Which System Do You Have? Control4, Crestron, Savant, Lutron

If you bought a house with automation already in it, or inherited a system from an installer who's gone quiet, the first useful thing you can do is work out what you actually own. Not for bragging rights — because it determines who can service it, what it costs, and whether you can do anything yourself.

It's also more confusing than it should be, because most houses have two systems, not one.

The quickest way to identify it

Look at three places:

1. The keypads on the wall. The brand is usually printed on the faceplate or the bezel.
2. The rack or equipment closet. This is the real answer. Find the boxes, read the labels, photograph them.
3. The app on your phone. Whichever app the household uses to control things tells you the head-end system.

Then note the model numbers. They matter more than the brand — a Control4 HC-800 and a Control4 CORE 5 are separated by roughly a decade of capability, and advice for one is wrong for the other.

Most houses have two systems that talk to each other

This is the part that confuses people. A very common setup is Lutron for the lighting and shades, Control4 for everything else — the TVs, audio, cameras, thermostats, and the app that ties it together.

Two separate systems, two separate processors, connected by a driver so that pressing a Control4 button can trigger a Lutron scene.

This explains a symptom that otherwise makes no sense: your lights work perfectly from the wall, but the app says everything is offline. The Lutron system is fine and running independently. What's broken is the link between them — usually because the Lutron processor's network address changed after a router was replaced, and the Control4 driver is still pointed at the old one.

If that's your situation, the fix is small and specific. It is not a failed lighting system.

What the differences actually mean for you

Ignore the marketing comparisons. What matters when you own one:

Control4 — the widest dealer network of the four, which matters most when you need someone. Configured with dealer-only software (Composer Pro), but with a homeowner tool (Composer HE) for editing what already exists, and on X4 a Routines feature that lets you change a fair amount from the app. Practical upshot: easiest to find help, and the most you can do yourself.

Crestron — the most capable and the most bespoke. Systems are often written as custom code rather than assembled from drivers, which means the person who programmed it may genuinely be the only one who understands it. Powerful if you have a relationship with a programmer, difficult if you don't. Practical upshot: hardest to inherit.

Savant — a smaller dealer network than Control4's. If your installer disappears, finding a replacement can take longer depending on where you are.

Lutron — worth separating, because Lutron makes several tiers that behave very differently:

• Caséta — retail. You can buy it, install it, and program it yourself in the app in an afternoon. No dealer needed at all.
• RA2 Select / RadioRA 3 — a middle tier, generally through a dealer.
• HomeWorks QS / QSX — the top tier, and programmed in Lutron's own software behind a certified installer account. This is the one where you need a credentialled person in the loop.

Knowing which Lutron tier you have changes everything about what's possible. If it's Caséta, a lot of what people pay for is genuinely a do-it-yourself job.

The question that matters more than the brand

Whatever you have: does anyone hold a backup of your project?

The programming — every light load, every keypad button, every connection — lives on the processor. If your original installer never handed over a copy, that box holds the only record of it in existence. That's fine until it isn't: a failed processor or a well-meaning reset and the house gets rebuilt from scratch.

Ask whoever installed it for the project file. If they've gone quiet, getting a backup taken should be the first job for whoever takes you on. This applies to every brand.

If you're deciding what to put in

The honest advice is duller than the comparison articles:

• The relationship matters more than the brand. All four make good equipment. What decides how you feel about your system in five years is whether someone answers when it misbehaves.
• Ask, in writing, that you get a copy of the project file when the job is finished. This is the single most valuable thing you can negotiate and it costs nothing at install time.
• Ask who else can service it. A system only one person understands is a system you don't fully own.
• If your needs are modest, they may be genuinely modest. Lighting and shades in a normal house, with no whole-home audio or video distribution, may not need a head-end system at all. Caséta plus a few Picos does more than people expect.

Working out where you stand

Four things, and you can get them all yourself: the brand and model of the main processor from the rack, the OS or firmware version from the status screen, whether there's a second system (usually Lutron) alongside it, and whether anyone has a backup.

Send us those and we'll tell you what you have, what it can still do, and what it would take to get someone looking after it — including when the honest answer is that you don't need anyone. We work on Control4 and Lutron remotely; if you turn out to have Crestron or Savant, we'll say so rather than pretend otherwise.
