January 2026 (2026-01) performance summary for EVerest/everest-core. Delivered a robust Internal Over-Voltage Monitoring System within EVSEManager to enhance safety by detecting over-voltage conditions and triggering appropriate faults. The monitor uses configurable error and emergency limits to ensure timely responses to potential hazards, aligning with safety and reliability goals for EVSE operation. This work is anchored by commit d434b586b85e59ce279814d773fa41eaee15e132 (#1595).

December 2025: Delivered two core features in EVerest/everest-core that enhance system simulation fidelity, observability, and reliability. The Over-Voltage Monitoring Module with MQTT Publishing enables real-time publishing of measurement values and external control for improved testing and system validation. The Modbus stack gained a dedicated Timeout error in StatusCodeEnum, with enhanced timeout logging and adjusted result status to distinguish application/functional vs. communication errors, improving fault diagnosis and maintainability. These changes reduce debugging time, improve testing workflows, and strengthen the robustness of the Modbus integration. Technologies demonstrated include MQTT publishing, SIL module support, Modbus error handling, error enumeration refinement, and logging.

November 2025 (EVerest/everest-core): Focused on safety-critical EVSE enhancements and data integrity. Delivered two features and fixed key data handling issues, with improvements in testing readiness that enable safer operations and easier validation of future changes. Key commits address data serialization/deserialization fixes and safety controls.

October 2025 monthly performance summary for EVerest/everest-core focused on delivering a robust power module driver and enhancing system observability. Delivered the Winline PowerSupply CAN Bus Driver with discovery and monitoring, enabling reliable control of Winline power modules over CAN with both fixed address and group discovery modes. The change set includes enhanced error handling and status monitoring, improving fault visibility and resilience. Integrated into Everest core, enabling scalable power module management and reducing manual testing overhead.

2025-08 monthly summary for EVerest/everest-core focusing on reliability, fault detection, network communication, and observability. Key deliverables include critical fault handling enhancements for EvseManager with MREC22 resistance faults and MREC11 cable check faults, a dedicated network interface configuration for LemDCBM400600 communication, and improved log readability by displaying voltage and current with two decimals. These changes enhance safety during charging, improve diagnostics and incident response, and provide more controlled and observable system behavior across the core module.

In July 2025, delivered a foundational improvement to the gpio library enabling external installation and usage outside everest-core. By adding CMake installation rules for the gpio target and header files, external projects can link and include gpio with a standard install layout, reducing integration friction and improving modular reuse across teams. This aligns with modernization goals and prepares the gpio library for broader adoption and downstream product builds. The work is captured in commit b922e854016cfa6cba0d70746ab4dd3bfe9b9be3 ("Make sure that gpio lib can be used outside everest-core (#1253)"), reflecting a clear path to external usability and maintainability.

June 2025 performance summary for EVerest/everest-core: Delivered reliability and data availability improvements for LEM power meters, including a configurable HTTP connection timeout, correct Time Zone and DST handling when NTP is enabled, and OCMF field caching exposed in stop transaction responses. These changes reduce data gaps during connectivity issues and improve time-accurate data delivery. All changes consolidated in the June work for commit 8a8fb7ddf4018ad82f5b5a4b1ff9db305d7b1d89 (#1215).

March 2025 monthly summary focusing on reliable transaction handling and runtime observability. Delivered critical bug fixes across Everest core and framework to reduce production incidents and improve developer experience. Key outcomes include robust error recovery for LEM DCBM transactions and resilient logging path resolution that works across installation prefixes.

January 2025 Monthly Summary: Delivered robustness enhancements for Powermeter/EvseManager with a new fail-on-error configuration, comprehensive error handling updates, and enhanced run/start-recovery documentation. Documentation includes a Mermaid diagram illustrating the transaction start/stop flow during powermeter interruptions. These changes improve safety, reliability, and operator clarity in EVSE control.
