So far I have:

  • Migrated from zigbee2mqtt to native ZigBee integration - Having problems in both makes me suspect the firmware
  • Upgraded and downgraded the dongle firmware - Current firmware 7.4.4.0
  • Replaced usb extension cable
  • Tried running via usb 2.0 hub
  • Tried both usb2 and usb3 ports in my Dell Mini-PC running HAOS.
  • Disabled Frigate to ensure CPU is not to busy.
