Is there censor available for a 308-2316 weather station that will make the outdoor temp more accurate?

If it is like mine, the CR2032 battery in the base station only lasts about 6 months, whereas the one in the outdoor unit lasts over a year. Try this though. Remove the batteries from both units. Replace the battery in the indoor unit and then in the outdoor unit. It should re-register it.

Remove all batteries from outdoor sensor and weather station.

Press one of the buttons on the weather station at least 20 times to clear all memory.

Verify that the weather station is blank before proceeding (there may be lines painted on
the screen that will show when power is removed).

Leave both units without power for 15 minutes (very important).

Insert fresh batteries into the clock.

Insert fresh batteries into the outdoor sensor.

Press the TX button on the outdoor sensor to transmit RF signal.

Keep the outdoor sensor 5-10 feet from the forecast station.

When RF connection is established, the temperature will appear on the station. Allow the
outdoor sensor and weather station to sit together for 15 minutes to establish a strong
connection.

Here's the manual for the AcuRite Weather Forecaster. If it's not showing the outside temperature, make sure the A-B-C switch is set to match the display unit. Not doing so might be the reason it's not synchronizing and displaying the outdoor temperature. https://www.acurite.com/media/manuals/75077-75107-instructions.pdf

There are a couple of possibilities for the failure to transmit/receive outdoor data. First, resynch the two units. This will depend on the manufacturer. For some brands, you need to take the batteries out of both the indoor and outdoor units for 10 minutes. Then put the batteries into the devices with both side by side (working inside is easier). Wait until the outdoor data is displayed. There are some weather station systems where the outdoor unit isn't weather-proof. You may need to dry the outdoor unit for several days after removing the batteries before resynching it to indoor sensor.

If the data displays properly when the outdoor unit is inside, you may have the outdoor sensor too far away from the indoor unit. (The distance will depend on the number of walls and the composition of the wall studs/siding.) Try keeping the two units closer together.

If the outdoor data isn't displayed when the two units are side by side and the reset procedure doesn't work. One device has an internal malfunction (transmitter or receiver failed). It's probably best to replace the unit. If it is under warranty, contact the manufacturer.

I hope this helps. For specific details on resetting the indoor and outdoor units to synch them, please add a comment with the make/model of your weather station.

(I've seen Davis Weather stations damaged by a close lightning strike. The outdoor unit had to be replaced.)

Try replacing the battery in the outside temp transmitter.

I have experienced the same with numerous different, "quote un quote" atomic clocks! Please don't forget that this sender unit, that goes outside, generates a RF Singal to be received by the clock inside. This unit transmits a signal 433 MHz signal approximately every. 3 minutes, and after so many years the sender unit's RF section(electronics) just goes out or no longer function properly or not at all! The transmitter/sender for this model number, according to "3M" is obsolete and can no longer be furnished, DRATTS !!!!!

I have the same problem. Any ideas? My guess is that the outside temp sensor is defective.

I had the same problem, Since the outside temp wouldn't read, I figured it was the outside unit batteries. Went through half a dozen AAA batteries and wouldn't read. It was the indoor unit. Had the same bats I installed 3 years ago. DUH! Replaced the AAA, and all was well. When the inside batteries die out, it has just enough juice to read indoor temp, but not enought to sense exterior signal.

The signals are not being received by the main unit. Try to reposition the unit or move it to a different location. Also make sure the antenna is in the clear and not next to any thing like a cordess phone or charger as these can make RF noise that can block or cover the needed signals.
