Audioserver Update: Important info for users of Huawei routers

1st February 2022 in Technology
The latest firmware update to Audioserver is now available to download. This update will not be initiated automatically due to known issues with Huawei routers.

Version of the Audioserver firmware is now available to download. This update will be made available from the Loxone app and web interface from 7 February 2022. We recommend this update for all users. This latest update includes a host of fixes and improvements to the powerful Audioserver. To view the complete list of what is included, you can refer to the changelog at the bottom of this blog.

For those who have a Huawei router in the installation: an update to the router itself may be necessary before installing the Audioserver update. If you’re not using a Huawei router, you can install the update straightway to benefit from the improved functionality.

Important information for those with Huawei routers

At the beginning of December, we released an Audioserver update ( However, due to feedback about network failures in connection with certain Huawei routers, we deactivated the automatic update.
We were able to trace the problem back to the use of the PTP network protocol (Precision Time Protocol), which, due to a bug in the Huawei router firmware, leads to a reboot loop on certain models and thus to a network failure.

The following Huawei routers are affected:

  • B525
  • B528
  • B529
  • B535
  • B818

We are in contact with Huawei and the distributing network providers and have been able to work out a solution to the problem: If you are using one of these Huawei routers in your installation, please check the router’s contact page to see if a new update is available. If no update is available, please contact Huawei’s customer service or your network operator.

You can reach Huawei’s support team through the following methods:

Please give them your device’s serial number and firmware version number and ask for an update to the latest firmware version. A software update will then be made available to you for download, which will solve the problem. Afterwards, you can also install the Audioserver update without any issues.
