No bluetooth or wifi pairing. No app. Well made with both magnets and a kickstand. Easily read especially with USB connection. Accurate. A fairly loud alarm that can be heard through a few finished basement rooms. Used with two Peltier coolers. Important to know if the fan malfunctions or the power is off beyond the power supply battery backup they are attached to since one of the two will not start up automatically when the power is restored. A really good value since one works for two coolers. ## Frequently Bought Together - Indoor Outdoor Thermometer Hygrometer Wireless Weather Station, Temperature Humidity Monitor Battery Powered Inside Outside Thermometers with 330ft Range Remote Sensor and Backlight Display - Duracell Coppertop AAA Batteries with Power Boost Ingredients, 24 Count Pack Triple A Battery with Long-Lasting Power, Alkaline AAA Battery for Household and Office Devices --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/635198865-u-unni-indoor-outdoor-thermometer-hygrometer-wireless-weather-station-temperature](https://www.desertcart.vu/products/635198865-u-unni-indoor-outdoor-thermometer-hygrometer-wireless-weather-station-temperature) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
