In some cases I need to configure even 10 thresholds with description.

For example, in this case I have cut one thresholds in the widget and this is not good.

Temperature | Phytosanitary interpretation | Practical notes

< 5°C | Very low biological activity | Almost zero risk of infections, even if the leaves are wet

5—10°C | Low activity | Some fungi are activated, but very slowly

10—15°C | Moderate activity | Downy mildew can start to make a mess if it's wet

15—25°C | Optimal range for fungal growth | Maximum attention! Rapid infections with moisture

25—30°C | Still risky, but drier | Some mushrooms hold up, but evaporation increases

> 30°C | Fungal activity decreases, but beware of sunburn | Watch out for water stress or sunstroke
