HED works on domotics, network, security, audio-video and energy projects — with commercial as our core focus, alongside residential and industrial — from study to commissioning.
Frequently asked questions
Clear answers before the first meeting.
This library will grow with real projects and questions actually asked by your clients.
Yes. HED provides study, design, costing, installation, programming, commissioning and follow-up after handover.
Yes, whenever the project allows it. Phasing, safety, working hours and continuity of activity are built in from the preparation stage.
Our typical positioning mainly covers installations ranging from around €20,000 to more than €500,000, depending on the nature and complexity of the project.
From Lyon, HED works across all of France (around 80% of projects) and in Europe (20%).
You have a main point of contact who centralizes information, decisions, coordination and follow-up.
Yes, the KNX bus is our reference standard: lighting, blinds, heating and life scenarios, with an open choice of manufacturers (Legrand, Hager, Jung, Gira, Schneider Electric and others).
No. We mainly work with Ubiquiti UniFi, Cisco and Ruckus depending on the need, with no brand exclusivity — the same approach applies to audio-video, any brand depending on budget.
Yes, it’s our field of choice: building management systems, access control, security and energy monitoring for offices, retail and reception areas.
Yes, those are our two other fields: bespoke installations for homes, and technical supervision/security for industrial sites.
Yes: structured cabling, professional WiFi, segmentation and supervision are part of our core services.
Yes, these installations are part of HED’s technical scope, integrated into the same scenarios as the rest of the smart-home system.
Yes. Beyond standard automations, we develop custom scenarios and, if the project calls for it, dedicated software tools.
Yes, HED can include the creation, adaptation and safety upgrade of electrical installations within project coordination.
Both ecology and economy: our energy installations aim for a better-managed footprint and measurable savings, visible over time.
Yes, as part of overall energy management: photovoltaic self-consumption, EV charging stations and load shedding are all part of our energy offering.
It’s one of the areas we’re developing: a clear view of what’s being consumed and saved, category by category.
You can fill in the detailed form on the site, attach the information you have, and we’ll get back to you to assess your needs.
Address, building type, surface area, planned systems, budget, schedule, site occupancy, plans, photos and specifications if available.
A serious project first requires understanding the need. HED will get back to you to clarify the scope before finalizing pricing.
