Lord-Grey Hello! Ive used ready to go image and flashed it on SD card, no any custom builds. As I've mentioned before - its version 2.0.14 right now, but I guess it was some of older version and I've applied few autoupdates later.
Anyway I can add these files to webconfig on GitHub for sure. The only reason to make it build in - CORS restrictions on API calls.
PR available here.
Indysingh maroonds Im on HyperBian image. v 2.0.14
Also I've checked Github for details and webconfig folder should be available somewhere.
Maybe Lord-Grey can help us to figure it out.
Hello! Sorry for the delay. I've switched to native Ambilight TV + DiYHUE Strip for extra line of lights last year and archived my Hyperion project.
Today I've booted my old Pi Zero with my setup and im ready to share my solution.
You need to create c subfolder inside hyperbian webconfig folder and upload 3 files first (I've used SFTP connection via my FTP client). Navigate to /home/hyperion/webconfig/.
Files attached in zip: color_correction.zip
Now you can navigate to your Hyperion ip like this https://192.168.1.233:8092/c with your phone. I have iPhone here so it will ask for camera permission.
Make sure it's https and 8092 port (check your web ui for exact ip and port). Otherwise camera will not work on unsecured website (in my tests it doesn't work on iOS 18 on http page)
You will see very simple UI where you need to point your camera to the tv screen on left half and projected led light on the wall on right side, follow guide lines on phone screen.
Click on INIT button to start the process. App will highlight current calibration mode automatically.
You need to prepare all colors slideshow on your TV.
Same steps for all colors (WHITE, RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW):
You will see the result immediately on every color adjustment. Most important ones is WHITE and RGB.
Check for accuracy indicator for extra information about your progress.
For now I can only attach my dev page screenshot of the app.
Let me known of your results here, share your color accuracy before and after. I've tested on v 2.0.14.
If you need any - I've attached color png files.
Thank you!
P.S: It's not hard to create dedicated webpage to communicate with it via WebRTC and QR codes to display exact colors on TV screen. So, no need to manually display images on your TV.
I've used my own solution with phone camera+hyperion API to adjust all colors (W, R, G, B, C, M, Y):
I've created PoC for my automatic color calibrator via iphone camera and it works good for my setup but i can't save settings via available API, so, i still need to put numbers and save them manually.
Here you can see default RED color (255,0,0) against adjusted via camera (255,22,2). Camera feed used to compare tv screen with wall color, no need to have 100% white balance/color match in this case.
Some progress with WHITE calibration. Full automation, just clicking on button after proper camera position.
Any options to save these adjustments via API?
Hello! Im trying to develop some addon for my Hyperian setup. My web app communicate with JSON API.
I've tested some methods and all works fine except this one: Adjustments
I have successful response but none of adjustments are saved.
My Payload:
{
command: "adjustment",
adjustment: {
gammaRed: 1,
gammaGreen: 1,
gammaBlue: 1,
white: [255,255,255],
red: [255,0,0],
green: [0,255,0],
blue: [0,0,255],
cyan: [128,255,255],
magenta: [255,0,255],
yellow: [255,255,0]
}
}and response:
{command: "adjustment", success: true, tan: 0}In web UI i still see old values after page refresh:
I've tried single adjustment and multiple ones as described in manual - no success.
Please advice what im doing wrong.
Thanks!
Thank you for your answer. Ive decided to recheck my led layout and found the issue. I have a gap of 1 led on connection point and ive missed something about it - gap counts as led in total leds count as well as in bottom leds count. Corner gap in your example helped a bit to better understand the layout settings. Now i have perfect match for led position and colors on screen.
Im confused about proper LED layout settings in Hyperion. Check my image for details.
Option #1:
Option #2:
Option #3:
Which one is correct in terms of Hyperion settings for vertical and horizontal leds count?
The problem is that on my setup I can't perfectly align leds to colors (position) on the screen. It's ok on right/top sides and start to shift on left and bottom slightly.
I've mounted my led strips like on #1/#2 pictures. For #3 I have a question — if Hyperion expect this layout, what about corner? Its missed?
It will be awesome to have profile or just brightness settings based on time. Daytime - 100% brightness, night - 50% for example. What you guys think about it?
Hello!
I'm technical guy but still can't get the point of few most important settings here and there. Like smoothing for example.
My feature request is about to have simple settings for ambilight setup, like Brightness, Saturation, Blur, Fade In/Out speed.
So, 5 sliders will do the job.
Hello! Im ok about fast color switching of LEDs to new color, but I don't like how quick they turning black, so, I want to get longer fade out effect. Is this possible? I'm still can't find useful explanation of Smoothing options here on forum unfortunately. As I understand it - it will help with high freq flashing from one color to another and back, so, its nothing about fadeout.
Another issue - single green leds on dark scenes. I've tried to crop 2 pixels on all sides and rise minimal Backlight threshold to 1-2% - it still not helping.
