Model number 00439DIA1. Mounted on 3rd floor open deck as specified. Wind speed won't go above 14mph. Our normal is 15-25mph daily. Should I return it

Hello Sue, The National Weather Service recommends mounting the sensor 33 feet above ground with no obstructions within 100 feet for the most accurate wind speeds. You should receive an accurate reading for where it is mounted. We understand not all of our customers can mount this high. If you are comparing to a local news station, they typically follow the National Weather Service guidelines. If you have any other questions, or for further troubleshooting, please contact the AcuRite Support Team at 262-729-4852, we are happy to assist you. Thank you.
