  If your AcuRite Weather Station's wireless signal indicator shows no bars, here are some things to try: * Relocate the display and/or the outdoor sensor, ensuring they are within 330 ft (100 m) of each other. * Position both units at least 3 feet (.9 m) away from electronics that could cause interference, such as TVs, microwaves, or computers. * Use standard alkaline batteries (or lithium batteries in the sensor when the temperature is below -4ºF/-20ºC). Avoid using heavy-duty or rechargeable batteries. Keep in mind that it may take a few minutes for the display and sensor to synchronize after replacing the batteries.

Why is my AcuRite Weather Station forecast inaccurate?
- R
  Richard GuzmanAug 10, 2025
  There are a few reasons why the forecast on your AcuRite Weather Station might be inaccurate: * The Weather Forecast icon predicts conditions for the next 12 to 24 hours, not the current conditions. * Check if the learning mode icon has disappeared from the display. Learning Mode must complete before the forecast and pressure will be accurate. * Allow the unit to run continuously for 33 days. Removing the battery or resetting the display will restart Learning Mode. The forecast should become fairly accurate after 14 days; however, Learning Mode calibrates for a total of 33 days.
