Matter Wi-Fi Direct Internet Connectivity#

• Direct Internet Connectivity (DIC) is a Silicon Labs-only feature to connect Matter devices to proprietary cloud solutions (AWS,GCP,APPLE ...) directly. As such, a Matter Wi-Fi device must support connecting locally on the Matter Fabric, via IPv6, and connecting to the Internet via IPv4.

• Matter devices can be controlled by chip-tool or controller and the respective status of the attribute modified will be published to the cloud.

• Remote user can install the cloud specific application to get the notifications on the attribute status and to control the device.

Feature Design#

End-to-End Set-Up Bring Up#

Message Queuing Telemetry Transport (MQTT)#

MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. Refer https://mqtt.org/ for more details

Configuring the MQTT server#

To set up and configure AWS or Mosquitto for DIC support see the following documentation:

• AWS installation

• Mosquitto installation

Remote User Setup (MQTT Explorer)#

A remote user is used to check the state of device. In this context MQTT explorer is used as a remote user.

MQTT explorer setup and configuration

DUT Setup#

Software and Hardware prerequisites for working with Silicon Labs Matter:

1. Matter Hardware Requirements

2. Matter Software Requirements

3. Use the build command for DIC instead of the normal build command in the Software Setup documentation.

   • Don't use normal build commands

   • Build for DIC

End-to-End Test of DIC Application#

User Setup (MQTT Explorer):

• Sharing status of device to cloud

  • End-to-end command to be executed from chip-tool, refer Running the Matter Demo on EFR32 hosts

  • Below is the application specific attribute/s information or state shared to the cloud through Direct Internet Connectivity Solution

    • For Lighting App, On/Off Attributes

    • For Lock App, lock/unlock Attributes

    • For Windows App, lift/tilt Attributes

    • For Thermostat App, SystemMode/CurrentTemp/LocalTemperature/OccupiedCoolingSetpoint/OccupiedHeatingSetpoint Attributes

    • For On/off Plug App, On/Off Attributes

  • Application status would be updated on the mqtt_explorer UI, as shown in below image.

• Control of the device through cloud interface

  • Make sure matter device is up and commissioned successfully, refer Running the Matter Demo on EFR32 hosts

  • For Controlling the device, set topic name and the commands to be executed in the mqtt_explorer for below applications.

    • Lighting App

      • Topic: command

      • Commands:

        • toggle

        • on

        • off

    • Onoff-plug App

      • Topic: command

      • Commands:

        • toggle

        • on

        • off

    • Lock App

      • Topic: command

      • Commands:

        • lock

        • unlock

    • Thermostat App

      • Topic: command

      • Commands:

        • SetMode/value(value need to provide 1,2,3,4 ex:SetMode/1)

        • Heating/value(value need to provide 2500,2600 ex:HeatingSetPoint/2500)

        • Cooling/value(value need to provide 2500,2600 ex:CoolingSetPoint/2500)

  • Then click publish button to execute the command.

• Download AWS OTA Image through cloud interface

  • Make sure matter device is up and commissioned successfully, refer Running the Matter Demo on EFR32 hosts

  • Make sure device is connected to MQTT Server successfully.

  • Then Create a AWS OTA Job in the AWS Website, refer How to create AWS OTA JOB

  • Trigger OTA Command through MQTT Explorer like below.

  • Then click publish button to execute the AWS OTA command.
