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.


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.
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.
Tracks indoor comfort and dampness levels with clear High, Medium, and Low indicators, helping you know when to adjust your AC or dehumidifier for a healthier and more comfortable living space.

Radioddity fulfills orders from warehouses in the United States, Canada, the European Union, the United Kingdom, and international locations. The fulfillment location for each item depends on its delivery destination and current inventory availability. If regional inventory is unavailable, an eligible item may still ship internationally.
Where a delivery-country selector is available on a product page, use it to check that item's current availability and estimated transit time. Your available shipping methods and final charges are confirmed at checkout.
Most orders are processed within 1–2 business days after payment is confirmed, excluding weekends and public holidays. Processing is the time needed to prepare an order before it is handed to the carrier; it is separate from transit time.
Processing may take longer during major sales, new product launches, holidays, or other high-volume periods. If an ordered item is temporarily out of stock, our customer service team will contact you so you can choose to wait or cancel the order.
The route depends on the item, delivery destination, and available inventory. Shipping method names do not indicate a fixed dispatch warehouse.
| Fulfillment route | Delivery destination | Estimated transit time |
|---|---|---|
| US warehouse | United States, when US inventory is available | 3–5 business days after dispatch |
| Canadian warehouse | Canada, when Canadian inventory is available | 3–7 business days after dispatch |
| EU warehouse | European Union, when EU inventory is available | 3–6 business days after dispatch |
| UK warehouse | United Kingdom, when UK inventory is available | 1–3 business days after dispatch |
| International fulfillment | Eligible destinations, including Brazil, Chile, Colombia, and orders fulfilled internationally when regional inventory is unavailable | 7–15 business days after dispatch |
Processing time is not included in these estimates. Business days exclude weekends and public holidays. Transit times are estimates, not guaranteed delivery dates; carrier delays, customs clearance, weather, and remote-area delivery may affect arrival.

Orders with multiple items, including bundles, may be fulfilled from different warehouses and arrive in separate packages or on different dates. Tracking information is provided for each shipment when available. Please check all tracking numbers if only part of your order has arrived.
For orders delivered to the United States or European Union, import duties and customs charges are covered in the price paid to Radioddity. You will not be charged those fees a second time when your parcel is delivered.
For European Union orders, displayed product prices include VAT. Any applicable taxes calculated at checkout, including taxes on shipping where required, are shown before payment. For customs questions about other destinations, please contact us before ordering.
Pre-orders, outlet items, open-box items, and other specially marked products may have different processing times, delivery options, or shipping charges. Product-specific information and the checkout options take priority over the general estimates in this policy. Remote destinations may take longer to reach.
If you need to change a shipping address or cancel an order, email support@radioddity.com or send us a message as soon as possible. Some orders ship soon after placement, so a change or cancellation cannot always be made.
