SMLIGHT SLZB firmware update and all devices offline

Configuration Zigbee
1

Had an update today (v2.8.7) and now all devices offline. Never seen this before. Anyone resolve this or have this issue today?

2

Yes here is another thread, but no resolution yet. I am on v2.8.7 with no issues.

3

Where do I find the one to revert to? Is it the core/firmware or both?

You can access your coordinator via http://slzb-06 or it’s IP address

5

Am I updating the zigbee OTA? I can’t find where to downgrade that. Updating the Core firmware doesn’t work - says disconnected.

Yes you should be using this. You’ll need to provide additional info to address why it is showing disconnected

What specific SLZB device are you using?

Update: The firmware update caused it to change to ‘USB’ mode. Once I switched it to LAN it connected.

Change this, o think in the Setting Web Site fixed it?

UPDATE: It works!!!

Changing the setting resolved it.

Arrrggh - I wish I’d seen this post (and the fix) before I hit this too. I had the same experience and had to re-pair everything after rolling back to version 2.7.1. A quick summary of my process (there seem to be a few ways to do this) :-

1.) Go to SMLIGHT FIRMWARE UPDATER and select the SLBZ-06 section on the left and pane.
2.) Select firmware 2.7.1 from the available f/w selection.
3.) Connected my device to my PC via a USB-C to USB-C cable. I found that my PC didn’t see the SLBZ-06 in device manager so installed the drivers from https://www.silabs.com/documents/public/software and selected the “CP210x_Universal_Windows_Driver.zip” file. Under your COM ports in device manager the SLZB-06 should now be seen as a “Silicon Labs CP210x USB to UART Bridge”
4.) Flash the software onto the SLZB-06 by clicking “Flash v2.7.1”.
5.) Reconfigure the SLZB-06 and connect to the SLBZ-06 web page. From there it will ask what mode you want to use the device in. I used Zigbee co-ordinator and it downloads and installs the correct radio firmware for you.
6.) Ensure HA sees your SLBZ-06 as it did before.
7.) Re-pair devices.

Sorry, I only down-revved before seeing the fix so PLEASE DON’T DO THIS if not required. I plan on trying the update again tomorrow and changing the mode from USB to LAN. Much easier :slight_smile:
