If you want/need new Z-Way features, please consider buying a new SD card and installing bookworm and Z-Way on the new SD card. Buster was deprecated over a year ago and is no longer receiving security updates. You can then copy the /opt/z-way-server directory from your old SD card to the new SD car...

No need to stress. You should be able to exclude the device and re-include it again with the correct S2 key. The exclude (and include) Z-Wave management commands are on the Expert UI->Network->Control page. If you can't exclude the device and re-include it, the procedure is a little more complicated...

You will need to update to a new version of Z-Way. Since Z-Way has transitioned from Z-Wave.Me to Trident IoT, upgrading to the Trident IoT version cannot be be done from the web user interface. Run the following commands: cd /tmp wget https://github.com/tridentiot/z-way-builds/releases/download/v5....

Substituting "S0" for "S2" will not work.

Use this command to get the S0 key (called networkKey):

S2 keys are stored in the directory /opt/z-way-server/config/zddx in the file that ends in -DevicesData.xml. The file name begins with 8 hex digits that are unique to each network - these digits are the Z-Wave network ID (in hex). This command should print out the keys: grep '^ <data name="S2.*...

If you're familiar with linux, you can manually install Z-Way version 4.1.4 from the shell prompt as follows: cd /tmp/ && wget https://storage.z-wave.me/z-way-server/z-way-4.1.4_armhf.deb && sudo dpkg -i z-way-4.1.4_armhf.deb Note that Z-Wave.Me announced the business is closing/ceas...

My reply is off the original topic of bootloader issues, but may be helpful... My problem, unfortunately, is that I don't know Home Assistant or what the Zooz 800-series controllers are. And the Silabs documentation is very unclear for me. I also don't have time to familiarize myself. It would be gr...

@seattleneil: Where do you know, that the current bootloader is up-to-date? The response to remain at 7.42 was to avoid breaking something that's working. Yes, the version graph at the following link shows a newer bootloader and firmware version are available. https://service.z-wave.me/expertui/uzb...

Everything should work as before in v5.0.2. Nothing was removed from the Trident IoT version. @PoltoS Are you able to put a link to the full 5.0.2 version on https://storage.z-wave.me? Currently, the web site shows the following: Screenshot 2025-06-08 200659.png Should Z-Way users running version 4...

Your system is on the most recent bootloader, firmware and Z-Way version. It sounds like there's a problem with the Z-Way firmware update page offering you an invalid upgrade. Ignore the upgrade offer.
