Harmony Hub WebSocket Nodes for Node-RED
JSON →A Node-RED contribution package (v2.2.6) that provides three nodes (HWS command, HWS activity, HWS observe) to control Logitech Harmony Hub devices over WebSocket. Released under the MIT license, it works around the firmware 4.15.206 breaking change. Alternatives include node-red-contrib-harmony (HTTP-based) and node-red-contrib-harmony-websocket-sc, but this package focuses on WebSocket communication with automatic IP discovery.
