AcuRite Iris 5-in-1 Weather Station vs Ambient Weather WS-2902

The Ambient Weather WS-2902 is the better pick for most people. It updates every 16 seconds, has built-in Wi-Fi for online weather networks and app alerts, and adds UV index. The AcuRite Iris 5-in-1 is simpler and cheaper-feeling, with a bright color display and a 12 to 24 hour self-calibrating forecast, but it has no Wi-Fi despite some listings suggesting otherwise. Owners of both rate them about the same, though the WS-2902 has far more ratings and fewer complaints about rain accuracy.

• Choose the AcuRite Iris 5-in-1 if you want a standalone color display on a table or wall and do not need Wi-Fi, app access or UV data.
• Choose the Ambient Weather WS-2902 if you want fast updates, Wi-Fi uploads to Weather Underground and phone alerts, and you plan to mount the sensor on a pole.
