SONOFF Zigbee 3.0 USB Dongle Plus V2 updates

Hello folks

I have installed a SONOFF Zigbee 3.0 USB Dongle Plus V2 onto my HA Server. I’ve not flashed it or anything, and so far all is working fine. However if there are firmware updates, how would one go about doing it.


Hello folks,
sorry to bump this again, but is anyone able to advise how to upgrade the firmware. The reason I ask is that I am now running into issues with the latest HA update (2023.09.2) where some of my devices connect and others either eventually connect after a while, or don’t at all and then I have to restart HA.

Below is extract from my diagnostic file which I believe is the current Firmware I am running

data": {
    "config": {},
    "config_entry": {
      "entry_id": "83cb51c2decbec61d2513d6b0b48924d",
      "version": 3,
      "domain": "zha",
      "title": "SONOFF Zigbee 3.0 USB Dongle Plus V2",

          "flow_control": "software",
          "baudrate": 115200
        "radio_type": "ezsp"

thanks in advance
