Acurite weather forcaster not showing outside temp

My National Geographic Weather Station is the opposite. The outside sensor only indicates the temperature, but the single CR2023 battery lasts a year. The inside unit on my desk lasts around 5 - 6 months and lets me know if needs a battery by showing the outside temperature as ' -- '

Although the manual says 'rechargeable batteries are not recommended', I would try 4 Sanyo Eneloop batteries. Or you could contact Acurite Support and ask them if your battery use is excessive?

The display has the internal sensor for temp and barometer, The 5 in one has the sensor for outdoors and shows temp, wind speed and direction, humidity and rain. With the added lightning detector having the additional temp sensor in it, the system is redundant. It is recommended to put the sensor outside for best results that t have the least interference and maximum range..

take it back as it is not fit for the purpose
have it checked under warranty

We would recommend a reset of your unit. Please verify that you are using good-quality, standard alkaline batteries such as Energizer or Rayovac, then follow the steps below.
1. Bring both the sensor and display unit indoors and remove at least one battery from each.
2. Make sure the A-B-C switch on both units match. Sometimes changing to a different channel can help.
3. Reinstall the battery in the outdoor sensor.
4. Reinstall the battery in the display unit.
5. Let the units sit within a couple feet of each other for about 20 minutes to gain a strong connection.
If you need any further assistance, please contact AcuRite Customer Support at 1-877-221-1252 or [email protected].

Try taking the inside unit outside as close to the transmitting unit as possible for three minutes. The signal might lock on to the setting you want to receive.

outside temp

HH means it is showing the high temperature you (most likely accidentally) set with the MAX MIN / + button, which is easy to do when setting the clock. Just press that button again until the reading appears.

Sometimes the RF frequency from the outside transmitter loses contact with the clock's frequency ( it has happened to me only twice in 6 years ), and then the outside temp will not show. Simple solution to fix this is: Take down the outside transmitter and the internally mounted clock. Remove batteries from both. Wait about 10 mts. First install batteries in the transmitter, then after about 30 seconds, install batteries in the clock. In about 5 mts, you will find the clock showing the external temp like before.
