Is the Zooz 800 Series Z-Stick okay?

I recently upgraded my Z-wave stick to the Zooz 800 Series Z-Wave Long Range S2 USB Stick ZST39 LR. After I installed it in Home Assistant, I got this following message:

Controller firmwares based on Z-Wave SDK: 7.19.3 have a bug that causes the controller to randomly hang during transmission until it is restarted. It is currently unclear if this bug is fixed in a later firmware version.

I checked the firmware of the ZST39 LR and it is version 1.2 which is based on Z-Wave SDK version 7.19.3.

Is this bug something that I need to worry about?

personally I’ve had no issues, same stick. where as I’ve had issues with the aoetec 700 series, night and day difference with the Zooz

Wish you luck.

I think it’s fine for most people. The bug mentioned affects a subset of users. You won’t know until you start using it. Supposedly a fix is being released in a new firmware this month.
