zigbee | A zigbee API for the Rust programming language

I have bought a xiaomi ZigBee smart plug and paired it with my Mi hub. I want the plug to control my router. But when I set on/off schedules , it will turn off the router but it wont turn it on after the scheduled time. Can it be solved?

i got a similar problem like this one:

How to convert CIE color space into RGB or HEX color code in PHP

how to convert xy color to sRGB? I can't get the formular working xyY. What should i enter for Y?

i got an ikea light bulb which gives me a XY color value in the (CIE 1931 colorspace) I would like to convert it into RGB,(sRGB) or HEX.

The Phosconn app is sending the following xy values when setting the colors by full brighness and saturation.

We are working on a project with Nessus Attack Scripting Language ( NASL ) and we would like to run a programm written in C++. I want to ask, is it even possible to run another Script with NASL?

So we would like to run the NASL script, which runs another C++ programm, which works with Zigbee to mqtt.

I have my own application. This application use the zigbee2mqtt service running on the server.

I want to add homeassistant on the same server.

The server is a Raspberry with a zigbee USB stick connected.

However, it seems that using both in the same time doesn't work.

Either it works for my application, either it works for home assistant.

Someone has an idea how to deal with it ? Does I need to buy an other zigbee USB stick (one for my own application, and one for Home assistant ?)

Thanks

we ran into a weird issue when receiving ZigBee packets on Windows. We are currently sending packets from a drone every 0.8s, but on Windows we are receiving only every ~5s. We aren't loosing packets, as the received packet ID's increment correctly. The strange thing is, when using an Ubuntu VM on the same computer it works perfectly, and we receive at about ~0.8s.

We are using Digi-Xbee 1.4 and a "Xbee SMT Grove Dev Board" connected by USB for both sending and receiving.

Here is the code were using to receive on both Windows and Ubuntu:

I have a temperature, humidity and pressure sensor working over the LoRaWAN , I can get the read with the phone by NFC.

Also, I have some Arduino projects working with esp32 and RFM9X(Lora) boards to exchange data between the radio modules.

I want to sniff the LoraWAN packages that exchange between radio boards or between the sensor and another device

How I can do that by Wireshark??

I already have cc2531usb dongle I am using it for ZigBee packets , can i use it for Lora and how?

I would like to decrypt Zigbee paquets from a Xiaomi Aqara switch. Here is the raw encrypted frame I sniffed on a network:

Lets say I have a robot, with a raspberry pi, or a jetson, running ROS. And I want to see the sensor readings, or something on RVIZ, on my laptop. Or maybe control the robot using a wired Xbox controller connected to my laptop... Is there anyway I can write a node on my laptop that can connect to the roscore of the robot (rpi/jetson) over the lan network, or a zigbee module or something?

Or do I have to create another instance of roscore on my laptop, and make them talk to each other through the zigbee module/lan? That would be very tedious... Please don't tell me that it's the only option.

EDIT: The part about connecting the robot and the computer using lan has been explained... I'd really appreciate it if somebody could now tell me how to connect it to the robot's roscore using RF modules

Context:

I am working on an embedded openwrt on a retry system for http request and certificate peremption checking.

We don't trust our web server and want to make retry GET HTTP on file every days until it's downloaded.

We also want to download files at precise hours.

During regular times, the program is:

• managing the state of Leds and network state
• receive messages from message queues to execute web request and network administration
• It monitors 2 other process one bluetooth and one Zigbee that may crash.
• By the time we go in prod it will probably do other things.

Problematic:

I want to program in C a signal every day to get asynchronous events. So i basically want crontab without crontabs.

The signal I want to use is the ones used in IPC (I don't know other way to create asynchronous behaviours on linux) : https://www.man7.org/linux/man-pages/man7/signal.7.html

I know how to use crontab but i would prefer to do everything in C as it would make my architecture simpler for my coworkers who don't use linux.

• As far as i know crontab don't have a C api.

• I used timers in my code but they don't seem to fit this usage: https://man7.org/linux/man-pages/man2/timer_create.2.html It should be doable to request the date and time from the system and create a timer to fire at the desired hour everyday but I thought there might be an already made solutions on Linux. Something like eventHour(hour, signal, handler).

• I don't have systemd https://linuxconfig.org/how-to-schedule-tasks-with-systemd-timers-in-linux

Question: What is the proper way in C on Linux to get dayly/periodic signal ?

Many thanks,
