Apple HomeView brings a new way to experience the connected home — and home safety is part of that experience.
Sensereo MS-1 Interlink goes one step further.
It brings smoke detection directly into Apple Home through Matter over Thread, while connecting compatible alarms across the home through Thread-based Interlink.
The result is more than just a smart smoke alarm. It is a whole-home protection layer built for the Apple Home experience.

The One Alarm Built for Apple.
MS-1 Interlink itself is the interlinked smoke alarm connected to Apple Home through Matter over Thread:
MS-1 Interlink detects smoke → Apple Home receives the alarm event
There is no need for another device to first listen for the alarm sound.
MS-1 Interlink can detect, communicate, and become part of the connected home itself.

Whole-Home Protection Goes Beyond a Phone Notification
A notification is useful when you are looking at your phone.
But inside the home, the most important warning is still the alarm people can hear.
That is where MS-1 Interlink adds another layer.
Compatible MS-1 Interlink alarms communicate with each other over Thread. When one alarm detects smoke, the alarm event can be shared across the local Thread network so other connected alarms can also sound.
A smoke event downstairs does not have to remain a downstairs warning.
It can become a whole-home warning.
This is especially valuable in:
-
Multi-story homes
-
Homes with several bedrooms
-
Larger floor plans
-
Homes where sleeping areas are far from kitchens or living areas
And because the alarm-to-alarm communication runs over the local Thread network, the Interlink function can continue even if Wi-Fi or internet access is unavailable, as long as the local Thread network remains active.
One Apple Home. Multiple Layers of Protection.
The strongest part of this setup is that these technologies do not need to compete with each other.
HomeView can continue listening for traditional alarms already installed in the home.
MS-1 Interlink can communicate directly with Apple Home through Matter over Thread.
And multiple MS-1 Interlink alarms can communicate with each other over Thread to extend the audible warning across the home.
That creates three complementary layers:
Sound awareness HomeView can recognize the sound of existing smoke and CO alarms.
Smart home awareness MS-1 Interlink brings smoke alarm events directly into Apple Home through Matter over Thread.
Whole-home awareness Thread-based Interlink allows compatible alarms across the home to respond together.

Built for the Whole Apple Home
MS-1 Interlink is not just a smoke alarm that happens to connect to Apple Home.
It is designed for a home where safety is part of the same connected experience as everything else.
Matter over Thread brings the alarm into Apple Home.
Thread-based Interlink extends the warning across compatible alarms throughout the home.
And HomeView adds another layer of awareness for the alarms already around you.
Together, they make home safety feel less like a separate system and more like part of the Apple Home itself.
