Loxone vs Home Assistant: Professional System or DIY Platform?

We install a system that costs thousands. Home Assistant is free. It would be easy for us to be dismissive about it, and that would be dishonest — it’s a genuinely remarkable piece of software, and for the right person it’s the better answer.

Here’s how we’d actually compare them.

What Home Assistant is

Open-source home automation software you run yourself, usually on a small mini PC or dedicated device. It integrates with thousands of products — including many that refuse to talk to each other otherwise — and its automation engine will do essentially anything you can specify. There’s an active community, frequent updates and no licence fee.

The catch isn’t capability. It’s that you are the integrator.

The comparison people don’t make

The 11pm test

This is the question we’d put to anyone weighing it up.

It’s 11pm. Something has stopped working — the landing light, the heating, the front door. Who fixes it, and how long does it take?

With a professional wired system, the honest answer is that the landing light almost certainly still works, because it’s wired and the switch operates at the electrical level regardless of what any software is doing. If something genuinely has failed, you phone someone whose job it is.

With Home Assistant, the answer is you. Usually that’s fine — often it’s a five-minute fix and some people enjoy it. But it’s you at 11pm, and it’s you when you’re on holiday, and it’s you when an update to an integration breaks something you set up two years ago and no longer remember.

That’s not a criticism of the software. It’s the actual product difference, and it’s what the money buys.

Where Home Assistant is clearly the right call

• You enjoy this as a hobby — genuinely the best reason, and a very good one
• Your budget is under a few thousand pounds
• You’re renting or moving soon
• You want to integrate specific devices no professional platform supports
• Avoiding vendor lock-in is a principle you hold strongly
• You’re technical, and you’d rather own the problem than pay someone else to

If several of those apply, don’t call us. Buy a mini PC and have a good time — you’ll get a more capable system than most professional installs, for a fraction of the cost.

Where a professional system earns its price

• Nobody in the house wants to maintain it. This is the most common reason people move from DIY to professional, usually after a couple of years.
• The wiring matters. Lighting control done properly is an electrical installation, not a software project. It needs a qualified electrician and Part P notification regardless of platform.
• Someone else must be accountable. Warranty, response times, a person to call.
• It has to survive you. A house sale, a change in health, a partner who was never the one maintaining it.
• Reliability is non-negotiable. Wired switches that work at the electrical level whatever the software is doing.

Running both

Worth knowing: it isn’t strictly either/or. Some of our customers run Loxone for the wired infrastructure — lighting, heating, blinds, the things that must never fail — and Home Assistant on top for dashboards and for integrating consumer devices Loxone doesn’t natively support.

For a technical owner that’s arguably the best of both: professional reliability underneath, unlimited flexibility above, and if the Home Assistant box dies the house carries on working.

The honest summary

Home Assistant is the better product for a technical enthusiast with time. A professional wired system is the better product for someone who wants a house that works and doesn’t want to think about it again.

Neither of those is a compromise. They’re different purchases, and the mistake to avoid is buying one while expecting the other.
