Current Conditions are all N/A - stale data, WUnderground working though? (maybe)

[Jacob Mann]

A short while back, my Acurite 01035 hooked up via Raspberry Pi stopped showing "current conditions"

The Wunderground page also showed 0degrees when you logged into it... but both Wunderground and the local webpage maintained highs/lows.
My receiver itself seems to be working fine.

When I run sudo tail -f /var/log/syslog --- I get the following -- seeing a lot of "stale data"

The sensor status says signal quality is 0%, and the battery is low. But the inside display where the USB is plugged into is displaying all data as expected. Updates and everything else.

It's also pulling inside temp and outside wind just fine. So where's the other data??
