I have a 01025 5 in 1 sensor, and display; this setup has been working fine for years.

Today, I noticed no Low Battery Indicator and just a flashing icon for the signal strength.  I unhooked power to reset and just getting in ticker, looking for 5 in 1 sensor.  Batteries have been changed before, but not sure on last time now.

Also I notice today loud noise from 5 in 1 sensor, not sure if it is the anemometer or wind vane.  (am thinking the anemometer.)   Wonder is I should just replace the 5 in 1 or new batteries?

No fun in this weather getting up on garage roof!  Thanks

The noise is probably the aspiration fan going bad or has debris in it. Remove the perimeter screws (not the tip bucket ones) and split the case. the fan should move freely, and spin on its own in sunlight.

Low Batteries, only applies to the unit that contains them. If you have a Smarthub or Access, log into that. It shows sensor battery status.

Thank you, I do have the Acu-Line Internet Bridge, I think this is what you mean for Smarthub/Access, when I log in I don't see anything on batteries in the 5 in 1 Sensor.  I guess tomorrow I will get sensor down and into house to replace batteries and clean inside of sensor and go from there.  Again, thank you.  AJ

The 'bridge' may be too old
Here is what my smarthub shows

Hello AJ,

You should hear a slight hum coming from the sensor when the fan is running. If it is louder than that it could be the bearings in the wind cups. They may need some lubricant on them.  You also want to check the fan for debris. While you have your sensor down we would also recommend lubricating the bearings.

Step 1.
Remove the four outer screws on the bottom of the sensor. Keep the screws for re-assembly.

  • Note: Be careful not to remove or adjust the rain calibration screws located beneath the rain gauge.

Step 2. 
Separate the upper and lower halves of the sensor.

Step 3.
Check the fan for debris, such as insects or spider webs. A gentle puff of air can clear most obstructions safely

If no debris appears to be blocking the fan, position the top white portion of the sensor (that has the solar panel) in direct, bright sunlight. The fan should power on immediately without any assistance (such as a nudge). Note: Artificial light, such as flashlights, cannot be used as a substitute for actual sunlight. Also, overcast days may not be sunny enough to power on the fan.

Step 4.
To reassemble the sensor, bring the two halves of the sensor back together

Step 5.
Reinstall the four outer screws to join the upper and lower portions of the sensor together.
