I have a BIOS weather station. I cannot reset the daily rainfall back to zero on the monitor, and now it is not transmitting the daily amount to the weather analyzer software. It is recording the monthly and annual amounts, and everything else seems to be working. Any suggestions as to how I can get this to work? Thanks.

I have the same problem! I have only had the unit up and running for a few days. I'm using the updated software v2.214.
