Comment 2 for bug 2002213

Version 0.5.0 was released 2 years ago, I would really suggest to get newer version.
However, I'm not sure how to get it in Raspberry PI OS, I never had one nor used one :(
I can try to gather info on how to install package manually, but that would be half the issue, I need to build one too on Raspberry OS.

Meanwhile, we need to figure out, why the notifications actually are not showing.
You see, log files do not contain much information, probably because logging level is low, please enable logging level to 2 and the send the log file.
Please send me the configuration files too, without them I can not determine, how much time you have assigned to user and whether notification should show up at all.

Do not forget to include client log and configuration files because they govern notification thresholds.

Maybe start with getting a little newer version from http://ftp.de.debian.org/debian/pool/main/t/timekpr-next/ , I think you need to choose armhf version, but I don't know which RPI you're using.
