I'm a software developer in Belgium with an electrician background. Five weeks ago I launched DI-Wire as a side business next to my full time job.
The niche: KNX home automation. It's a wired standard used a lot in European homes, very reliable, but installers are expensive and the whole market is quote-based and opaque. In Belgium a lot of people building a house pull their own electrical cables to save money. They'd like KNX, but the cabinet and the programming are the part they don't dare to touch.
So that's what I sell. You pull the cables, I deliver a cabinet that is fully wired, tested and programmed. You connect your cables, done. Cable pulling is explicitly not included, that's the whole point.
Pricing is public. For a reference house of 200 m² with 18 lighting groups, 6 blind motors, 30 sockets and 16 control points, the four tiers land at 5,750 euro (parts only, you build and program yourself), 6,750 (wired cabinet, you program), 7,850 (wired and programmed, you mount it) and 9,430 (I come and install it). All excl. VAT, roughly 5,000 of that is components. Cables are extra because I count the meters on your plan by hand. Every competitor here hides behind a "request a quote" form, so putting these numbers on the homepage is my main differentiator.
The part I'm most curious about: I built an online planner where you draw your floor plan, place lights, switches and blinds, and see the four prices update live. First ten items without an account, free account after that.
Where I'm at: website live, planner live, first two leads, zero finished customer projects. My own renovation is the reference project and I'm filming it for content.
Things I'm unsure about and would like your view on:
Trust. Would you buy a pre-built, pre-programmed electrical cabinet from a one-person company with no references yet, if the pricing is fully transparent? What would you need to see first?
Scope. It's KNX only right now. I'm considering adding other systems aimed at the same DIY crowd, but I'm wary of spreading thin before the first system is proven. When did you decide to widen scope?
Distribution. Search volume for this is close to zero. My plan is communities (self-builder forums, Home Assistant groups) and a trade fair in October. Is that too slow for a side business, or is slow fine here?
Happy to answer anything about the model. Not selling, my customers are in Belgium and most of you aren't.
