What Electrical Engineering does

E-Technik GmbH & Co. KG is a family-owned electrical installation company (Elektro-Meisterbetrieb) headquartered in Ahrensbök, Schleswig-Holstein, Germany, founded in 1978 by Heiko Wäcken and currently managed by Stefan Wäcken as Geschäftsführer. The legal entity is a German GmbH & Co. KG with Elektro-Wäcken-Verwaltungs GmbH as personally liable general partner, and the ownership remains entirely within the Wäcken family with no external investors. The company serves private residential customers, commercial businesses, public institutions, and healthcare facilities across eastern Schleswig-Holstein — including Ahrensbök, Bad Segeberg, Eutin, Malente, Lübeck, Kiel, Neustadt, and surrounding coastal towns.

The service portfolio spans seven core lines: electrical installations (new builds and renovations), Smart Home installations built around the RADEMACHER HomePilot central unit and the DuoFern bidirectional radio system (with add-on modules for lighting, heating, roller shutters, motion detection, and cameras), data/network technology, security and safety technology (smoke detectors, alarm systems, video surveillance, access control), lighting design, photovoltaic (PV) system installation, and nurse call systems for hospitals and care facilities. E-Technik is a certified RADEMACHER 3-star partner and installs Hekatron smoke warning components. The HomePilot platform integrates with Amazon Alexa, Google Assistant, and Philips Hue (via Hue Bridge, enabled since a 2019 software update).

Revenue is generated almost entirely through professional services — installation, configuration, and maintenance — billed via a publicly available price list (Unsere Preispolitik). The go-to-market is sales-led and direct: the company acquires customers through local presence and direct on-site engagement within its service area, with no disclosed digital marketing channels beyond the company website. No revenue figures, headcount numbers, or financial disclosures are publicly available.

Broad incumbents

• SPIE GmbH: European multi-technical building and energy services provider with a substantial German electrical installation footprint spanning commercial, industrial, and public-sector clients. Comparable to E-Technik in the commercial and public-institution electrical work segment, but at a much larger scale.
• Gira Giersiepen GmbH & Co. KG: German manufacturer of smart home systems, KNX-based building automation, and electrical installation devices marketed through electrical contractors. Comparable as another upstream platform supplier competing with RADEMACHER for E-Technik's specification and partner-program decisions.
• Hager Group: German-French manufacturer of electrical installation systems, smart home solutions, and energy management products distributed via electrical contractors. Comparable as a parallel platform vendor to RADEMACHER for Smart Home and electrical installation specifications in the same installer channel.
• ELOMECH Gruppe: German multi-trade electrical services group covering electrical installation, automation, security, and network technology for industrial, commercial, and residential customers. Directly comparable in service mix (Elektroinstallation, Sicherheit, Datentechnik) but operates across multiple German regions with substantially larger headcount.
• Schneider Electric (DACH): Global energy management and automation company with a strong German presence offering electrical installation, smart home, and energy management solutions through installer channels. Comparable as an upstream platform vendor with deeper smart-home/energy management tooling than RADEMACHER.
• Busch-Jaeger (ABB): German manufacturer of electrical installation and smart home systems (part of ABB), sold exclusively through electrical installers like E-Technik. Comparable because Busch-Jaeger competes at the platform level for Smart Home specification decisions, influencing which installer partner gets the project.
• GA-tec Gebäude- und Anlagentechnik GmbH: Germany-based multi-location building services and technical facility management company offering electrical installation, security, and building technology services. Comparable to E-Technik across core electrical installation work, but operating at a much larger national scale with a broader service portfolio.

Direct peers

• Loxone Electronics GmbH: Austria-headquartered smart home specialist that sells through a certified installer partner network (Loxone Partner), directly mirroring E-Technik's RADEMACHER 3-star partner model. Comparable because Loxone competes for the same smart-home-installer mindshare and end-customer wallet in the DACH region.

Emerging players

• 1Komma5° GmbH: Hamburg-based PV, heat pump, and EV charging installer that is rapidly building a national rollup of regional electrical contractor brands. Comparable because it directly targets the same end customers (PV + e-mobility retrofits) that E-Technik serves, and competes for installer capacity in the same labor pool.
• Enpal GmbH: Berlin-based PV/solar leasing company that bundles solar systems, battery storage, heat pumps, and EV charging into a single subscription, scaling installer capacity through partner networks. Comparable to E-Technik on the PV installation side, but operates at a substantially larger scale with a fintech-style leasing model.
