I built a smart home once before, when that meant Wi-Fi lights and switches — and the patience of Job. The novelty wore off. What has pulled me back this year is the prospect of talking to the house using AI voice assistants, using plain language and being understood.
My new setup runs on Home Assistant, an open-source platform, on a dedicated Apple M1 Mac mini. My Victron solar inverter and battery bank report state of charge through a Cerbo GX. A rain sensor updates rainfall totals by the minute and keeps a log. A sensor tells me the outside humidity and temperature in real time, and stores this data too. If someone walks up to my front door, I know they’re there before they even ring the doorbell.
An Olarm Connect alarm knows whether the house is armed and empty. It lets the house make decisions on its own: that the garage door has been standing open for 15 minutes, say, and somebody ought to be alerted about it.
The next step is bridging all of it into the Apple Home app, so I can raise my watch and say “open the garage door” without unlocking a phone or hunting for a remote. It sounds like a small thing. It isn’t.
This is the reason Apple’s expected full-blown entry into the smart home category, possibly as soon as next month’s iPhone 18 event, is worth watching. A house full of connected gadgets is not a smart home. What truly makes a smart home is intelligence; a place you can interact with, especially using your voice; and having it understand what you mean.
According to Bloomberg’s Mark Gurman, Apple is readying three home devices: a refreshed Apple TV and HomePod mini before year-end, and an all-new smart display, dubbed the “HomePad” in some coverage. All of them have waited on Apple’s rebuilt, AI-powered Siri assistant, which is why the hardware has slipped repeatedly since first being tipped for 2025.
The new Apple TV may matter most of all. The current model is already a Matter hub and, in its Ethernet version, a Thread border router. Thread is a low-power wireless mesh for battery-operated sensors and locks, in which mains-powered devices relay traffic for their neighbours; Matter is the interoperability standard backed by Apple, Amazon, Google and Samsung, meant to let a switch bought from one brand work with any big platform. What the box cannot do today is run Apple Intelligence. A faster chip would change that, putting a capable assistant in the living room rather than only in a pocket.
In South Africa, the case for the smart home rests on more than convenience. Load-shedding has receded but self-generation has not, and a household that has spent six figures on solar and storage has an optimisation problem that is fundamentally a software problem.
Add security, water from a tank or borehole and connectivity that cannot always be assumed, and automation stops being a gadget and starts looking like critical infrastructure. It also has to keep working when the fibre is down.
That is why Home Assistant is the counterpoint to Apple. It is open source, talks to almost anything and runs on hardware you own. It is now practical to run a small language model on that same machine as the conversation layer, so the house can be spoken to with no subscription and no round trip to a data centre. Apple will sell polish. Home Assistant offers control. Matter increasingly means consumers may not have to choose between them.
Siri has been poor for a decade and Apple is now betting the category on finally fixing it. The test here is whether the intelligent assistants of the future understand context. “Turn off lounge lamp two” is a remote control with extra steps. “I’m going to bed”, with the house working out which lights are still on, whether the outside beams are engaged, whether the garage is open, whether the doors are locked and what the batteries should do overnight, is the thing worth building.
Good automation should disappear into the background. That means fewer apps, not more, and eventually no app at all, just a sentence spoken to a watch.
Apple invented none of this and is arriving late. The question is whether its arrival signals that the sensors, the standards and the voice models have finally matured enough for mass adoption. I’d wager the smart home is now moving from a hobbyist project for geeks to something more mainstream. And that’s exciting.
