The Echo in your kitchen got a new personality this year. Nobody asked you first.

Two of the biggest smart home companies on the planet just ran a live demonstration of what "your house runs on someone else's server" actually means, and it happened this year, not in some hypothetical future.

Starting in February, Amazon opened Alexa+, its generative AI assistant, free to its entire US Prime base, more than 200 million members. Multiple outlets reported that Prime-linked Echo devices were being auto-upgraded without a prompt or an opt-in, so owners had no warning before their kitchen speaker started talking differently. People logged on and found a different voice, a different personality, proactive suggestions nobody requested, and a longer memory of past conversations they hadn't agreed to.

The complaints piled up fast: slower responses, ads where there weren't ads before, a tone some users described as having "attitude," and at least one basic feature, reading Kindle books aloud, that quietly stopped working. Regulators overseeing the EU AI Act are now watching the rollout for consent and transparency problems, and Amazon has since said it will add opt-in prompts for future upgrades. Which is another way of admitting this one didn't have any.

Google did the equivalent thing from the other direction. Nest Aware, the subscription that used to cover camera history and smart alerts, has been folded into a new Google Home Premium tier at $10 a month for the Standard plan and $20 for Advanced. Features that used to come with the camera you already bought, like meaningful video history and AI notifications, now sit behind that paywall. PCWorld's headline for it was blunt: a "paywall scare."

This isn't the story I told you in June

I've written before about smart home companies that go under and take your automation with them, Insteon's servers switching off overnight, Revolv's "lifetime subscription" hardware bricked eighteen months after Google bought and killed it. That's one failure mode: the company dies, and your house dies with it.

This is a different, arguably worse one. Amazon and Google aren't going anywhere. They're thriving. And that's exactly the point, because it means they can reach into hardware you already own and already paid for, and change what it does, what it costs, or how it behaves, on their schedule, not yours. You don't need a company to go bankrupt for you to lose control of your own house. You just need it to update the terms.

What a wired, open standard does instead

None of this happens with KNX, and not because of some marketing promise, because of how the system is actually built. KNX is an open standard maintained by an independent association, not a product line owned by one company chasing a subscription model. Devices talk to each other over a physical bus, not a cloud account. Nobody can push a personality update to your porch light or start billing you monthly for a feature your switch already had the day it was installed. An installation from before 2000 still runs exactly the way it did on day one, because no single company holds the switch that could change that.

I bridge that world to voice assistants and Matter through 1Home where a client wants Alexa or Google convenience layered on top, and that's a fine thing to want. But the automation itself, the lighting, the climate, the security, doesn't live inside Amazon's or Google's roadmap. It lives on your bus, in your walls, under your control.

The question this actually raises

If your home's core systems depend on a cloud account, ask yourself what happens the day that company decides your paid-for hardware needs a new personality, or your free feature needs a credit card. Both of those things happened to real people this year, not in a thought experiment.

If you're planning a build and want systems that answer to you and not a quarterly product roadmap, get in touch. Just a conversation about what the project needs.
