Alert Types
Every alert type available in LuxWX and what it monitors.
How Alert Types Work
Each alert type monitors a specific weather metric from your station. When the reading crosses your threshold, an alert is triggered. When conditions return to normal (with a safety margin to prevent on/off flickering), the alert resolves automatically.
Some alert types suppress less severe alerts in the same category. For example, if an Extreme Cold alert fires, the Frost Warning and Freeze Warning won't also fire — you'll only get the most severe notification.
Frost Warning
Triggers when air temperature drops below your threshold (default: 36°F / 2°C). An early warning before actual freezing.
Freeze Warning
Triggers at freezing (default: 32°F / 0°C). Suppresses Frost Warning — you won't get both.
Hard Freeze
Triggers at sustained sub-freezing temperatures (default: 28°F / -2°C). Suppresses Frost and Freeze warnings.
Extreme Cold
Triggers at dangerously low temperatures (default: 0°F / -18°C). Suppresses all lesser cold alerts.
Heat Advisory
Triggers when temperature exceeds your threshold (default: 100°F / 37.8°C).
High Wind
Triggers when sustained wind speed exceeds your threshold (default: 25 mph / 11 m/s). Useful for securing outdoor equipment.
Extreme Wind
Triggers at dangerously high winds (default: 58 mph / 26 m/s). Suppresses High Wind alerts.
Sustained Wind
Triggers when average wind speed stays above your threshold over a period, filtering out brief gusts.
Lightning Detected
Triggers when your station's lightning sensor detects any strike within range. A general heads-up that electrical activity is in the area.
Lightning Nearby
Triggers when lightning is detected within a closer range (default: 10 km / 6 miles). Suppresses the general detection alert.
Lightning Close
Triggers when lightning is dangerously close (default: 3 km / 2 miles). Suppresses both lesser lightning alerts. Seek shelter immediately.
Rain Started
Triggers when precipitation is first detected. Useful for knowing when to bring things inside or close windows.
Heavy Rain
Triggers when rain rate exceeds your threshold (default: 0.5 in/hr / 12.7 mm/hr).
Extreme Rain
Triggers at very high rain rates (default: 2 in/hr / 50.8 mm/hr). May indicate flash flood risk. Suppresses Heavy Rain.
Hail Detected
Triggers when your station detects hail impacts. Separate from rain — you'll get hail alerts even during rain.
Low Humidity (Fire Risk)
Triggers when relative humidity drops below your threshold (default: 15%). Low humidity combined with wind creates wildfire risk.
High Dew Point
Triggers when dew point rises above your threshold (default: 70°F / 21°C). High dew points feel oppressively muggy.
Tropical Humidity
Triggers at extreme dew points (default: 75°F / 24°C). Dangerous heat stress conditions. Suppresses High Dew Point.
Rapid Pressure Drop
Triggers when barometric pressure falls rapidly over 3 hours. Often precedes storms or severe weather.
Rapid Pressure Rise
Triggers when pressure rises rapidly over 3 hours. Can indicate strong wind shifts or clearing weather.
High UV Index
Triggers when UV index exceeds your threshold (default: 8). Apply sunscreen and limit sun exposure.
Extreme UV Index
Triggers at dangerous UV levels (default: 11). Avoid outdoor exposure. Suppresses High UV.
OSHA Heat Stress (WBGT)
Uses Wet Bulb Globe Temperature to assess heat stress risk for outdoor workers. Multiple severity levels from Caution through Extreme Danger, following OSHA guidelines.
Low Battery / Critical Battery
Monitors your weather station's battery voltage. Get notified before your station goes offline due to low power.
Station Offline
Triggers when your station stops sending data. Could indicate a power failure, network issue, or hardware problem.
Solar Production Anomaly
Compares your Tempest weather station's solar radiation reading against your SolarEdge inverter's actual production. When the sun is shining but your panels aren't producing as expected, this alert fires with an estimated daily dollar loss. Covers snow, dirt, shading, and equipment issues. Requires SolarEdge integration.
The alert only fires during daylight hours when solar radiation is above 200 W/m², and only when both your weather station and SolarEdge have sufficient data. Auto-resolves when production recovers.
Vineyard Alerts
LuxWX also offers specialized alerts for vineyards — frost risk forecasts, disease pressure, spray windows, and more. These use forecast models and accumulated data rather than simple thresholds.
