AcuRite Iris 5-in-1 Weather Station vs Ecowitt WS3900 Weather Station

The Ecowitt WS3900 is the better buy for most people. It adds UV and solar radiation sensors, a larger 7.5-inch screen, Wi-Fi with app and online uploads, and a 7-in-1 array, while the AcuRite Iris 5-in-1 is a simpler radio-only station with a color display and a self-calibrating forecast. Owners of the AcuRite praise the readable display and reliability but report rain gauge inaccuracy and units arriving defective; the Ecowitt kit is newer and less reviewed, so its long-term durability is less proven. Pick the AcuRite if you want a straightforward color station and don't need Wi-Fi or sun data.

• Choose the AcuRite Iris 5-in-1 if you want a simple color display station with a self-calibrating forecast and no need for Wi-Fi or app connectivity.
• Choose the Ecowitt WS3900 if you want UV and solar readings, a big 7.5-inch screen, and Wi-Fi uploads to apps and weather networks.
