SUMMARY Between boots, sensors randomly swap with each other. As in you add and name `/dev/sda` and `/dev/sdb`, reboot, sometimes the name you gave to `/dev/sda` is swapped with `/dev/sdb`. This leads to the system monitor widgets misleading you about which drive is being used. I know this is because Linux doesn't guarantee the `sd*` names are consistent between boots, but the widgets should probably be using UUIDs which *are* guaranteed to be consistent between boots. STEPS TO REPRODUCE 1. Have a PC with more than 1 SSD/HDD (not NVMe) 2. Open System Monitor 3. Add a new page 4. Edit the page 5. Click on the widget 6. Set Display Style to Line Chart 7. Add a sensor for SSD/HDD and a sensor for a different SSD/HDD 8. Reboot and check if they've swapped OBSERVED RESULT Sometimes they swap. EXPECTED RESULT They don't.

Thank you for the bug report! However Plasma 6.3.6 no longer receives updates or maintenance from KDE; active versions are 6.4 or newer. Please upgrade to an active version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need help with Plasma 6.3.6, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE. If you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
