Is possible to run the Phillips Hue lights without the bridge device?
I've been trying to search and see if the phillips hue bulbs can work without the hue bridge and just talk to it with a raspberry pi and a . Has anyone tried this yet?
Yes, it is possible.
You can manually pair the lamps with a LivingColors remote, a hue dimmer switch or a hue tap switch.

I have an Ubuntu 18.04 server on a laptop that has bluetooth adapter. I also have a led strip from China which also has a bluetooth adapter. I can control my led through an app on my phone.
Is there any way to successfully connect to the led strip with my linux laptop and control it?
If so, how could I know which code / key (or I don't know how this bluetooth control works, sorry) is assigned to a color? So basically, I don't know what command should I send to the strip.
Can anybody please write an example program for me?
I tried the rfcomm, bluetoothctl and bluetooth-sendto but they didn't work. :(
Hope we can solve my problem.
You'll need to reverse engineer your device :
with little research I found this

I just got an Azure Kinect and tried connecting it, but it does not enumerate in device manager or Azure Kinect Viewer. I have it plugged into USB 3.1 in a new Lenovo Y740 15", but the light is still blinking white on the Azure Kinect. I also went through the steps to reset the device, but the light continued to just blink white. Would anyone happen to have any suggestions?
You can find the meaning of the indicators here

Flashing white means that the camera does not have a data connection to the host PC. You mention you are using USB 3.1 (assume USB-C connector). Is the cable you are using a power+data capable or just power. Some USB-C cables are power only.
I had a quick opinion question regarding a Raspberry Pi/Python based home security system I'm working on. My end goal is to have magnetic door/window sensors being monitored by a Raspberry Pi 4 server. If a window or door is opened while the system is armed it will play an alarm sound to the connected speakers. I would then have Raspberry Pi Zero W powered keypad panels (with LCD screens and a 12 digit keypad) that would allow me to see whether the system is armed or disarmed and allow me to input the passcode to arm or disarm the system. The Raspberry Pi Zero W panels would connect to the Raspberry Pi 4 server over the network.
I already have a somewhat functional test system running in a single Python script with everything connected to the Raspberry Pi 4 (link below). However, I'm now at a point where I need to figure out how to tie in the Raspberry Pi Zero W keypad panels I would like to integrate over the network. My question for you all is how would you go about implementing the network connectivity portion of this? Should I use something like Node.js with some kind of database? Perhaps the socket module in Python for something low-level? Something else entirely?
I'm up for any and all suggestions for how to go about this. Please let me know if you have any questions. Thanks in advance!

If this was me, As you have the power of a full fat Pi 4, I would use a PHP web server on the "server" Pi that the other nodes POST to. This will give you the benefit of not having to deal with low level networking. You could also potentially add further devices or web services in the future with more integration opportunities.
You would then need to interface python to the PHP server however this could be done with a simple text file or alike.
I got a measuring instrument which can measure light intensity and this instrument can be connected to a PC via USB.
I now want to be able to read the values from the device via a Raspberry.
When the instrument is connected to the Pi, it shows up when entering 'lsusb' to the terminal and it is also listed under '/dev/usb' as hiddev1
But how can i actually grab the data from the device?
When i enter 'sudo cat /dev/usb/hiddev1' nothing happens.
Thanks in advance for your help
Try using HIDAPI, a cross-platform library for accessing Human Interface Devices.
I'm a newbie in this world.
I wanna build an application to remove some device.
Ex:
I wanna turn on or off lights and use my smartphone (Android) to do.
But, I don't know how to do? Can you show me all of steps?
Thank you so much!
Use a Raspberry Pi (runs linux).
You can have the RPi general purpose I/O lines to control, say, relays for lights etc. and then use the many Android apps to remotely control it.
