Unify

In order to expose Zigbee and Z-Wave devices to a Matter fabric with the Unify Matter Bridge, you need to set up the Unify ecosystem with a Raspberry Pi 4, Z-Wave, and a Zigbee protocol controller. A more detailed guide on setting up this ecosystem can be found in the Unify documentation.

The Unify Matter Bridge supports bridging the following clusters for Z-Wave/Zigbee devices:

  • Bridge Device Information   
  • Level                       
  • OnOff                       
  • Identify                     
  • Group                       
  • Color Control               
  • Occupancy Sensing           
  • Temperature Measurement     
  • Illuminance Measurement     
  • Pressure Measurement         
  • Flow Measurement             
  • RelativeHumidity Measurement

Controlling the Z-Wave/Zigbee devices is supported with the following Matter controllers:

  • Chip-tool
  • Google Home

Changes in this release:

  • Added missing Dockerfile upgrades required for building the docker image for the Unify Matter Bridge.

Known Issues

General

  • After you sync your development repo to this latest release you may run into build errors such as a ZAP version validation:
    • Checking ZAP from ['zap-cli']: !!! Version validation failed: required at least 2023.4.27, got 2023.4.5 instead
    • This error indicates that your build environment needs to be updated. To do this run bootstrap via the following command: $source ./scripts/bootstrap.sh
  • The Amazon Ecosystem requires additional advertising functionality in the device. The Demo images included in this release DO NOT include this functionality. In order to work with the Amazon Ecosystem a developer must build their device image from scratch including the following arguments: chip_enable_additional_data_advertising=true chip_enable_rotating_device_id=true An example of a build line would be:
  • ./scripts/examples/gn_efr32_example.sh examples/lighting-app/silabs/efr32 out/lighting-app-additional_advertising BRD4186C chip_enable_additional_data_advertising=true chip_enable_rotating_device_id=true"
  • The Matter device images require approximately 700k in flash space. As a result only a subset of EFR32MG12 and EFR32MG2x devices are supported. For a complete list of devices supported consult the Hardware Requirements page in the documentation.
  • Sending 10+ chip-tool commands may result in “Invalid CASE Parameters” error. Fixed by resetting the device.
  • Window app: Current position tilt and configuration status are out of range.
  • Matter SDK Issues (https://github.com/project-chip/connectedhomeip)
    • BLE Connection/Timeout error occurs occasionally during commissioning with the chip-tool running on Raspberry Pi or Linux (project-chip#16178). Running on these platforms requires an access point with both 2.4GHz and 5GHz capabilities. There is BLE-Wi-Fi interference when connected over the 2.4 GHz channel. This is resolved by connecting the chip-tool device to a 5 GHz SSID and the end device to a 2.4 GHz SSID for the same Wi-Fi network.
  • Timeout can sometimes happen during operationalSessionStatus.

Thread

  • Silicon Labs has provided a complete image file for the Raspberry Pi that can be flashed onto an SD card to create the "Matter Hub", which is a Raspberry Pi running Ubuntu and including a pre-built version of the Open Thread Border Router (OTBR) and chip-tool. The image we have provided is quite large, ~4 GB. As a result it can take quite a while to download the .zip file and flash it onto an SD card. Depending on your connection the process could take up to half an hour. Regardless, the demo and development experiences using this pre-built image is a much faster process than building the Matter Hub from scratch.

Wi-Fi

  • The Ozone Debugger may not immediately run the Matter application on the SiWx917 SoC Device. The application runs on resetting the device.
  • When Setting up the Ozone Debugger on Mac the location of the JLinkDevices.xml file has moved, Follow this documentation (https://wiki.segger.com/J-Link_Device_Support_Kit#JLinkDevices_folder) in order to place it in the proper location.
  • OTA Update Bootloading sometimes does not work with WF200 with EFR32xG24. This issue is resolved by applying the workaround described in the Wi-Fi FAQ.
  • RSI Send failure sometimes occurs within 1 hour of commissioning with the RS9116 EVK with Apple/Google Home. To recover from this issue, try one of the following:
    • Reboot the device and wait for 5-10 minutes, or
    • Erase the flash, re-flash the application and repeat commissioning.
  • Commissioning fails with an "out of memory" error when an OpenThread device in the same network was added using an Apple HomePod Mini.
  • Commissioning step 18 failure occurs occasionally:
    • This has been seen to occur more frequently with one specific access point – MI Router 4C
    • When this issue occurs, try the following steps to run commissioning successfully:
      • Delete all files in your chip-tool's /tmp folder
      • Factory Reset your access point
  • TriggerEffect command in Identify cluster does not work on EFR32xG24 with RS9116/WF200.
  • Group commands do not work for one specific access point: ASUS RT-AX88U.
  • Simplicity Commander does not erase the complete flash of SiWx917.
  • Google ecosystem sends a timeout in multi admin long run test.
  • Sometimes the Wi-Fi DUT disconnects from the network in ecosystems testing with Google Home in the long runs. 

Unify

  • The Attribute Illuminance Measurement Type is not parsed correctly from the MQTT Side.
  • Unify Matter Bridge does not do clean shutdown, occasionally the application hangs when shutting down.
  • For OnOff cluster, on a Z-Wave-based Unify bridged endpoint the OnWithTimedOff command does not function as specified in combination with other OnOff commands.
  • For OnOff cluster, on a Z-Wave-based Unify bridged endpoint the OffWaitTime attribute for calculation is incorrect if OffWithEffect/Off command is sent after OnWithTimedOff command.
  • For Identify Cluster, failure in writing to identify-time attribute to endpoint 1 of Unify Matter Bridge.
  • Attribute read of the ColorControl Attributes: Options and EnhancedColorMode fails with some Zigbee devices.
