Hello,
I have implemented everything so far and it runs flawlessly. Only I do not know where to open the Hue app. Where and what do I have to do?
Thanks in advance!

Hey,
I had this running on raspberryos for more than a year. Used it almost daily. I wanted to bump it to the latest version and I got this error. I started completely from scratch with a clean ubuntu server install on the rpi4. Same hardware that worked before.
After adding my user to the video group I was finally getting video, but not in the script.
I see the Input on videotest.py (installed gnome and used xforwarding...) but its showing the warning. Harmonize script itself wont work.

Hi,

I cannot seem to connect to my hue hub, I get the below error:

pi@raspberrypi:~/HarmonizeProject $ python3 ./harmonize.py
I will use the bridge at 192.168.5.24
Hue bridge not found. Mission failed, better luck next time

originally my hue hub was in 192.168.4.206, it’s all on the same network but I switched it and cleared the pi cache. I have also done it on a brand new install.

I noticed a closed issue where someone suggests deleting the config.json file but I do not have the file.

Any ideas would be appreciated.

Hey not sure if this is an issue that can be resolved with the program or if it’s a HW issue but my Hue lights flicker even when the scene on the tv isn’t changing. Please see attached video.

Opened by @Bboy486 on August 13th

This is two issues in one. One is fixed.

1- The project sees the hue hub and when I press the button (or hold it down) I get an error that it has timed out have a nice day (something like that). I had to
cd harmonizeproject
and install from the folder.

2- After I did that I was able to add my hub. But I did receive the error below.
Success! I generated a username and client key to access the bridge's Entertainment API!

Following up from #7 (comment)

In the instructions, there are some missing steps.
change cd harmonizeproject to cd HarmonizeProject
after sudo ./setup.sh you will need to give executable rights to ./harmonize.py
run - ls -la
If there is an X missing from harmonize.py then run the following:
sudo chmod +x harmonize.py

If you run ls -la, you'll see the file is now executable

now run sudo ./harmonize.py

I was looking at the trace and noticed a lot of corrupt jpeg data

LAstly, when I try to re-run the .py I get this error

sudo ./harmonize.py
I will use the bridge at 192.168.1.7

"Hello, I am trying to install this on my PI4 using Rasbian Buster Lite OS but it seems to encounter a lot of missing dependencies. What OS should I be using? I already purchased a HDMI - USB capture card but have been having difficulties getting this thing to run. Any help would be appreciated. Thanks"

Wanted to know if there's an option or a parameter one can tweak to increase the intensity of light through the script. It works great ofcourse but I've noticed that the lights are dimmer compared to the app version of hue sync. Apologies if this is something obvious that I'm missing.

Example image links in the README are broken with a 'Cannot proxy the given URL' message

I always get this error,
Script connects successfully, turns Hue Gradient dark and then shows colors of picture / first frame.

python3 harmonize.py -g 2 -i a.b.c.d -f bigbuckbunny.mp4

Then this shows up:

I have attempted both paths you list on a Raspberry Pi running Ubuntu 20.04 and neither build path produces a harmonize.py that starts.

Can you confirm that both install processes have been tested recently? I'm trying to understand why I'm having such trouble, given that you seem to have very clear instructions (they were easy to follow).

There are a couple packages that it says it can't find (when running your install script) so I don't know if they've been recently retired/changed or not. That's why I want to confirm that the install approaches have been tried recently from a clean install of the OS (that's where I started from)

Thanks!

Hey great script.

i use it on a raspberry 3b with a LogiLink Audio und Video Grabber USB 2.0

my questions is there a way to input more code for fine tuning to the script like values for:

• cropping
• saturation
• contrast
• brightness

thx

After it finds the bridge it only gives a few seconds to push the button (it never asks me to though - not sure if it is supposed to), but then it just says the bridge isn't found.

Any help would be appreciated.

Hello there. Yesterday I started setting up the harmonize project in my house. I bought everything I needed and after many hours of work I managed to make it work, I am very happy with the result. But the fact that I have to manually launch the harmonize.py file bothers me a lot as I have the whole house automated. So I installed supervised home assistant in a container on the raspberry itself and am trying in vain to integrate it. I tried with shell command but it constantly gives me error, probably because harmonize is in the root of the raspberry while home assistant is in the container. Is there any way to integrate and make these two software work together?

"Very cool and inspiring project! Always wanted one of these, but off-the-shelf prices are ridiculous..

First thing that immediately came to mind when I saw this: would this work with an HDMI-to-CSI adapter, such as eg https://www.amazon.com/dp/B0899L6ZXZ/ref=cm_sw_r_cp_apa_i_edwkFbJ7V4HT2 ?

Tl;dr: with GPU-accelerated frame processing, I'm hoping this could run even on a Zero..! :)

Other than potentially reducing cost a little bit (CSI adapter vs USB capture), the main advantage is that video downscaling (to compute average color intensities around border) could be offloaded to Pi's GPU (eg, see picamera Python module docs on "advanced configurations" -- GPU can even compute motion vector data quite efficiently, let alone just do pixel averaging). This could possibly allow the use of a smaller Pi, perhaps even a Zero, which would then really reduce cost.

The converters' frame rate is relatively low ("up to" 25fps), but I don't believe this matters here.

The only real catch is that these converters don't do HDCP. But, perhaps, if there is a reasonably priced splitter that can also do HDCP stripping on lower-res port..

I just wish my TV could do full HDMI pass-through (not just ARC to receiver but, eg, for chaining a second monitor), or my receiver could route to both zone's HDMI outputs simultaneously (rather than switching video and splitting just audio), but both of these features seem to be exceedingly rare.. sigh!

Finally, apologies in advance if using an issue for general commenting was inappropriate (feel free to close/delete, of so) -- but just my 2c. I'll probably take this up myself when (if?) I find some time."

i have an odroid lying around. can i use it instead of raspberry pi
