for its Solid Core 3-Phase CT.
