Hello folks,
did someone a Z-Stick Gen5 V1.01 firmware update (page modified on: Mon, 31 Aug, 2020 at 3:57 PM) already?
Aeotec Changelogs
If so, is the ZW090 (-A/B/C) still running with z-wave binding?
Or is that old stuff? (IIRC latest version was V6.51.06??)
Thanks a lot! 
interesting, but link does not seem to work for me…

Yesterday, the link was running well. I don’t know why it is gone.
Fortunately, I saved the page as a pdf.

Perhaps they pulled back the update due to issues.
In HA forum there is an interesting topic
The initial release of this stick runs Z-Wave library 3.95, SDK version V6.51.02 and firmware version V1.00 - Some of these units can be updated to the newer V1.01 firmware but not all of them. These sticks don’t work on a Pi4
So indeed, maybe some of them can’t be upgraded and give problems?
To bad there is no change log what actually is fixed/improved with higher SDK
You mean there is some bleeding when you’re on the bleeding edge of upgrades? 
These are only issues at the network layer - the stick doesn’t have any application level functionality as all application level stuff (eg all the command class implementation) is performed in the binding only. In general, this means that updating the firmware will likely not make any observable change from a user perspective.
…unless said firmware breaks communication…
I also did further investigations:
According to the following data sheet there are the following firmware versions on the stick:
| Version__ | Name on Sticker___________ | Firmware | SDK | API | SmartStart | RPi4 compatible____________________ |
|---|---|---|---|---|---|---|
| Version 1 | Z-Stick Gen5 | 1.00 | v6.51.02 | 3.95 | no | Not without unpowered USB Adapter |
| Version 2 | Z-Stick Gen5 | 1.01 | v6.51.10 | 4.54 | no | Not without unpowered USB Adapter |
| Version 3 | New Z-Stick Gen5 | 1.01 | v6.51.10 | 4.54 | no | Yes, works without USB adapter |
| Version 4 | Z-Stick Gen5+ | 1.02 | v6.81.06 | 6.07.00 | yes | Yes, works without USB adapter |
