Primary Matter device vendor Aqara saw its S100 smart switch certified by the Connectivity Standards Alliance (CSA), revealing Aqara’s bold move toward in-depth Matter integration. Initially announced at CES earlier this year, the touchscreen switch S100 US represents one of Aqara’s ambitious attempts to tap into the Matter ecosystem with customization, Thread radio support and built-in sensors.
Matter-enabled Thread border router (TBR)
Almost all TBRs on the market, including Aqara ones, are initiated and integrated with a specific vendor ecosystem, meaning the platform holds admin access and management rights. As a result, users have limited control outside vendor-specific functions. For instance, you typically cannot change the channel or add the router to a different ecosystem.
Many vendors are now trying to break this lock-in via HomeKit, Google Home APIs, or OTBR Rest APIs, but these approaches remain vendor-specific and place more development pressure on end-device makers, an issue Matter aims to address. The Aqara S100 is the second device we’ve spotted with a Thread border router management cluster, following the SMARTWIZ+ art.
The cluster lets users add the TBR to their home network and Matter platform, enabling management and configuration of the Thread network via Matter. At the moment, SmartThings is the only major platform that has announced support for this Matter feature. As more devices with this cluster are certified and become available, other platforms should add support as well.
All-in-one light switch
The S100 light switch integrates two relays, a small display, two switches, a presence sensor and a light sensor.
Aqara Touchscreen Switch S100 US
A dual-button smart wall switch with an integrated touchscreen for both manual and interactive control of connected Aqara devices and automations.
As a regular wall switch, it can control two loads such as lights and fans via the built-in relays. The compliance files show they will appear as on/off lights on Matter platforms.
In addition, there are eight switch clusters, which can expose configurable controls through Matter or bind devices on the Aqara platform. The Matter specification defines multiple switch types for this cluster, including latching switch, momentary switch, action switch and their variations. We expect these to map to the physical keys or to appear on the 1.3-inch display.
The occupancy sensor is likely a 24 GHz mmWave radar for human detection and can be used as a trigger in Matter platforms, according to the compliance files.
However, the light sensor is missing from the Matter capability; it appears to be used only to dim the touchscreen.
Availability
The S100 is a US-exclusive switch for now. Aqara told Matter Alpha it will be available near CES 2026.
