HUSBZB-1 (Combo Zigbee and ZWave stick) Should I bother flashing its firmware to latest?

Running on an Ubuntu 20.04 server
As reported by OH3
Zigbee firmwareVersion
ZWave firmware version is not reported in OH3

Both controllers are online in OH3

I don’t have any Zigbee or Zwave devices just yet.

I saw somewhere in my googling that updating the HUSBZB-1 firmware is possible

Has anyone here tried to update the firmware? Would updating the firmware give me anything useful?

If you can find firmware, then yes, new firmware is really essential as the firmware in these devices is now very old and it will not support many of the newer devices on the market (ie Zigbee 3.0 devices). You may find devices join the network, then leave again a few seconds later as a result of this.

I dont have one of these but some time back someone here told me there was no bootloader installed - if that’s incorrect then flashing newer firmware would be highly desirable.

it worked


Cool - thanks for sharing. I would definitely recommend anyone with this device does this upgrade.

Great find! I too was under the impression that this coordinator couldn’t be upgraded. I’m off to upgrade as well. I like they provide a docker container to do the upgrade. Definitely saves some effort.

So… any reason to flash the Z-Wave side?

I found a guide, but it’s a bit scary as it requires cracking open the plastic housing and shorting a pin

Oh golly…
I opened up the stick and the pins to short while flashing are tiny tiny tiny.
I will not be attempting to flash Z-Wave firmware.

Did you find a material difference with the reliability of your Zigbee network after flashing the stick?

My zigbee network is small right now and doesn’t do much where I would notice a difference. It’s basically five smart plugs, three of which are not even in use, one drives a humidifier when the humidity drops too low (which doesn’t often happen in the summer) and the other controls a lamp which is automated. I don’t see anything different in the logs.

I didn’t really expect the performance to improve with the flashing. I did it more to support newer devices and such.

I would not in general expect reliability to change. The big reason to flash to a newer version is compatibility with newer devices. The old firmware will not work with many new devices being sold now - otherwise there is nothing really wrong with the older firmware.

It will be interesting to see how the Zwave devices I get will compare to the Zigbee devices I get.

Will I run into ZWave devices not working well or not at all with the HUSBZB-1.

I’m kind of disappointed that flashing the ZWave side is such a fraught proposition.

No - it will be fine. The stick doesn’t do so much on the ZWave side - most of the heavy lifting is done in the binding.

Well… I went and did it anyway

This link suggested a much easier pad on the stick to short and it was still fiddly, but doable.
I now am running a much more current Z-Wave firmware on my HUSBZB-1 stick


According to the guide, the specific Z-Wave features mentioned as enabled are

  • Updated Z-Wave Library features
    • New Serial API features (tested)
      • Official NVM backup/restore functions
        • A side note: you can backup the stick already with tools like Z-Stick Gen5 Backup Tool, or the ZMESerialUpdater tool. I have successfully cloned a stick using this method. There is also a method to backup the zigbee portion with a different tool, which I’ll probably make a guide for in the future. The api and format of the backup are different though vs using the official api method here.
      • Transaction report information on received frames
        • RSSI info, routes taken, latency
    • SmartStart (untested)
    • S2 encyption (untested)
  • Can flash different Z-Wave firmwares
    • Official Bridge/Static firmwares
      • The stick could be used with Z/IP gateway projects as that requires a bridge firmware, and series 700 chips only have bridge firmware available to them. This is/was the go forward for certified Z-Wave controllers, but I’ve heard rumors that the serial api could be certified for use with 700 series chips in the future.
    • Zniffer firmware.
      • Allows you to sniff z-wave packets

So… are any of these features implemented or interesting in OH3?

No. As I mentioned earlier, a lot of this is a feature of the binding (eg S2 security and SmartStart) and not part of the dongle firmware.

Thank you
So I risked bricking my husbzb-1 dongle for no actual benefit. :confounded:

Well, I did say this earlier that most of the work is done by the binding…
