I think they have a bunch of bad sensors, lot's of post about same thing, reading -40.  Probably will need a new sensor.

Hello Brad,

What is the model number of your weather station? What is the name brand of the batteries you are using? Are you able to test the batteries with a  voltage meter. The -40 doesn't have to do with the batteries. It is an error message the sensor gives.   

You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios. Follow the battery guidelines below:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.

•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.

•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.

•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.

•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.

•Mixing different battery types (brands, old/new, etc.) is not recommended.

Perform a hard reset:

1.Bring both the sensor and display unit indoors side by side.

2.Remove batteries from the sensor.

3.Remove batteries from the display unit and unplug the AC adapter (if applicable).

4.Wait 2 minutes to ensure any remaining battery power is discharged from both units.

5.Change the A-B-C Channel on both the display and sensor making sure they both match.

6.Reinstall batteries in outdoor sensor first.

7.Reinstall batteries in display unit second.

8.Let the units sit within a couple feet of each other for 30 minutes when comparing for accuracy
* 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 or different location for the display unit, the sensor or both.

After removing sensor from outside and replacing the batteries, they don't communicate with each other

I have tried new duracel coppertop batteries fresh from the store, tested on a meter reading 1.60-1.61v.

I have changed channels from c,b&a. No response from reach other.

Not communicating with reach other inside house

Hello Brad,

If your sensor is not connecting to the display at this time, we would recommend replacing the sensor. When was this purchased?  Thank you.
