Need help with flashing Zooz 800 USB stick with v1.5

I’m trying to flash a new, un-used ZST39 LR Zooz USB 800 ZWave stick to the newest firmware. I’m not actually using it yet, I want to have it as a backup, but I want to put the newest firmware on it first. After that, I was going to try and transfer the network to it.

Going to the Zooz site they highly recommend using Simplicity Studio from Silicon Labs to flash it. They warn you repeatedly to do it that way rather than through HA. In my case, since I already have an in-place Zooz 700 USB stick running, I really have no choice (I think) but to use Simplicity Studio.

The problem is, I can’t. It doesn’t get recognized in Windows, both on a stand-alone Windows 10 machine or my Virtualbox client Windows 10. It does not see the stick. As an aside, Simplicity Studio does not seem simple. It seems like overkill and I couldn’t even see through the menus how flashing is done.

I did some reading, there are some silicon labs universal drivers, but no difference, it was still not recognized. BTW, they also have a Linux install, and I did try that first, but no success there either.

So my question is, has anyone been able to update the stick using Simplicity Studio, or is there some way I can do this through HA without messing up my existing z-wave network.

Thank you

You can use the Z-Wave JS flash utility to update it. It’s the same code used by HA or Z-Wave JS UI for upgrades. https://github.com/zwave-js/node-zwave-js/blob/c21f13734d3283fde6dc5ede1535bc6be33c12f3/packages/flash/README.md

As for Windows, you might need updated drivers. https://www.wch-ic.com/products/CH9102.html The Zooz 800 does not use the Silicon Labs USB bridge so those drivers won’t help.

Or, it looks like the Homeseer controller is using the same USB chip, as they are providing the same drivers: https://docs.homeseer.com/products/updating-z-wave-firmware-for-smartstick. Additionally, you can download their firmware package as it includes PC Controller, no need to install Simplicity Studio. Just use the Zooz firmware file instead.

I will try the Github route first. Thank you.

I have the same issue here, except that it’s Simplicity Studio on a Mac that simply doesn’t match up to any of the directions off the Zooz update KB page, which references a Settings page that as far as I can tell from looking into every obscure menu that I could find in that app, simply doesn’t exist.

Being < 3h into my first HomeAssistant usage on a prebuilt HA Green box the GitHub update route makes no sense to me so I’ll just keep this stick frozen at v1.4 and hope for the best.

Simplicity Studio is an IDE (developer environment). It doesn’t provide any capability to upgrade firmware. The Microsoft Windows version of Simplicity Studio can install the PC Controller software (Windows only) which can be used to flash the firmware. Luckily you can upgrade the firmware using HA on your Green, or even the Mac with ZUI or the flash utility I linked above, so I’m not sure why you are bothering otherwise?
