      Renee SullivanAug 22, 2025
      If the live data on your Oregon Scientific Accessories Weather+ app isn't refreshing when you press the refresh button, please note that it may take a few seconds for the data to update. If you've already pressed the button once, wait 15 seconds before pressing it again. Also, ensure that the Weather+ and your smart device are within the 30 m (98 ft) Bluetooth range.
