It wouldn't
Try a reset of console and at same time go into diagnostic mode and check battery voltage. In my experience, low voltage is a major source of of erratic issues. Once I had a defective solar panel.
If all else fails, call Lonnie White at RainWise. He is a good man and helper. One of the company originals. I saw on Twitter feed he's in Vegas for trade show at present.
I'm thinking it's not the console because the IP-100 is reporting the same data. Don't they get their information independently from the sensor array? It's pretty consistent now. The wind direction on the Oracle keeps flip-flopping from S to NW and back again. I'm seeing the same thing on WU and rainwise.net.
Lonnie was a great help when I was purchasing my station. So far I'm not that impressed with Rainwise' support. Their phone support message says they'll try to get back to me in 24 hrs, and the email responder says 48 hrs.
EDIT: Are you saying that from diagnostic mode I can check the battery voltage from the sensor array? I'll try that.
The voltage varies between 6.39 and 6.42. Is that good? The data packets show many good packets but a few bad packets too. Software version is 18.60. I don't know what the byte count does.
