Ubisys OTA Appears To Fail But Actually Succeeds

by ADMIN 49 views

Introduction

In the world of smart home devices, Over-The-Air (OTA) updates are a crucial aspect of ensuring that devices remain secure and up-to-date with the latest features. However, sometimes these updates can appear to fail, leaving users wondering what went wrong. In this article, we'll explore a specific case where Ubisys devices seem to fail during OTA updates, but ultimately succeed.

The Issue

When attempting to update a Ubisys device using Home Assistant (HA), users may encounter error messages indicating that the update failed. These error messages can be misleading, suggesting that the update process has stalled or encountered an issue. However, as we'll discuss later, this is not necessarily the case.

Error Messages

The error messages associated with this issue can be quite alarming, with some users reporting the following:

2025-03-11 12:30:14.067 INFO (MainThread) [zigpy.device] [0xdf4b] OTA upgrade progress: (256168 / 256200): 99.9875%

The above exception was the direct cause of the following exception:

    raise HomeAssistantError(exc) from exc
homeassistant.exceptions.HomeAssistantError: Update was not successful: <Status.FAILURE: 1>

The Reality

Despite the error messages, the Ubisys device is actually installing the new image after it has been transmitted. This means that the update process is not failing, but rather, the logs and UI are not accurately reflecting the progress.

The Explanation

This issue is likely due to a cosmetic problem, where the device is not responding to the upgrade call correctly. However, the device is still able to install the new image, which is the primary goal of the update process.

The Solution

In this case, the solution is not to try and troubleshoot the issue, but rather to wait for a short period of time. After some minutes, HA will likely find the new version on the device and show the status correctly. This is because there is a series of upgrades to be done, and the device is simply taking its time to complete the process.

Conclusion

In conclusion, the Ubisys OTA update issue appears to be a cosmetic problem, where the device is not responding to the upgrade call correctly. However, the device is still able to install the new image, which is the primary goal of the update process. By waiting for a short period of time, users can ensure that the update process is completed successfully, and the device is up-to-date with the latest features.

Recommendations

  • If you encounter error messages during the OTA update process, do not panic. Instead, wait for a short period of time to see if the issue resolves itself.
  • Make sure that your device is properly connected to the network and that there are no issues with the power supply.
  • If the issue persists, try restarting the device or the HA system to see if that resolves the issue.

Future Development

In the future, it would be beneficial for the developers of HA and Ubisys devices to work together to resolve this issue. This could involve improving the logging and UI to accurately reflect the progress of the update process, or implementing additional checks to ensure that the device is responding correctly to the upgrade call.
