litra-driver's Issues

Increase/Decrease brightness/color temperature

Great tool, thank you for your effort!

If you should be able to get the current state from the device as hinted on in #22, could you please also introduce commands to increase/decrease the brightness/color temperature?

Windows NotImplementedError

In windows getting NotImplementedError: is_kernel_driver_active after installing libusb. This Exception should be caught instead of AttributeError in the driver.

Different idProduct for the Litra Beam

Thank you for making this software. I just got a Litra Beam which is very similar to the Litra Glow. So I am optimistic that this software will work for the Litra Beam as well. The output of the lsusb command shows the following for the Litra Beam

Bus 001 Device 113: ID 046d:c901 Logitech, Inc. Litra Beam

As far as I can tell, the only change that should be necessary is that the udev rule should mention ATTR{idProduct}=="c901" instead of "c900". However, I also noticed that the c900 is hard coded as the PRODUCT_ID in src/llgd/lib/llgd_lib.py. Is there a way to specify the product id via the command line or a config file, so that this will work with the Litra Beam too?

Thanks in advance.

Limited brightness range using hidapi

I've set up my Litra Beam control through hidapi. However, I've found the brightness control range to not be as wide as with using G-Hub.

With hidapi, the maximum brightness value of 250/ 0xfa translates to only about 65% of the max brightness capability of the litra beam as configurable in G-Hub. Any chance there is more range for setting a higher brighness using hidapi?

Deleting a Profile

I delete profiles, and after I restart the app, or open it again, after closing it, the deleted profiles come back.

Unable to start lcui, after perform a quick install.

I ran thru the Quick start process and ran into the following error:

[jb@thehat ~]$ lcui

Tried to do a:

pip install tk

Then tried to run lcui and got the following error:

Any thoughts?

multiple Litras?

I would like this to work with multiple Litras. I was able to tweak the code to get it to work for my purposes. I'll open a PR...

Reading state from device

Shouldn't there be a way of reading the current state off the device?

libusb error in windows

Windows gives a no backend error when attempting to access libusb. Got past this by downloading libusb-win32 from source forge and copying bin/amd64/libusb0.* to c:\Windows\system32. Next error is:

Get tools working on mac without sudo

Hi,

Firstly thanks for this. I was able to control my light via command line on mac, but it needs to run via sudo due to the usb libs used currently. I'm able to use the codes you've discovered to turn on/off the light via https://github.com/todbot/hidapitester.

Light On

hidapitester --vidpid 046D/C900 --open --length 20 --send-output 0x11,0xff,0x04,0x1c,0x01

Light Off

hidapitester --vidpid 046D/C900 --open --length 20 --send-output 0x11,0xff,0x04,0x1c

This works without sudo. As far as I can tell udev roles don't exists on mac.

I understand your project is written in python and the other referenced project is written in C. I wanted to post this question here incase anyone else found it helpful.

Script name `lc` conflicts with `/usr/bin/lc` in `mono-devel` package

On Debian and Ubuntu systems, the lc program already exist in the archive and is the Mono License Compiler:

$ apt-file search -F /usr/bin/lc
mono-devel: /usr/bin/lc

Maybe the script could be renamed to llgd-cli which is a less ambiguous name with no conflicts. This would allow the program to be packaged on Debian/Ubuntu systems.

"ValueError: Device not found" on Windows

Maybe Windows isn't supported, but I'm trying to find a relatively simple solution for using my streamdeck to control the Litra Glow, without getting into all the hid stuff myself. I love the simplicity of this, but unfortunately it's not working "out of the box" for me. I already had python and pip installed, so I updated pip, installed litra-driver and tried to run it. The UI comes up, but when I select the on button or when I try the lc on command it fails and says "ValueError: Device not found" Here's the complete output:

C:\Users\Jeff>lc on Traceback (most recent call last): File "c:\users\jeff\appdata\local\programs\python\python39\lib\runpy.py", line 197, in _run_module_as_main return _run_code(code, main_globals, None, File "c:\users\jeff\appdata\local\programs\python\python39\lib\runpy.py", line 87, in _run_code exec(code, run_globals) File "C:\Users\Jeff\AppData\Local\Programs\Python\Python39\Scripts\lc.exe\__main__.py", line 7, in <module> File "c:\users\jeff\appdata\local\programs\python\python39\lib\site-packages\llgd\cli\cli.py", line 77, in main fire.Fire({ File "c:\users\jeff\appdata\local\programs\python\python39\lib\site-packages\fire\core.py", line 141, in Fire component_trace = _Fire(component, args, parsed_flag_args, context, name) File "c:\users\jeff\appdata\local\programs\python\python39\lib\site-packages\fire\core.py", line 466, in _Fire component, remaining_args = _CallAndUpdateTrace( File "c:\users\jeff\appdata\local\programs\python\python39\lib\site-packages\fire\core.py", line 681, in _CallAndUpdateTrace component = fn(*varargs, **kwargs) File "c:\users\jeff\appdata\local\programs\python\python39\lib\site-packages\llgd\cli\cli.py", line 28, in on light_on() File "c:\users\jeff\appdata\local\programs\python\python39\lib\site-packages\llgd\lib\llgd_lib.py", line 68, in light_on dev, reattach = setup() File "c:\users\jeff\appdata\local\programs\python\python39\lib\site-packages\llgd\lib\llgd_lib.py", line 34, in setup raise ValueError('Device not found') ValueError: Device not found

I also ran pip install libusb since I saw it referenced in previous issues. Oh, and I made sure GHub isn't running, and unplugged/replugged already. Got the same result in commandline and powershell, haven't tried WSL yet. Sorry if I'm just making a dumb mistake here, I'm not a coder, but I do design and support software for a living, so I can usually follow developer directions.

support for G Litra Beam LX??

Hey, as the title says do you plan to add support for G Litra Beam LX or is it already supported?
