Hyperion 2.2.0

🚀 Hyperion 2.2.0 Release

Hyperion 2.2.0 has arrived, bringing a significant leap in performance and stability. This release focuses on a massive core refactor designed to slash memory usage and optimize resource consumption. Alongside crucial security updates for Hue Bridge users and expanded RGBW support for WLED and e1.31 devices, we’ve introduced a completely rewritten Windows DDA grabber for better stability and a new DRM/KMS grabber tailored for Raspberry Pi OS users (Kodi grabbing does currently not work). These architectural overhauls ensure smoother, more efficient ambient lighting across all platforms while resolving long-standing resource bottlenecks.

📥 Get Started & Download

You can download the latest executables via our official repositories for Debian, Ubuntu, and Fedora, or grab the release files directly from GitHub.

• For most users: Please visit our Getting Started Overview for instructions on installing or updating the software.

• For Raspberry Pi users: We recommend HyperBian—a ready-to-use SD card image based on "Raspberry Pi OS Lite" with Hyperion pre-installed. Follow the HyperBian Step-by-Step Guide to get up and running quickly.

Hyperion 2.1.1

🌿 Hyperion goes green!

Resource consumption during builds has been drastically reduced behind the scenes by streamlining processes and encouraging reuse.

This release also involves significant refactoring of the core elements of the platform and the API.
This version comes with many bug fixes and a number of long-awaited new features and improvements.

You can download the executables from GitHub or even better via our official repositories for Debian, Ubuntu and Fedora.

Installation and update instructions can be found on the comprehensive instructions page. Just select the method you would like to use.

Note

This release supersedes versions 2.1 and 2.1.0, which had some critical issues. Many thanks to those who shared their findings, and we apologise for any inconvenience caused.

Tip

In case your USB grabber produces a black output it is likely that its hardware controls are set to zero.
To get this corrected:

1. Switch to 'Expert" settings level
2. Go to the "Capturing Hardware" Screen
3. Click the "Default hardware controls" button (the "Hardware xxx control" values should change)
4. Save the updated settings

Change details

Hyperion's February release provides you with the latest updates and fixes.
Key new features: You can now stream to a dedicated WLED segment, put Hyperion in Suspend or Idle mode or apply dominant color rather than mean color processing.

Many thanks to @EliteScientist who contributed with an audio grabber which works as the other existing grabbers,
i.e. you can use the input feeding multiple instances in parallel or forward the input.

Added

• Audio Grabber to add audio visualization support for both Windows and Linux.

Hyperion 2.0.0-alpha.11

The release is primarily fixing issues introduced with alpha 10, but covering other findings too.
Thanks to everybody highlighting real problem areas, as well as to those proactively providing fixes for integration via pull requests.
Besides bug fixing, you will find some smaller enhancements which make everybody’s life easier.

The fact that WS281x devices must run under root caused many headaches before in getting them running.
We did not weaken security, but provide you with an easy to use script to switch the user-id of hyperion going forward. Furthermore, device configuration is blocked, if the environment does not allow it.

Added:

• Script to change the user Hyperion is executed with.
  To run Hyperion with root privileges (e.g. for WS281x) execute
  sudo updateHyperionUser -u root

• Gif effects can source Gifs via URLs in addition to local files as input

• System info screen: Added used config path and "is run under root/admin"

• LED-Device enhancements

  • WS281x: Ensure that a device cannot be configured via the UI when Hyperion is not run with root privileges
  • Nanoleaf: Support discovering additional Nanoleaf devices, e.g. Shapes
  • Nanoleaf: Ability to restore state when Hyperion stops streaming
    
    Note: In case previous state was a dynamic/temporary effect, the state cannot be restored
  • Nanoleaf: New Feature: allow to overwrite brightness by Hyperion

Changed:

• The Systemd/Upstart/System-V-Init service registers Hyperion under the name hyperion instead of hyperiond, as this has caused confusion among users in the past.
• WLED and UDP-Raw: Limit maximum LEDs number to 490
• WS281x: Update DMA default as per rpi_ws281x recommendation
• Smoothing is paused when no input source is available (to save resources)
• Disable LED update streaming, if LED updates are not required, Sync. Video-Streaming between Layout and Simulation
• Load configuration of last instance used when loading the UI page, Streamline API requests to avoid unnecessary invocations (#1311)
• BobLight: Priorities are not limited any longer. BobLight can feed Priorities [2-253], default is still 128 (#1269)
• Amlogic grabber: Limit grabber to 30fps during discovery
• Amlogic grabber: Continuous image feed even when paused (to not have LEDs switched off), plus no delay when pausing/unpausing

Fixed:

• Fixed that Smoothing with "Continuous Updates" disabled does not provides LED updates (#1068, #1240)

• Fixed Issue Blinking / flickering cursor with QT screen capture on Windows (#1328)

• Fixed Colour effect priority is not deleted when Colorpicker is open (double click on delete is required)

• Fixed reuse local SSDP address (#1324)

• Exclude FB Grabber on Amlogic platform, as FB is included in Amlogic Grabber

• Escape XSS payload to avoid execution (#1292)

• Include libqt5sql5-sqlite packaging dependency

• Fixed embedded Python location (#1109)

• LED-Devices

  • Fixed Philips Hue wizard (#1276)
  • Fixed AtmoOrb wizard
  • Fixed that Lightpack device does not core when lack of permissions error (LIBUSB_ERROR_ACCESS)
  • Fixed Atmo/Karate LED count constraint handling
  • Fixed Hue, Disable LED general options (HW Led count & RGB Byte order) as calculated
  • Fixed SPI, Tpm2.Net - Memory issues
  • Fixed: Nanoleaf does not turn on
  • Fixed LED layout - Additional parameters for classic layout were not saved (#1314)
  • Fixed Network LED-Device UI: Trigger getProperties for the configured host, when no hosts were discovered

Removed:

• Smoothing: Removed "Continuous Updates" flag as it is obsolete.
  In case an LED-device requires continuous updates, use the LED-Device's "Rewrite Time" parameter.
