KNX Alternative · Written by installers who program both
Keep the wired reliability.Lose the lock-in.
KNX earned its reputation with thirty years of wired-bus engineering. Loxone gives you the same philosophy — wired-first, locally processed, no cloud, no monthly fees — without ETS licensing, without specialist day rates for every change, and without a project file someone else holds over your home. We install Loxone, we hold KNX expertise in-house, and we migrate between the two.
Why People Look
Nobody searches for a KNX alternativebecause KNX is bad.
They search because of what owning a KNX system is like after handover. These are the four reasons that actually bring people to us — from commissioning and takeover work, not theory.
The project file problem
On KNX, whoever holds the ETS project file holds practical control of your building. If the original integrator retires, folds or just stops answering, a new company may be reverse-engineering your home before they can change a scene. We take these orphaned systems on — and they are projects, not afternoons.
Every change is billed like engineering
ETS is a paid professional tool and the people fluent in it mostly work commercial projects, at commercial day rates. A new scene, a rezoned room, a swapped device — each one is an ETS session. Ten years of small changes is where KNX quietly doubles its price.
The app is not part of the standard
The polished phone control homeowners expect is not in the KNX standard — visualisation comes from a separate server product at a separate price, and it is another thing to license, update and support.
The quote came back and it stung
KNX devices are priced like the professional components they are. For a 4-bed London home, £25,000–£50,000+ with visualisation is the realistic range we see on quotes clients bring us. Good engineering — but you can have comparable engineering for less.
Side by Side
The comparison,without either brochure.
Figures are from our own installations and from KNX quotes clients bring us — methodology, not marketing. The long version, with the programming and takeover detail, is in our KNX vs Loxone guide.
| KNX | Loxone | |
|---|---|---|
| What it is | Open standard, 500+ manufacturers | Single-manufacturer ecosystem (Austria) |
| Where logic lives | Decentralised, in each bus device | Central, on the Miniserver |
| Programming | ETS — paid licence, certified specialists | Loxone Config — free download, any partner |
| App & visualisation | Separate server product, extra cost | Included, free, no subscription |
| Typical 4-bed London home | £25,000–£50,000+ with visualisation | £15,000–£40,000 installed |
| Cost of changes later | ETS reprogramming at specialist rates | Config session, often remote, often under an hour |
| If your installer disappears | You need the ETS project file — or else | Config lives on the Miniserver in your house |
| Strongest at | Commercial, multi-vendor specifications | Residential automation, energy, one ecosystem |
The Honest Bit
Three cases where we wouldtell you to stay with KNX.
An alternative page that pretends the incumbent has no strengths is an advert. KNX is a genuine open standard: 500+ manufacturers on one bus, decentralised logic with no central point of failure, and installations from 1995 still being extended today. That matters in the right building.
A large commercial building with a professional facilities team and a multi-vendor procurement requirement — that is KNX’s home ground.
A specification that genuinely needs a device that only exists in the KNX catalogue. After thirty years and hundreds of manufacturers, it happens.
A well-programmed KNX system you are happy with. Keeping good infrastructure is a fine answer — we say so even though migration is a service we sell.
Already Own KNX?
You don't have torip anything out.
A steady part of our workload is KNX homes moving to Loxone — usually because the integrator has gone quiet, the changes bill keeps growing, or the family wants the app and energy management KNX never gave them. The migration is staged, not scorched-earth.
Keep the bus wiring
The twisted-pair cable through your walls is the expensive part of a KNX install, and it does not need to come out. The Loxone KNX Extension lets the Miniserver talk to existing KNX actuators directly.
Migrate in stages
A takeover usually starts with the Miniserver becoming the brain — logic, app and remote access move to Loxone Config while your KNX dimmers and actuators keep doing the physical work. Devices are then swapped only when they fail or when a room is refurbished.
One app on day one
The family gets the Loxone app, scenes and energy management immediately — without waiting for a full hardware replacement or paying for one.

Questions
KNX alternatives,answered honestly.
What is the best alternative to KNX in the UK?
For residential projects, Loxone is the closest like-for-like alternative: wired-first, locally processed, no cloud dependency and no monthly fees — the same engineering philosophy as KNX, organised around one ecosystem instead of an open standard. Crestron is the alternative at the top of the market (fully bespoke, much more expensive), and Home Assistant at the DIY end (free, capable, but a hobby rather than a product). Which fits depends on the project — our comparison guide covers the decision in detail.
Is Loxone cheaper than KNX?
Usually, yes — on both the install and the decade after it. For a 4-bed London home our Loxone installations typically land between £15,000 and £40,000 with the app, visualisation and logic included. Equivalent KNX specifications on quotes clients bring us run £25,000–£50,000+ once a visualisation server is added. The bigger gap is in changes: Loxone reconfiguration is often a remote session, while KNX changes are billed ETS engineering time.
Can Loxone work with my existing KNX system?
Yes. The Loxone KNX Extension connects the Miniserver to an existing KNX bus, so existing actuators, dimmers and sensors can stay in service while the logic, app and remote access move to Loxone. This is how most of our KNX migrations start — the wiring and the expensive field devices stay, the controls layer changes.
My KNX integrator has disappeared and I don’t have the ETS project file. Am I stuck?
Not stuck, but honestly: without the project file, a KNX system has to be partially reverse-engineered before anyone can safely change it, and that takes time. We hold KNX/EIB expertise in-house and take these jobs on. In many cases the pragmatic answer is a staged migration to Loxone — recover control of what runs the house today, then stop depending on a file someone else holds.
When would you tell me to stay with KNX?
If a well-programmed KNX system already runs your house and you are happy with it. If your project is a large commercial building with a facilities team. Or if your specification requires an open multi-vendor standard or a device that only exists in the KNX catalogue. KNX is good infrastructure — the case for an alternative is about cost of ownership and lock-in, not about KNX being bad engineering.
Who actually writes this comparison — a KNX company or a Loxone company?
Both, which is the point. We are a Loxone certified partner and we hold KNX/EIB expertise in-house; a steady part of our workload is taking over and migrating KNX homes. The comparison comes from commissioning experience on both platforms, not from either brand’s brochure — and where KNX is the right answer, we say so.
