Release Date 06.08.2026
New features and changes
powerIO Orbit: The web interface consistently uses the term powerIO Orbit instead of powerIO Portal.
Current Version - Bootloader
With Bootloader < 0.9, rare startup problems may occur after updates; turning it off and on again fixes this, and the restart can take a few minutes. The bootloader file can be installed independently of the firmware.
0.9 - Bootloader Download
Release Date 08.09.2025
Bug fixes and improvements
With Bootloader versions < 0.9, in rare cases after a firmware update the system may fail to start. If this happens, it must be powered off and on again. This startup can take a few minutes, as the update is performed again here. With this version, this error is fixed. The bootloader file can be installed independently of the firmware.
