Z-Wave JS vs Z-Wave JS UI: at a glance
What is Z-Wave JS?
Z-Wave JS overhauls its RCP firmware driver in a nine-PR push toward production readiness.
Z-Wave JS v15.x is in active maintenance and incremental feature development, shipping roughly every 1–3 weeks. The library is the backbone of Z-Wave support in Home Assistant via the Z-Wave JS add-on, and recent releases have split attention between hardware driver improvements (RCP support, proprietary controller commands) and protocol reliability (command deduplication, interview sequencing, S2 encapsulation fixes). The v15.28.0 RCP driver overhaul is the most concentrated single-version effort in this range.
What is Z-Wave JS UI?
Z-Wave JS UI ships credential management UI and trusted API separation, moving toward multi-user deployment scenarios.
Z-Wave JS UI 11.22–11.24 marks a shift beyond single-user personal use: credential management UI, trusted API on a separate network and port, and Window Covering CC Home Assistant entity discovery all landed in quick succession. The project also upgraded its community support bot from GitHub Models to local embeddings with agentic triage workflows. Security hardening has been consistent — path traversal fixes, TLS key permissions, mandatory strong session secrets — throughout this release window.
Z-Wave JS vs Z-Wave JS UI: editorial side-by-side
Z-Wave JS
6.3DEVOPS
Z-Wave JS overhauls its RCP firmware driver in a nine-PR push toward production readiness.
◆ Current state
Z-Wave JS v15.x is in active maintenance and incremental feature development, shipping roughly every 1–3 weeks. The library is the backbone of Z-Wave support in Home Assistant via the Z-Wave JS add-on, and recent releases have split attention between hardware driver improvements (RCP support, proprietary controller commands) and protocol reliability (command deduplication, interview sequencing, S2 encapsulation fixes). The v15.28.0 RCP driver overhaul is the most concentrated single-version effort in this range.
◆ Where it's heading
The dominant hardware trend in Z-Wave JS is Radio Co-Processor (RCP) architecture support — the new topology used by Nabu Casa Yellow and similar embedded smart home hubs, where the radio is a co-processor with separately updatable firmware rather than a monolithic USB stick. The library is making a clear investment in this path. Alongside that, interview reliability improvements (pausing during inclusion, deduplication of queued commands) signal a focus on reducing setup friction for multi-device deployments.
◆ Prediction
RCP support will graduate from experimental to stable in a coming release as the driver matures. The `lastAwake` persistence added in v15.29.0 is the kind of foundational telemetry that enables smarter polling and sleep-cycle optimization — expect follow-on features that use it.
Z-Wave JS UI
5.0DEVOPS
Z-Wave JS UI ships credential management UI and trusted API separation, moving toward multi-user deployment scenarios.
◆ Current state
Z-Wave JS UI 11.22–11.24 marks a shift beyond single-user personal use: credential management UI, trusted API on a separate network and port, and Window Covering CC Home Assistant entity discovery all landed in quick succession. The project also upgraded its community support bot from GitHub Models to local embeddings with agentic triage workflows. Security hardening has been consistent — path traversal fixes, TLS key permissions, mandatory strong session secrets — throughout this release window.
◆ Where it's heading
The product is expanding from a local personal-server tool to something usable in shared-network and multi-user home deployments. Home Assistant integration deepens with each release (Window Covering CC, multicast groups). Node.js v24 adoption and the explicit OIDC publishing mention signal that auth-layer expansion — possibly OIDC/SSO — is coming.
◆ Prediction
Credential management will likely extend to OIDC or role-based access given the Node.js v24 OIDC infrastructure already in place. Home Assistant entity coverage will continue to grow incrementally with each zwave-js library bump.
