Vienna is the only city in Austria where we have a delivered project — and the type of that project says more about the market than any industrial list. Not a big assembly at a carmaker. Not a data hall in Donaustadt. **A private villa** in the 19th district with complete Loxone integration, KNX bus, DALI-2 lighting, Frigate VMS, and a local Ollama LLM. That's the reference point we speak from about Vienna — the high-end smart-home segment, where the client doesn't want cloud, doesn't want subscriptions, doesn't want dependence on a foreign vendor backoffice.
Loxone smart-mansion — our Vienna entry point
`smart-mansion-loxone` (2025) was proof for us that the Austrian high-end residential market can tell an integrator who "installs the product" apart from an integrator who builds the whole ecosystem. In this project the KNX bus served as a stable hardware layer (shutters, doors, windows, underfloor heating), the Loxone Miniserver Gen 2 as the orchestration brain, DALI-2 as tunable-white lighting via Helvar drivers, Frigate with local Coral TPU accelerators for object detection on outdoor cameras, and Ollama with a privately hosted LLM (Qwen 2.5 14B on a Ryzen 9 + RTX 4090 rig in the utility room) for voice control and a personalised assistant for the owner.
What makes this project interesting isn't the number of integrated systems — it's their **layering**. KNX stays reliable even when the internet drops. The Loxone Miniserver keeps running even when KNX has a local bus error. Frigate has its own NVR loop independent of cloud services. Ollama never sends voice data anywhere outside the house. For an owner asking "what happens when there's lightning outside and the internet's gone for 2 days" — the answer is "nothing happens, the house runs the same as if you were online."
Regulatory framework — Wiener Bauordnung + OIB
In Vienna, building decisions are made under Wiener Bauordnung (WBO) + OIB-Richtlinien (1 mechanical strength, 2 fire safety, 3 hygiene, 4 safety in use, 5 noise protection, 6 energy efficiency). For Loxone-type projects, OIB 4 (fire safety — KNX systems on evacuation routes) and OIB 6 (energy efficiency — DALI-2 tunable white must contribute to the EPB calculation, not just sit alongside it) are particularly relevant.
For electrical installations ÖVE/ÖNORM E 8001 + E 8002 (special environments — sauna rooms, pools, technical cleanrooms in private homes are real, especially in Hietzing and Döbling). For inspections ETV 2020 — periodic electrical-installation inspections every 5 years for residential, annually for commercial above 1,000 m².
Cross-border vector — the Vienna triangle
Vienna sits in one of Europe's strongest cross-border nodes. 60 km to Bratislava, 70 km to the Hungarian border, 250 km to the Czech border. For an integrator who keeps A1 documentation on standby, that means a "Vienna project" in practice often means the Danube area in Bratislava, the supplier orbit around Audi Hungaria Győr, or the Magna Liesing logistics hub. For our operations from Prešov it's a 6-hour drive on D1/A4 — comparable to Bratislava plus one hour through Schwechat.
In practice we maintain a weekly contact rhythm with Vienna clients. For on-site visits and spec meetings, we fly via BTS (50 minutes from Košice) plus 60 km by car. For longer deployments (Loxone hardware install + commissioning standardly takes 3–4 weeks) we lodge within reach of Schwechat or directly in Wieden.
Posted Workers — e-ZKO routine
For work in Vienna we need e-ZKO registration via the BMAW portal 7 days in advance, A1 from the Slovak Social Insurance Agency, and documentation showing compliance with the Kollektivvertrag for electrotechnical work (KV Elektro-, Audio-, Video- und Alarmanlagen — current Facharbeiter rate around €21 gross per hour). Cross-border VAT goes via reverse charge under § 19 UStG 1994 — invoice with the client's Austrian VAT number and the standard "Übergang der Steuerschuld" note.
Which pillars fit best
For Vienna unambiguously **Smart Buildings + Software/AI**, exactly in the spirit of the Loxone project. KNX/Loxone/DALI-2 integration, Frigate VMS with local AI supervision, Ollama-based private LLM assistant. Our tech stack fits precisely here: KNX bus as the foundation, Loxone as orchestration, local AI as the differentiator against integrators still shipping data to AWS/Azure clouds.
For the data centre segment (NTT Wien, Equinix VI1, Interxion VIE1) **Data Centres + Software/AI** with focus on DCIM (EcoStruxure IT), cooling design (rear-door HX for racks above 25 kW), and AI cluster integration for tech firms' R&D branches. We haven't delivered this in Vienna yet, but we've done the same type of work in Cluj-Napoca (`ai-cluster-research-lab`).
For Siemens Mobility Floridsdorf, OMV Vienna, Frequentis and similar enterprise clients — **Industry + Automation** via Sondermaschinenbau and robotic-cell integration. Here we're looking for the first client and we're in the pre-engagement phase.
Conclusion — what's expected of us in Vienna
In Vienna the client usually finds us by having heard about the Loxone project through acquaintances or via specialised smart-home forums. The first question that lands is usually "can you do it without cloud?" — and the answer is yes. That's our differentiator for the Austrian high-end residential market. For larger commercial projects (data centres, automotive supplier) we're at the early-stage relationship-building phase in Vienna — the reference so far is residential, but the transferable competencies are ready.
