After upgrading Plasma 5 to 5.19.1, the “System Monitor Sensor” widget stopped working. There is no graph on it, and nothing is displayed on the “Sensor Information” tab. You can see it in the screenshots.
After the last update of kf5 to 5.70.1 and plasma5-plasma to 5.19.1, some widgets started working, but not all of them and very strange. Tab "Sensor Details" still does not work. Sometimes I cannot change "Display style". It either unavailable or does not work. Widget "Memory usage" does not work. But new widgets very cool!
This is mostly resolved by updating kf5-kitemmodels to 5.70.1_1, which installs the necessary QML parts for the configuration tabs.
The memory usage widget apparently uses sensors that have not been implemented in FreeBSD yet.

Well, after the update, I see this. It is a pity that the memory monitor stopped working, I hope this will be repaired soon. Thank.
It's being worked on (upstream, by me).
