Product Usage Instructions

Updating Firmware
To update the firmware, follow these steps

1. Access the web interface of the device.
2. Locate the firmware update section.
3. Upload the new firmware file.
4. Initiate the update process.
5. Wait for the update to complete and reboot the device.

7.16.5.31 – March 3, 2025

• Firmware updates via hawkBit
  • Firmware can now be downloaded from the hawkBit update server (requires internet access). Once downloaded, firmware can be distributed and activated automatically to keep your network up to date. By default, distribution and activation remain manual, but you can configure an update time window for automatic processes.
•  Set up factory-default devices.
  • For networks with one or more factory-default devices, the newly added setup wizard can simplify the creation of new networks or the extension of existing ones.
• Web interface
  • The firmware update page and security pages have been redesigned for improved usability and easier navigation.
  • The web interface now supports multiple sessions, allowing users to stay logged in without needing to re-authenticate frequently.
• Miscellaneous
  • Added support for ECC cryptographic keys, enhancing performance and security.
  • Improved and simplified text across several pages for better clarity and user experience.

7.16.4.29 – November 27, 2024

• Network Manager
  • Update the firmware across your entire MultiNode network via the web interface of the master node.
  •  When new nodes are added to the network, the network administrator can approve these nodes to receive the admin password from the master node’s web interface. You can also set up auto-approvals so that new nodes with matching network credentials but factory default admin passwords automatically receive the admin password from the master node.
• Duplicate master node prevention
  • Duplicate master node detection is now configurable to repeat on reboots, and the detection time has been drastically reduced to a few seconds.
• Enhanced security
  • Users can now upload their certificates for TLS communication with the device. Each device generates its certificate using the default node name as the ID, enhancing network security.
  •  Various general improvements and bug fixes have been made to strengthen security.
• Web interface
  • Reworked the network overview table to be clearer.
  • Simplified the interface by combining warning banners and making node-specific and network-wide operations easier to distinguish.
• Miscellaneous
  • Fixed a bug that caused changes to the names of regular nodes to not persist reliably.

7.16.3.27 – August 15, 2024

• Network Manager
  • Easily manage network credentials, admin passwords, and web interface passwords across all nodes in the MultiNode network using the Network Manager on the web interface. The Network Manager is available only on the master node’s web interface.
• Duplicate master node prevention
  • Automatically detect if a master node with the same network credentials exists before assigning another master node, ensuring a smooth setup.
  • If you are upgrading from an earlier firmware, see the migration guide for 7.16.3.27.
• Update the default hostname.
  • The hostname and device name are now devolo-XXXXX (XXXXX are the last five digits of the serial number), replacing the previous devolo-XXX format.
• Enhanced security
• • Switched to TLS for the web interface for stronger security.
  • Display prominent warnings about security risks.
  • Enforced policies for secure passwords, network names, and node names:
  • MultiNode network name: 1-32 characters
  •  Only printable characters are allowed
  • MultiNode network password: 8-12 characters
  • Only printable characters are allowed
  • Node name: 1-16 characters
  • no restrictions
  • Admin password: Min. 1 character
  •  no restrictions
  • Web interface password: Min. 1 character
  • no restrictions
• Web interface
  • Minor improvements to the web interface.
  • Improved the network overview table.

7.16.2.25 – March 21, 2024

Note: This firmware version is provided for you to test the firmware update feature on your current network. After testing, please update the firmware.

Migration Guide

7.16.3.27 – August 15, 2024

• Before updating to 7.16.3.27, if you have used the web interface to set the role of the master node then the duplicate master node detection will be turned on after the firmware update.
• If nearby master nodes have the same network name, password, and seed, your intended master node might stay a regular node instead of becoming a master.
• To resolve this issue, modify one of the networks to use a different MultiNode network seed before rebooting your intended master node.
• The intended master node will now take on the role of the master node after a 30s detection period.

Frequently Asked Questions

Q: What should I do if my intended master node does not switch roles after updating?
A: If nearby master nodes have the same network name, password, and seed, your intended master node might stay a regular node. To resolve this, modify one of the networks to use a different MultiNode network seed before rebooting.
