Outdoor sensor temperature spikes in the morning

  • Problem
  • Updated 2 years ago
I recently received a 02027A1-RX AcuRite weather station as a gift. Having waited the prescribed period of time for the unit to "settle", I find I am still getting temperature spikes in the morning of anywheres upward of 20 degrees above the actual temperature. The unit does then settle down to the appropriate temperature for the rest of the day. I have placed the unit in several different areas on my boat (I'm a liveaboard) with the same results. Any ideas?

Good Afternoon Doug,

We recommend verifying the sensor is in a shaded area. Once you have verified the sensors placement and if you are still seeing a spike in temperatures we would recommend preforming a hard reset on both the sensor and the display. Please make sure you are using the recommended batteries; Rayovac, Duracell, or Energizer.

  1. Bring both the sensor and display unit indoors and position them side by side.
  2. Remove all batteries from the sensor.
  3. Remove all power from the display unit.
  4. Wait 1 minute to ensure that any remaining battery power has discharged from both units.
  5. Inside each battery compartment you'll find an A-B-C switch, be sure these match each other.  You may also want to try changing to a different setting.
  6. Reinstall batteries in outdoor sensor first.
  7. Reinstall batteries (and/or connect AC adapter) in display last.
  8. Let units sit within a couple feet of each other for 5 minutes to ensure a wireless signal is received.
    *The display should receive the signal within several minutes. 
  9. After a connection has been established you may place the sensor outdoors. 
    *If the signal connection fails after the units are separated try a new location for the display unit, the sensor or both.
