Oil level down at higher temp, to come up again

Hi guys, the oil sensor keep hazzle us, this was a new one to me after 7y ownership.

Car never drunk any oil between changes (5k). On a 500 miles weekend trip it suddenly went down one click from max and eventually another to mid bar. Decided to wait before topping up. After coming back home/cooling down, it was up at top again.
It was a fairly hot trip with a good 30C and I noticed the oil temp climbing from normal just under 100C to a needle above, maybe 105C.

The day after the meter comes to max (as Carly, 32.64). Puzzles me as never happened during 7y, anyone else experienced the sensor going crazy due to a few degress warmer oil (for hours)?

Cheers
