CASAIO GmbH

What CASAIO GmbH does

CASAIO GmbH is a privately held German Smart Home specialist based in Veitshöchheim (near Würzburg), Bavaria, that designs, plans, programs, commissions, and maintains building automation systems based on the KNX open standard (IEC 14543). The company, led by CEO and founder Dr. Thomas Lübbeke, operates with a core team of eight specialists including KNX-certified system integrators, an electrical planner, a sales/customer management lead, and a Smart Home project manager. Its service range covers the full lifecycle — consulting, electrical planning, engineering, ETS programming, commissioning, multi-trade coordination, and ongoing maintenance — and extends from self-execute DIY support to high-end turnkey residential projects, with project values typically tied to homes exceeding €1M in construction sum.

The company's offering is built on a wired KNX bus backbone supplemented by DALI for professional lighting, KNX-RF for wireless extensions, and Matter/HomeKit/Google Home bridges for consumer-platform integration. Following a 2026 merger with Lumetix, CASAIO added Human Centric Lighting design using PI-LED technology (1,800K–16,000K color temperature range from KITEO). Beyond core professional services, CASAIO monetizes an online shop for Smart Home hardware, a KNX Masterclass online training program, 1:1 coaching, and the published book 'Dein Weg zum Smart Home'.

Revenue is generated through a hybrid model: fixed-fee package services and time-and-materials engagements (billed in 15-minute increments) for B2C/B2B project work, hardware sales via the online shop, subscription/annual pricing for the KNX Masterclass, one-time fees for the book, and recurring maintenance contracts. The customer base is concentrated in private residential homeowners (Bauherren) and architects, with a secondary DIY segment served through education channels. The company is active across the DACH region via project partners, has completed over 100 projects, and holds the KNX Award 2018.

Scale indicators3 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Gira: German premium manufacturer of KNX-compatible switches, sensors, and home servers. CASAIO is a certified Gira Systemintegrator (a partner relationship), but Gira also competes at scale through its broad dealer network and own-brand smart home solutions for the same premium residential projects.
• Schneider Electric: Global energy management and automation giant with KNX-based residential solutions under its Wiser brand. Comparable as a broad incumbent with KNX-based offerings competing for residential building automation projects, but at global scale and across many adjacencies.
• Bosch Smart Home: Broad consumer smart home brand offering its own ecosystem of DIY-friendly controllers, sensors, and appliances. Comparable as a residential smart home competitor in DACH, but with a more consumer-focused, less integrator-heavy go-to-market than CASAIO's premium KNX specialist model.
• JUNG: German premium manufacturer of KNX building automation hardware (switches, sensors, KNX modules, LS 990 design line). Comparable to CASAIO as a KNX ecosystem participant competing for high-end residential design projects, but operating at manufacturer scale with a national installer network.
• Hager: European manufacturer of KNX building automation and electrical installation products with a strong German dealer network. Comparable as a KNX ecosystem participant competing for residential building automation projects, but at manufacturer scale with broader product lines than CASAIO.
• ABB Busch-Jaeger: Global industrial automation giant with a major KNX presence via its Busch-Jaeger subsidiary (KNX actuators, sensors, control panels). Comparable as a broad incumbent competing for premium residential and commercial building automation projects, with vastly greater resources and global reach.

Emerging players

• digitalSTROM: German smart home platform using its own wired (and hybrid) technology as an alternative to KNX. Comparable as a DACH-based residential smart home specialist targeting integration projects, but with a smaller, niche technology footprint than CASAIO's KNX base.
• mediola: German smart home integration platform providing gateways and software to connect diverse smart home protocols (KNX, Zigbee, Z-Wave, Matter). Comparable as a DACH smart home integration specialist, but focused on enabling-tooling rather than turnkey project delivery like CASAIO.

Direct peers

• myGEKKO: Smart home controller manufacturer (Italian/German roots) with focus on KNX integration for premium residential and commercial projects. Direct peer to CASAIO in the integrator-led premium smart home segment, targeting similar customers with overlapping technology approaches.
• Loxone: Austrian smart home platform vendor offering its own proprietary ecosystem (Miniserver, Tree, Air) with a partner installer network targeting premium residential projects in DACH. Loxone is CASAIO's most direct competitor because it competes for the same premium homeowner and architect customers, but with a closed ecosystem rather than KNX.
