The smart home buyer's checklist

A smart home is a ten-year decision. The wiring goes in during construction or a substantial renovation, the devices stay on the wall for at least the lifetime of one phone cycle and usually several, and the buyer typically lives with whatever they specified for far longer than they expected to.

Most buyers spend more time choosing a coffee machine than they spend understanding the smart home they are about to install, which is why the first frustrations of living with one tend to feel like a surprise.

This article turns the principles of the first five articles into ten practical questions every buyer should ask before signing off on a specification. The questions are in three groups: questions for the install itself, questions about what happens when something breaks, and questions about how the system behaves over the years that follow.

Each one is short, answerable, and useful regardless of whether the buyer is specifying a single home, a renovation, or a development of fifty.

Before the system goes in

The first three questions are about the act of installation, and they are the easiest to test against any smart home spec the buyer is being shown.

Question 1: Who installs it, and what training do they need?

A system that requires a specialist contractor to commission has higher install cost, longer wait times, and a smaller pool of people capable of servicing it later. A system that any qualified electrician can install and commission has lower install cost, faster turnaround, and a vastly larger service pool when something needs attention five years from now.

The honest answer to this question often reveals more about the system than any spec sheet does.

Question 2: Is the wiring standard or proprietary?

Standard Australian wiring practices mean the trade installing the system can use the same techniques and materials they already use, which is faster, cheaper, and less prone to specification errors. Proprietary cabling means the trade has to be trained on the specific system, has to source specialist parts, and has to do something different from how they wire every other electrical job in the house.

If the wiring is proprietary, the buyer is committing to that specific vendor's continued existence.

Question 3: How long does commissioning each dwelling realistically take?

Commissioning time scales directly into the per-dwelling cost on a development build, and into the buyer's experience of "when does this become useful" on a single-home build. A system that takes thirty minutes or hlaf a day per dwelling to commission is a fundamentally different product than one that takes a full week per dwelling, even if the device list looks similar on paper.

When something breaks

The next three questions are about what happens after handover, when the smart home is in daily use and something inevitably stops working as expected. These are the questions that separate the buyers who live happily with their smart home from the buyers who quietly stop using it after the first frustrating failure.

Question 4: What happens when the home internet drops, or the NBN goes down for an afternoon?

A smart home that depends on cloud servers for routine operation stops working when the internet stops working, even for things as basic as a wall switch. A smart home that runs locally, with cloud services as an extension rather than a foundation, continues to do its job through internet outages. Australian internet is generally good but rarely perfect, and the buyer should know in advance whether their lights still come on during a rainy Sunday evening NBN dropout.

Question 5: Can a regular electrician service it five years from now?

The serviceability question matters more than it looks.

If the answer involves a specialist contractor, a discontinued hub, or an app the manufacturer no longer maintains, the buyer is signing up to be stranded if the original vendor goes through any kind of business change. If the answer is "any qualified electrician can swap any device with the standard tools they already own", the system has a long, defensible service life ahead of it.

Question 6: Who carries the support burden after handover?

This question is particularly relevant for developers, but matters for every buyer. When something goes wrong six months after move-in, who takes the call, who diagnoses the issue, and who pays for the resolution?

A clear answer here, with a named responsible party, is the difference between a smart home that gets supported and a smart home that becomes the homeowner's problem alone.

Over the life of the system

The final four questions are about durability over the years that follow. They are the questions buyers least often ask and most often regret not asking.

Question 7: What happens if the platform vendor changes their pricing or restructures their app?

The smart home category has a history of vendors introducing subscription fees, removing features, or changing app architectures in ways that disadvantage the existing installed base. The buyer should know in advance whether they are buying into a stable, owned platform or a vendor relationship that can be repriced or restructured later.

Question 8: How does the system handle the household changing ecosystems?

The household running iPhones today might run Android in five years, or vice versa. A smart home that works with multiple ecosystems means the buyer can switch their phone without rewiring the house. A smart home tightly bound to one ecosystem locks the buyer in for the life of the system, even if their preferences change.

Question 9: Is the manufacturer Australian, and what is their track record?

Australian manufacturers tend to be more accountable to Australian buyers and more responsive to Australian conditions, including the wiring standards, ripple control quirks, and climate considerations specific to the market. Track record matters too: a manufacturer with a fifteen-year history of supporting their installed base is a different proposition from one that arrived in market last year with a strong marketing campaign and a thin product line.

Question 10: Does the product line extend, or get abandoned as new generations come out?

This is the long-tail durability question. When the manufacturer ships a new generation of products, do the older ones continue to work alongside the new ones, or do they become an "upgrade required" sales opportunity?

Honest manufacturers extend their installed base; less honest ones abandon it.

The buyer can usually tell which kind they are dealing with by looking at how the manufacturer treated the previous generation when the current one launched.

What good answers look like

A buyer who can ask these ten questions and get good answers from the manufacturer or the installer is most of the way to a confident specification. A buyer who gets evasive answers, or hears "we are working on that" too many times, has learned something important about the product before they commit. The questions are short.

The answers either come quickly or they reveal that nobody at the table knows the answer either, which is itself the answer.
