Thresholds
Customize the temperature gauge thresholds.
Temperature thresholds define the four transition values that create the five gauge zones: red-low, yellow-low, green, yellow-high, and red-high.
temperature_thresholds: [15, 20, 29, 32]
The default pool preset is [15, 20.5, 29, 32]. A spa-friendly preset commonly uses [35, 37, 39, 40].
Only temperature thresholds can be customized.
Keep the values strictly increasing. If two adjacent values are equal or out of order, the editor rejects the change.
