This is fixed in Plasma 6.4.

Comment 3 Paolo Zamponi 2026-01-06 17:10:26 UTC

Unfortunately 6.4 didn't solve this issue for me. To be honest I run Plasma on more than a PC, and somewhere this is not an issue anymore.

But elsewhere if I follow the steps described in #1 message, then right click on the widget -> Configure sensors..., I can see my sensors in the Sensors details tabs, but not in the widget itself. This happens every times after the first reboot.
