May 2026 monthly summary focusing on delivering features and stabilizing core bindings across openhab-addons and openhab-webui. Business value delivered through interoperability improvements for Dahua door intercoms, reliability enhancements in EnOcean outbound messaging, and expanded UI automation capabilities.

April 2026 focused on delivering secure, interoperable Dahua door integrations and expanding device control capabilities in openhab-addons. Key deliverables include: 1) Dahua door network discovery and HTTPS-enabled communication: auto-discovery over DHIP UDP multicast and HTTPS support for DahuaDoor binding, reducing manual configuration and improving security. 2) Unified SIP and WebRTC intercom integration for Dahua door systems: end-to-end intercom flow with SIP baseline and call-state channels, WebRTC streaming via go2rtc, SDP parsing, backchannel relay, and lifecycle wiring, enabling reliable, standards-based door intercom operations. 3) Advanced control for the FSB14 blind system: a state-machine-based control with multiple configuration modes, automatic calibration, and backward compatibility support. 4) Security, reliability, and quality improvements across the media stack: hardened WebRTC proxy/go2rtc handling, addition of SIP SDP parser tests, and strict RTP header validation to reduce edge-case failures. These efforts deliver tangible business value: faster onboarding for Dahua door devices, secure communications, robust intercom and media handling, and expanded automation support for blinds.

March 2026 (openhab/openhab-addons) focused on broadening hardware interoperability and reinforcing EnOcean bindings. Delivered four features: RS485 Sender ID Support with per-device Base ID addressing; DahuaDoor Binding Integration enabling doorbell notifications, camera snapshots, and remote door control; EnOcean Datagram Injector for Eltako Bus Actuators providing send-only command injection and sensor emulation (motion detection and contact switch profiles); and EnOcean Binding State Machine Infrastructure to standardize device state management and transitions. These changes improve device management, testing capabilities, and future extensibility, delivering tangible business value by enabling broader hardware compatibility, faster integration cycles, and more robust automation scenarios. Demonstrated skills: embedded protocol handling, binding architecture, state machine design, and disciplined commit hygiene.
