To restore the balance, I now exchanged the yellowed sensor from the sun-exposed south side balcony with the one from the shadowy north side garden.
Should keep it more even in the long run.

Could hit it with hydrogen peroxide and UV light.
I am more concerned about structural and functional degradation (e.g. one of the battery cells seems to have taken a hit during the >>40°C summer periods).
Hydrogen peroxide and more UV exposition unfortunately won’t help with that…
