Highlights

heat_index and wind_chill_temperature now show blank when conditions are not met. Trigger/condition menus no longer show hardcoded °C, mbar, m/s, or mm unit labels.

Changes

Heat Index and Wind Chill — blank (None) when conditions are not met

pyweatherflowudp returns None for these states when conditions are outside the calculation range:

State	Returns None when
heat_index	temperature < 80 °F or relative humidity < 40 %
wind_chill_temperature	temperature > 50 °F or wind speed < 3 mph

Previously, when the value was None the plugin skipped writing the state entirely — leaving whatever value was last recorded. This meant a stale reading persisted indefinitely, and a unit preference change (e.g. Celsius → Fahrenheit) would never be reflected until conditions happened to come back into range.

The plugin now always writes the state when None is received, storing None as the value with a blank display string:

Situation	value	Display
Conditions met — valid reading	95.3	95.3 °F
Conditions not met — None returned	None	(blank)

The None write is immediate — no stale value lingers after a weather change or unit preference update. Because these states are not typically used in numeric triggers, the None value is appropriate; the blank display clearly communicates "not applicable" rather than a misleading 0.

Trigger/condition menus — remove hardcoded unit annotations

The Indigo trigger and condition UI shows the state's TriggerLabel from Devices.xml in the state picker dropdown. These labels were annotated with hardcoded metric units — (°C), (mbar), (m/s), (mm) — regardless of the device's actual unit setting. A device set to Fahrenheit would show "Air Temperature (°C)" in the trigger dropdown, creating confusion about what unit to enter for the comparison threshold.

The unit suffix has been removed from all variable-unit TriggerLabel entries across the Tempest, Sky, Air, and Public Station device blocks. Fixed-unit labels (%, W/m², lx, UV, V, dBm, °) are unchanged.

Examples:

Before	After
Air Temperature (°C)	Air Temperature
Wind Speed (m/s)	Wind Speed
Station Pressure (mbar)	Station Pressure
Rain Rate (mm/h)	Rain Rate
Heat Index (°C)	Heat Index
Delta T (°C)	Delta T

The active unit is always visible in the state's current uiValue (e.g. 32.8 °F) and is also stored in the unit_temperature, unit_pressure, unit_wind, and unit_rain states.

Upgrade Notes

• No configuration changes required.
• TriggerLabel changes take effect after plugin reload — existing triggers continue to work unchanged.
• On the next observation after reload, heat_index and wind_chill_temperature will show blank if conditions are not currently met, clearing any stale reading.
