The Connectivity Standards Alliance (CSA) dropped two notable updates that work in concert at its annual Unify event this week: Matter 1.6 and Product Security 1.1. Together, the releases push smart-home setup toward being easier and more intuitive for everyday users — including the tens of millions who rely on Apple Home — while raising the security bar for connected devices worldwide.
New Matter smart-home standard updates improve smart-home setup, sharing and security
If you’ve ever wrestled with a ceiling light fixture or an in-wall switch while trying to get it onto your home network, the new Matter 1.6 update targets exactly that frustration. The top new Matter standard improvement unveiled at Unify, NFC-Based Commissioning, lets you pair a device with your home ecosystem using a simple tap — even before the device has power.
Earlier Matter versions supported NFC tags as a way to kick off setup, replacing the need to scan a QR code. But Bluetooth LE still did the heavy lifting to complete the process. Matter 1.6 goes further: the entire commissioning exchange can now happen over NFC.
What does that look like in practice? A light bulb can pair with your network before you screw it into the ceiling. An in-wall switch can finish setup before you restore mains power. For bigger installs — a new construction project, a rental property refresh — multiple devices can run through provisioning all at once, then simply activate when they reach their final spots.
For Apple Home app users, this could meaningfully speed up the experience of adding devices that today require awkward physical contortions to reach a QR code.
Joint Fabric simplifies device sharing across ecosystems
Apple Home users who also run Google Home, Amazon Alexa or another platform know the friction of adding a device to each ecosystem separately. Matter 1.6 takes a significant step toward eliminating that.
The new Joint Fabric feature lets multiple user-authorized controllers co-administer a single shared Matter network. Any device added to the Joint Fabric becomes accessible to all participating controllers, and a device’s participation counts as a single fabric toward its capacity limit — meaning it can still join traditional ecosystem fabrics at the same time.
This differs meaningfully from earlier Multi-Admin approaches, which share device access between separate ecosystem networks rather than building a common one. Joint Fabric suits households running more than one platform, professionally managed properties, and new construction handovers where multiple parties need coordinated access from day one.
Smarter thermostats that listen to context, not just commands

Matter 1.6 also rethinks how smart thermostats receive instructions from automations and third-party apps. Today, a controller can fire a direct command at your thermostat regardless of what you just manually set. Matter 1.6 changes that dynamic with Thermostat Suggestions.
Rather than a controller issuing a direct command, it submits a time-bound recommendation tied to one of the thermostat’s supported presets. The thermostat then weighs that recommendation against user-defined preferences and current conditions before deciding whether to act. If your thermostat detects that someone just adjusted it by hand moments ago, it can recognize a fresh incoming suggestion as likely unintended and defer.
This also protects utility demand-response enrollments and user preferences around energy savings, humidity or air quality. It honors those settings even when automations from multiple ecosystems send conflicting signals.
Other enhancements in Matter 1.6
Beyond the headliners, Matter 1.6 ships several targeted refinements:
- Devices can now communicate their operational limits in a standardized way, giving controllers a more accurate picture of what a device can do.
- Security sensors gain the ability to share event history across ecosystems.
- Smoke and CO alarms can flag when someone removes them from their mounting position.
- And certificate revocation infrastructure gets more scalable through smaller, independently updated partitions — important as the number of certified Matter devices keeps growing.
Product Security 1.1 raises the bar for IoT certification
Running alongside Matter 1.6, Product Security 1.1 updates the CSA’s certification program in ways that matter to anyone buying a smart home product carrying its badge.
The previous version of the program focused on individual devices. Version 1.1 expands that scope to encompass complete Internet of things (IoT) systems — including apps, remote processes, and gateways — and introduces two distinct levels of security assurance. Level 1 relies on a manufacturer self-assessment reviewed by an authorized lab, while Level 2 requires full independent testing by that lab.
The update also tackles a real-world problem for device makers: navigating cybersecurity regulations that differ across regions. Version 1.1 now covers the EU Radio Equipment Directive harmonized standards and Singapore’s Cyber Security Labeling Scheme, reducing the duplication manufacturers face when certifying products for multiple markets.
For Apple users, that certification expansion means products bearing a Product Security badge carry more meaningful, independently verified assurance — not just a self-reported checklist.
When will these features reach your devices?
CSA has released the Matter 1.6 specification and software development kit (SDK) for device makers and platform developers to begin integrating. How quickly features reach products in consumers’ hands will vary by manufacturer and product type.
Keep an eye on announcements from your favorite smart home brands — and from Apple — for timelines on when these capabilities land in the devices and apps you already own.
As for Product Security 1.1, CSA said this:
