The SLZB-06 core firmware update will not be completed.

The problem

Since January 20, 2024, an update from the installed version v2.6.8.dev25 to the latest version v2.7.0 is available. The update was initiated via the Home Assistant user interface. At first nothing happens, but when I return to the update interface, it is displayed that an update is currently being installed. But even after 2 days the update is not completed. After restarting the integration, the update from v2.6.8.dev25 to v2.7.0 is available again.

What version of Home Assistant Core has the issue?

core-2025.1.1

What was the last working version of Home Assistant Core?

My new device reported:

SLZB-06M Core firmware Update available
Installed version: v2.3.6.plus
Latest version: v2.7.1

Clicked install, got some download/install timer graphics, then nothing. Said update available again.

Clicking update again gives "Failed to perform the action update/install. Update installation already in progress for update.slzb_06m_core_firmware".

But this persists, update never completes.

Thansk for the report, I will need to look into this. Upgrade to 2.7.0 worked for me. However I can see this error in your logs:

    )

It is possible that just the notification of upgrade complete is not working here. If you reboot HA or check SLZB UI after failed firmware update, can you confirm it still on old version or new version?

[brucetm]

You are right, the update does seem to have actually worked, I logged into the gateway device web console and it shows the expected updated rev. Only Home Assistant fails to get the status updated. Reboot etc. did not change that.

[brucetm]

Scratch that: after another reboot of HA (or perhaps it was rather just some periodic long running timeout?) HA now also knows that the update is no longer needed.

[schoppfe]

I wasn't even able to update via the web UI of the device itself. It couldn't find the firmware. Unfortunately, I forgot to write down the error code. At the end I had to download it manually

[Eddio56]

I have the same issue. Then I tried to update from 2.6.8 to 2.7.0.or 2.7.1 i get error message Req err, code: -1

Do you have authentication enabled on your SLZB devices? If so this will likely be the same as:
#135870 (comment)

[Eddio56]

Thanks for assistance. No, authentication is disabled. All previous updates were successfully done without authentication. It’s something new? And if I enable authentication , what default password? I see user admin.

[tl-sl]

@Eddio56 no nothing has changed with authentication, but that other issue only occurs if you have authentication enabled.

I have not been able to reproduce this specific error yet. There is a chance however, that the other fix will also resolve these errors here with SSE events. It is those events that provide the feedback for update progress and update completed.

[Eddio56]

@tl-sl you mean, we must to wait for next firmware, say, 2.7.2, to fix this bug?

[tl-sl]

The other fix should be in the next HA update, maybe 2025.01 if there is another one, otherwise 2025.02

[Eddio56]

@tl-sl I think my problem is bug in firmware of SLZB-6b, not in HA. I tried update device directly from it web interface, not through HA.

In that case you should contact SMLIGHT support directly. This issue tracker is for Home Assistant related issues.
