TempStick WiFi Temperature & Humidity Sensor
Gets an alert the moment your property hits a critical temperature — no subscription, no hub required. Perfect for vacation homes, greenhouses, and pipes. Made in the USA.
Surface temperature estimates use radiative cooling models adjusted for sky conditions, wind speed, humidity, and surface type. Dew point uses the Magnus formula. Frost point uses the Murray equation. Plant thresholds based on USDA horticultural guidelines. This tool provides estimates only — always verify with official NWS forecasts at weather.gov before taking protective action.
