Career history
In the news
- What’s your favourite way to navigate a building automation app: lists, floor plans, or animated synoptics? My preference depends on what I’m doing: → Rooms and category lists for quick actions. → A floor plan for an overview of the building. → Animated synoptics for understanding building systems, especially HVAC and energy. These are the three views I use in HyperVisu. Each has its place. Which do you use most in your projects—and why? #KNX #BuildingAutomation #HyperVisu
- Building Automation Integrators? STOP for a moment, and watch this ! More ways to connect your projects. More freedom to shape the experience you deliver. One server, connected systems Bring together KNX, Modbus TCP, MQTT, BACnet/IP, HTTP and TCP/UDP, alongside integrations with Home Assistant, Sonos, Node-RED and Grafana, all running on the same server with a fully visual automation logic engine. A new app, tailored to every project Create custom dashboards and interactive floor plans. Build views with animated symbols and
- Lights off. One screen still on. I can't keep this one to myself until the launch... The new HyperVisu arrives 10 September: new app, new configuration, same screen on every device in the building. I think you're going to love it as much as me! #BuildingAutomation #SmartBuildings #KNX #HomeAutomation
- Ajax alarm panels already know when someone's home. Most KNX installations don't. For years the only bridge between an Ajax panel and a KNX installation was a couple of dry contacts. Four anonymous on/off bits. No zones, no arming state, one direction. We built the AJAX-KNX gateway to close that gap properly. Every zone and area, the arming state, and 6 status types — all exposed as native KNX group objects, both directions. Commissioning is one ETS application. A few things it unlocks on site: → Arming becomes a scene trigger —
- Your client just installed a Sigenergy inverter. Their solar data? Locked inside an app — invisible to the KNX system running their building. Not anymore. The ELAUSYS INV-KNX gateway now speaks Sigenergy. One DIN-rail device reads the inverter over Modbus TCP and puts live PV production, battery storage and grid exchange straight onto the KNX bus — plug & play ! That means self-consumption, peak-shaving and dynamic-tariff logic run entirely on KNX. And Sigenergy is just the latest. One identical KNX application now covers: ☀️
