 - hardware/infiniband.nix adds infiniband subnet manager support using an [opensm](https://github.com/linux-rdma/opensm) systemd-template service, instantiated on card guids. The module also adds kernel modules and cli tooling to help administrators debug and measure performance. Available as [hardware.infiniband.enable](#opt-hardware.infiniband.enable).
 
+- [zwave-js](https://github.com/zwave-js/zwave-js-server), a small server wrapper around Z-Wave JS to access it via a WebSocket. Available as [services.zwave-js](#opt-services.zwave-js.enable).
+
 - [Honk](https://humungus.tedunangst.com/r/honk), a complete ActivityPub server with minimal setup and support costs.
   Available as [services.honk](#opt-services.honk.enable).
