EV Charging & Metering
Classical meters become cloud-enabled,
Eichrecht-compliant EV chargers.
Replacing every existing energy meter to support EV charging is expensive and disruptive. XFactr.AI takes a different approach building a secure communication card that attaches to classical meters, adding cloud connectivity and full Eichrecht compliance without touching the base meter hardware or halting production.
Eichrecht Standard Compliance
Every charge session is cryptographically signed and tamper-proof kWh delivered is legally auditable, independently verifiable by the EV driver, and compliant with German calibration law for billing transparency.
Secure Bootloader & Chain of Trust
Digital signatures verify firmware authenticity at every boot stage from hardware to application layer. A layered trust model ensures each component verifies the next, eliminating the possibility of unauthorized firmware running on the meter.
ECDSA Signatures via Secure Element
Meter readings are signed using ECDSA keys stored in a hardware secure element keys never leave the device, protecting measurement integrity and authenticity in transit from meter to cloud billing system.
Anti-Rollback Protection
Firmware downgrade attacks are blocked at the bootloader level each firmware version is monotonically versioned, preventing an attacker from reverting a meter to a known-vulnerable state.

Security Architecture
Security baked in at every layer
from silicon to cloud.
A chain of trust that starts at the hardware secure element and extends all the way to the cloud billing system. Every firmware update is cryptographically signed. Every meter reading carries an ECDSA signature verifiable by any independent party. Every boot cycle is verified before application code runs.
The same security architecture protects both the EV charging path and the smart home energy management control plane — because the consequences of a tampered meter or a hijacked home automation command are equally serious.

Smart Home Energy Management
Automated home energy control with IP
access to every protocol.
Home automation systems built using proprietary protocols (including C-Bus and Combus) deliver fully automated control of lighting, HVAC, and electrical systems. XFactr.AI adds an IP/Ethernet overlay that provides unified, standards-based access to these proprietary protocols without replacing the existing installation or rewiring the home.
IP/Ethernet Access to Proprietary Protocols
C-Bus, Combus, and other proprietary home automation protocols accessed via a standard IP/Ethernet overlay enabling modern dashboards, APIs, and remote monitoring without dismantling the installed system.
Automated Lighting & Electrical System Control
Schedules, occupancy triggers, energy thresholds, and scenes drive automatic lighting and load control reducing energy waste during unoccupied periods and eliminating manual switching across the home.
Real-Time Data & Performance Reporting
Live energy consumption data, device status, and historical trends accessible via web dashboard and API giving building owners and facilities teams full visibility into energy performance and reliability.
Reduced Maintenance & Business Continuity
IP-based remote diagnostics and access mean fewer site visits for routine maintenance. Real-time fault detection surfaces issues before they become outages ensuring continuous operation and cost-effective energy management.
