Note: The number differences between I, II and III series don't represent feature or bug fix equality as there are different underlying Zigbee stacks in use.

ConBee III (Silabs)

Important: Before flashing new firmware always make sure to create a backup in the Phoscon App. If after an firmware update settings network problems arise, please refer to Wiki: Network Lost Issues for instructions how to restore previous network configuration settings.

  • Initial shipping firmware.

ConBee II and RaspBee II (R21)

• 0x26780700 Beta 2022-05-15
  • Improve handling the case when an end-device switches parent from router to the coordinator.
  • Improve handling of neighbor table, preventing registered end-devices not to be replaced by routers.
  • Improve network robustness for various devices from Ikea and Osram.
  • Fix ZCL default response handling for manufacturer specific commands.
• 0x26720700 Stable 2021-08-20
  • Fix invalid ZDP Parent Announce responses (relevant for IKEA routers)
• 0x26710700 Stable 2021-08-18
  • This version is for RaspBee II and includes all changes from 0x26700700.
  • Improved stability of the UART communication.
• 0x26700700 Stable 2021-08-11
  • This version is for ConBee II only
  • Fix loopbug behaviour caused by a USB stack bug.
  • Force end-device to MAC poll once more by using the MAC layer frame pending flag
  • Improved serial communication performance.
  • ZCL Default Responses for ZCL profile wide commands, e.g. attribute reports, and IAS notification status change commands are now handled directly by the firmware. This prevents devices from becoming lost when no host application runs, e.g. after a restart.
    Note: Projects which use the serial communication protocol don't need to change anything — the firmware replies with APS confirm status = success for ZCL Default Response commands sent by the host application, if they were already handled.
  • The maintenance of directly connected end-devices was improved.
• 0x266f0700 Beta 2021-07-13
