deCONZ logs

[neonal]

Hi,

I couldn't find where deCONZ writes log files. Can they only be seen from UI or are they written to the disk somwhere?

Thanks

deCONZ doesn't write log files to not pollute the sd-cards in long running setups.

But you can print and redirect logs to files via commandline.
For example a very noisy output can be generated as follows:

$ deCONZ --dbg-info=2 --dbg-zdp=1 --dbg-zcl=1 --db-aps=1 --dbg-http=1

Customize to your needs, for REST-API debugging the info and http options should be sufficient.

Oh great! That helped a lot, thanks :)

I have Deconz in Hassio running on ubuntu but I cannot seem to enter the logs using this command.

ubuntu_docker:~$ deCONZ --dbg-info=2 --dbg-zdp=1 --dbg-zcl=1 --db-aps=1 --dbg-http=1
deCONZ: command not found
ubuntu_docker:~$ 

Hope someone can tell me what to do!

If deCONZ is used with Ubuntu and as a service you can do the following:

$ sudo nano /lib/systemd/system/deconz.service

ExecStart=/usr/bin/deCONZ \
        #--dbg-info=2 --dbg-zdp=1 --dbg-zcl=1 --db-aps=1 --dbg-http=1 \
        -platform minimal \
        --http-port=80
#StandardOutput=file:/home/ubuntu/deCONZ-error.log
#StandardError=file:/home/ubuntu/deCONZ-error.log

If you delete the hashtag-comment, deconz is started with higher loglevel.

You can view the logifle during running the system with:

tail -f /home/ubuntu/deCONZ-error.log

@bramschats : As you see, decont is not usable everywhere and you neet the path: /usr/bin/deCONZ

Hello,
i tried to view log too but when i use the command above i got this error:

QCoreApplication::arguments: Please instantiate the QApplication object first
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.

what should i do to instantiate the QApplication?

You are using headless or desktop version ?
You need "-platform minimal" for headless

[clipse2004]

well, depending on whether I want the sensors to be displayed :)

[wkearney99]

if I'm running deconz on windows, where is the log?
