Sensor data, turned into decisions. And you own every part of it.
We build connected systems for public organisations and companies, then hand them back: code, data, architecture, all yours.

// the usual mess
A few years in.
Adopt IoT for a while and the estate ends up here. This is normal. It's also fixable.
Every vendor brought a portal.
Each supplier, its own login and export.
The history is hostage.
Years of readings you can't take with you.
No single view.
Four teams, four tools, one dataset.
Collected, not usable.
The readings arrive. Decisions don't.

Yours.
Where the code lives, who reaches the data, how you get it all back if we're gone. Decided on day one, in writing.
The data is yours.
Your storage, your keys, your retention.
The architecture is yours.
Documented decisions, in plain language.
Replaceable on purpose.
Run it yourself, or hand it to anyone else.
Deploy where you want.
On-prem, sovereign, EU, or hyperscaler.
Built for the regulation.
NIS2, DORA, CRA — in scope by design.
// 02 — servicesWhat we do.
What we do.
And what we don't.
No reselling, no licences. We build and run connected systems with your team, end to end.

NIS2 is in force. Sensor data is in scope.
Operational and sensor data sit squarely inside NIS2, and most IoT estates were never built for it. We design for it from the architecture stage, not patch it in afterwards.
- In force since January 2026
- Every kommun and region in scope
- Accountability reaches named individuals
// 04 — who we work with
Built for your estate.
Public bodies and the operators around them. Same fragmentation, same regulation, same answer: a system you own.

// 06 — a word from the founder
From my desk to yours.
Zero46 is a small IoT consulting practice based in Malmö. Here's the short version from the person running it.
founder · engineer · malmö
Eight years of shipping meter fleets, alarm systems, and data platforms shaped how Zero46 works. One senior architect, not an account team. The person you meet is the person who builds it, and stays on the project from first call to handover. You won't talk to a salesperson, and you won't be passed to whoever happens to be free.
If it needs to survive production, I'd like to hear about it.

// 07 — faq
First questions.
Short answers. Ask if yours isn't here.
We work in four named stages: Discover, Design, Build, Operate. Each has a clear output, a set price, and a named end. Most projects run 3 to 9 months end to end.
No. Our advice isn't tied to a vendor quota. If you're on AWS, Azure, or on-prem already, we work inside it.
Fixed price per stage, scoped on the first call. Each chunk has a set number before it starts, so no surprise invoices.
One senior architect, hands-on. You won't talk to a salesperson, and you won't be reassigned to whoever happens to be free mid-project. Behind it: eight years of production IoT, including smart-meter fleets at Waltero, alarm systems at Careium, and industrial data work via Axians and PRYM.io, now running a sensor platform for a Swedish municipality. The person on your first call is the person writing the code.
Based in Malmö, Sweden. We work across the EU and UK, on-site when it helps, remote when it doesn't.
You keep the code, the documentation, and the know-how. We offer light support afterwards if you want it.

30 min first.
Two hours if it fits.
Book a 30-minute call and tell us what you're building. If it fits, we follow with a two-hour working session: architecture sketch, honest scope, no invoice.
