Career history
In the news
- When diagnosing a problem in a building's automation system, having the right tools makes all the difference. HyperVisu already provides historical KNX bus monitoring, device activity logs and measurement history to help retrace what happened on an installation. But what if we could simply ask: “Why did the heating switch on last night?” An AI assistant can help investigate the available data and identify a likely cause. The integrator can then verify the explanation against the installation. That’s what our new MCP connector
- I’m pleased to introduce Apple Home and Siri integration for HyperVisu! You can now bring supported devices from your HyperVisu installation into Apple Home and control them with your voice. Lighting, blinds and Climate part of the experience you already use. “Hey Siri, turn on the kitchen lights.” For integrators, it’s another way to make building automation feel natural for customers, while keeping HyperVisu at the heart of the installation. The HomeKit bridge is now available in beta, just press the update button and
- 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: ☀️
