Z-Wave JS vs Z-Wave JS UI
A side-by-side editorial comparison of Z-Wave JS and Z-Wave JS UI — release velocity, themes, recent moves, and the top alternatives to consider.

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 tracks library updates steadily while adding Window Covering MQTT discovery
Z-Wave JS UI is on a regular maintenance cadence, tracking zwave-js library releases from 15.24 to 15.29 across six releases in roughly three months. The 11.23.0 release added a network speed column and expanded Home Assistant MQTT autodiscovery to Window Covering CC (blind/shade) devices. Dependency updates for morgan and multer accompany most releases.

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 tracks library updates steadily while adding Window Covering MQTT discovery
◆ Current state
Z-Wave JS UI is on a regular maintenance cadence, tracking zwave-js library releases from 15.24 to 15.29 across six releases in roughly three months. The 11.23.0 release added a network speed column and expanded Home Assistant MQTT autodiscovery to Window Covering CC (blind/shade) devices. Dependency updates for morgan and multer accompany most releases.
◆ Where it's heading
The core product is stable; visible change velocity is driven by the upstream zwave-js library rather than UI-level feature work. The agentic issue classification and documentation Q&A bot (11.22.1, using local embeddings computed without GitHub Models) shows the team beginning to automate contributor support—a sign of a healthy open-source project managing issue volume rather than a product pivot.
◆ Prediction
Feature additions will continue to track zwave-js library capabilities. Expect Home Assistant autodiscovery support for additional command classes as zwave-js 15.x expands coverage. The credential management UI shipped in 11.22.0 may see configuration improvements as users report friction.
