Plenom A/S is a Danish hardware-software house that has specialized since 2003 in “Busylight” presence management for open-plan offices and remote teams. The company’s kuando ecosystem turns a simple USB or PoE lamp into a real-time signal that shows whether a colleague is available, busy on a Teams call, in Do-Not-Disturb focus time or away from the desk. kuando In-A-Call is the lightweight client that reads the presence state of Microsoft Teams, Skype for Business, Cisco Jabber, Zoom, RingCentral and other UC platforms and instantly changes the Busylight color to red, green, yellow or purple, eliminating the need for manual status updates and reducing interruptions during video conferences. kuandoHUB is the companion configuration suite that lets IT administrators and power-users map custom colors, flash patterns and audio alerts to any presence event, set keyboard shortcuts, prioritize which platform takes precedence when several are active, synchronize with Outlook calendar categories, and push firmware or color-scheme updates to hundreds of lamps at once. Together the two applications create a visual traffic-light system that scales from a single home office to multi-floor contact centers, improving concentration time, lowering noise levels and giving managers an at-a-glance occupancy overview. Both programs run quietly in the Windows system tray, support Citrix/VDI deployments and comply with enterprise proxy policies. Plenom’s kuando software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the newest release and allowing several related titles to be deployed in one batch operation.
