The Unni UN0581 outdoor temperature display shows LL.L due to wireless interference between the weather station and the outdoor sensor. To fix this, restart both units and place them close together for about 20 minutes to re-establish a strong connection.

The UN0581 may display an incorrect temperature after changing the batteries because it takes 1–2 hours for the weather station and sensor to balance with the current ambient temperature after being sealed for a long time. Additionally, the sensor and station should be placed together within a couple of feet for about 20 minutes to ensure a strong connection. Incorrect placement, such as near heat sources or in direct sunlight, can also affect accuracy.

The outdoor temperature display shows "LL.L" on the Unni UN0581 likely because the temperature is below the device's measurable range or the sensor is not transmitting data correctly. Ensure the batteries are properly installed, placed within range, and paired correctly with the base unit.
