I have this model and the outdoor temp sensor isnt working, and yes both modules have brand new batteries in them. what should i do to get the outdoor temp sensor to work.

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..

I'm not finding that model but yes, unlikely, if two separate outdoor units that both are damaged. Either there simply isn't one and the configuration is not right or the connection is loose or sensor is not secure.

since this question is very non specific i.e., no brand name, model or serial numbers, I can only assume that this is the type of unit that monitor the outdoor temp and does not require any settings. If you need more info, please include more details. Thanks.

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.)

Hi Jim, what make/model station do you have? Normally there is a search function on the main unit to find the outdoor unit. After that they should sync and the outdoor temperature will reflect the temperature of where the outdoor sensor is located.

Hope this helps.

Did you reset the sensors after replacing the batteries? Bring the sensor inside and close to the main unit. Replace batteries on both units. Use a thumb tack and stick it into small reset hole near battery compartment to reset both units. If that doesn't work, your sensor needs more troubleshooting or needs to be replaced.

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

To get the outside temperature working again, open the outdoor sensor box carefully loosening the one screw with a screwdriver, insert 3 brand new AA batteries, check phone for outside temperature. If not showing on the phone display, try changing the 'channel' setting, just above the batteries. Be careful not to break the tiny switch. Gently use a smaller flathead screwdriver, if needed. There are 3 settings. Mine worked fine on the first setting. If it is showing on the phone set screens, then, carefully screw the lid back on to the sensor box, and re-insert into the sensor wall holder. I keep mine in a plastic bag on a shelf outside, away from sun, so I can get a true reading day or night. It is always a bit warmer in the sunlight than the true outdoor air temperature. Enjoy

After replacing the transmitter batteries several times, I tried replacing the clock batteries. They must have been getting low. Once I put in new batteries in the clock it worked fine. Good Luck.
