Add a file for device status to datadir

Can you add a file that shows current status of the device - is it connected to usb or not, and maybe some other statuses that this device supports (mode? calibration period? malfunctioning?).

magic_table & decode_buf

Пытаюсь повторить процедуру на java (usb4java), но никак не удается получить правильные данные на выходе. Magic_table всегда разная (так должно быть?), result[4] тоже всегда разная (и не 0x0d), checksum (result[3]) тоже не сходится.
Подскажите пожалуйста, где можно узнать подробности такого странного кодирования данных, включая magic_table, Htemp99e и пр.
Где-то есть описание, либо был жесткий reverse engineering?
Спасибо.

Привет. Установил из brew всё необходимое, компиляция прошла успешно. Но при запуске вижу

Было бы полезно сигналить себе из crontab.
команда ./co2mond/co2mond | grep CntR | head -n 1 у меня почему-то не сработала...

cmake mac os None of the required 'hidapi-libusb;hidapi'

Не собирается на macOS 10.13.6.
При этом вот это видел, и вот так делал:
brew install libusb
brew install hidapi
brew install pkg-config

Give ability to list USB devices

The option -f has wrong examples in the help. The values that -f accepts depend on hidapi's internals.

The list of devices can be obtained by hid_enumerate.

Выход из hibernate

После выхода из hibernate получаю многократно повторяющееся сообщение в лог от ядра, пока не переткну девайс:

usb 4-1.4: usbfs: process 326 (monitor_loop) did not claim interface 0 before use

Пре пететыке у меня co2mond перезапускается автоматически — через правила udev и systemd-сервис.

Images description

Из названия файла я понял что:
graph-co2-1h.png - часовой график СО2
graph-temp-1h.png - часовой график температуры

Можете пояснить суть картинок graph-6d-1h.png и graph-56-1h.png ?

Why does this only run as root?

I'll include further details if necessary, but TL;DR it only works with root privileges. Why and how do I fix this?

Unexpected data from device (data[4] = fb, want 0x0d)

It seems there is new revision of ZGm053U hardware with new protocol, bought at dadget.ru. Doesn't works with apps from dadget.ru, but works with latest windows software from http://www.zyaura.com/

...

Does anyone have the same problems? Is there any chance to implement new protocol?

Wrong libco2mon.so install path

On x86_64 system libco2mon.so installed into /usr/lib instead of /usr/lib64.
Cmake should catch -DLIB_INSTALL_DIR directive for proper lib install path.

Arm compilation

Hi, so in default PKGBUILD arch=('i686' 'x86_64'), but i wanted to use it on raspberry pi archlinux arm os.
So i

1. changed arch=('i686' 'x86_64' 'armv7h') in PKGBUILD
2. install clang (cmake print some error with gcc)
3. CC=/usr/bin/clang CXX=/usr/bin/clang++ makepkg -si (rm -rf src/co2mon/build/ if you mess up with command on first try)

There will be a lot of errors in the process, for example about clang: warning: argument unused during compilation: '-fstack-clash-protection'
but in the end it works ¯\_(ツ)_/¯
hope this helps someone)

Unversioned libco2mon.so

Please start versioning of libco2mon.so.
For example, it is need by Fedora https://fedoraproject.org/wiki/Packaging:Guidelines#Downstream_.so_name_versioning

Library name must be in form libco2mon.so. or libco2mon-.so

Почему в README нет ссылки на co2meter.com?

Вот это похоже оригинальный девайс - http://www.co2meter.com/collections/fixed-wall-mount/products/co2mini-co2-indoor-air-quality-monitor

-P option crashes when run from a systemd service

Logs looked like this:

Oct 13 19:15:29 hostname systemd[1]: Started Polling daemon for masterkit co2monitor.
Oct 13 19:15:29 hostname co2mond[31973]: co2mond: signal(SIGPIPE, SIG_IGN): Success
Oct 13 19:15:29 hostname systemd[1]: co2mon.service: Main process exited, code=exited, status=1/FAILURE
Oct 13 19:15:29 hostname systemd[1]: co2mon.service: Failed with result 'exit-code'.

The same command was working outside of systemd and it took me a while to figure out that it wasn't a resource authorization issue.

It was failing at co2mond/src/main.c:692.

Adding IgnoreSIGPIPE=no to the service definition avoids the problem.

Maybe there's a more graceful way to handle the signal(SIGPIPE, SIG_IGN) response with systemd's default behavior.

MT8957s device via com port

Hello. I'm a little off topic.
In official programs under Windows OS for the MT8957s device, there is a setting "from where to read device data - from "usb" or from "com port"".
In this project, you will be able to read data only from USB.

Please help me find a way to read (and decrypt) data from the com port of this device.
I do not know the port settings, but it is there).

All this is necessary in order for the device to be located far from the computer and the data from the com port could be read by the esp module, for example, and sent to the smart home (home assistant)

How to kill process that was started from command make graph.rrd ?

Missing install target in Makefile

Are you plan add install target to make command? So it can be installed to system, avaivaible to all users and can be packaged for different distributives.

co2mond may get stuck and stop report values

Today I've noticed that co2mond failed to read data and got frozed. I had to restart it to get device readings again

As I can see in sources co2mond should try to reconnect to device in case of reading failure but somehow it have not happened.

I've noticed this issue just once during 2 months of using binary compiled from df58994, so it might occur really seldom.
