The Raddy HW75 makes home climate monitoring simpler and easier to understand. Its large 7.5-inch display uses a modular color layout to separate temperature, humidity, barometric pressure, and forecast data into clear viewing zones for quick readability across the room. It also converts temperature and humidity data into 6 daily comfort indexes, including dampness risk and outdoor feeling, helping you better manage indoor comfort and changing weather conditions.

With support for up to 3 remote sensors, the HW75 lets you monitor multiple areas at once, including bedrooms, nurseries, greenhouses, garages, or wine cellars. The built-in RCC atomic clock keeps time automatically accurate, while USB-C power, adjustable brightness, and automatic night dimming make it a convenient fit for everyday living spaces.
　

Dual Power Options:

Use the USB-C power adapter for continuous, always-on backlight display as a vibrant desktop unit. Or switch to 2×AA batteries for a fully cordless setup with flexible placement anywhere in your home.

Feels-like & Heat Index:

Calculates the feels-like temperature based on real-time humidity and dew point, helping you understand whether conditions feel cold, comfortable, or hot for better outdoor planning and daily activities.
