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

Known Issues

General

  • 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 documentation located within this repo at ./docs/silabs/
  • 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-WiFi interference when connected over the 2.4GHz channel. This is resolved by connecting the chip-tool device to a 5GHz SSID and the end device to a 2.4GHz SSID for the same Wi-Fi network.

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, ~4GB. 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.
  • 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.
  • Matter Shell does not fully work with WF200 with EFR32xG24. Entered commands will not echo back to the terminal, and command outputs will not be seen. However, the commands are successfully processed.
  • RSI Send failure sometimes occurs within 1 hour of commissioning with the RS9116 or SiWx917 with Apple 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.
  • Timeout error occurs after running the Thermostat App for 1 hour or more on the EFR32xG24 + RS9116 device combination.
  • Matter Commissioning sometimes fails with a BlueZ disconnection error with RS9116 (NCP) and SiWx917 (NCP and SoC).

Unify

  • Endpoint 1 of the bridge shows support for the Identify cluster, but identify commands have no effects.
  • The Attribute Illuminance Measurement Type is not parsed correctly from the MQTT Side.
  • Unify Matter Bridge does not do clean shutdown, occasionally the application hans when shutting down.
  • General Diagnostic Cluster: AcceptedCommandList has command 0 listed twice on endpoint 0.
  • Groups Cluster: FeatureMap does not show in endpoint 1, but does show on all bridged endpoints.
  • Some chip-tool tests fails, see the test results in the bridge documentation for details.
  • For OnOff cluster, OnWithTimedOff command when used on a Z-Wave based Unify bridged endpoint, does not function as specified in combination with other OnOff commands.
  • For OnOff cluster, OffWaitTime attribute for a Z-Wave based Unify bridged endpoint calculation gets wrong if OffWithEffect/Off command is sent after OnWithTimedOff command.
