Hi,

I have a Z-wave.me USB stick that I am using with zwavejs and home-assistant. In zwavejs the reported FW version is 5.25. It was bought at the end of 2018.

I now need to add a few devices using smartstart, and seemingly I therefore need to update the USB dongle to version >5.32:

Then I have found this tool:
https://z-wave.me/support/zmeserialupdater-manual/
With this map of update:
https://service.z-wave.me/expertui/uzb- ... graph.html

My challenge is that I do not understand the map, and I really, really want to avoid messing up my configuration having to add all nodes again. Could someone guide me to how I can firmware upgrade my USB-stick?

The best is to install Z-Way and do it in Z-Way. This is the simplest. Also make sure to make a backup before you proceed since some sticks had issues with firmware upgrade - they get bricked. Unfortunately, you can not know that in advance ;(
