Hello,
I use a RPI using a USB-RS232 converter with a Lacross WS2350 since 
December 2014 with Weewx 2.7. This last July, I upgraded the Weewx to 3.5 
and since a week ago the 3.6.0 or above version.
I notice with these last versions the rain values include in the NOAA 
reports are wrong. I checked the data and I noticed these 2 points :
* The values in the NOAA report are x10 higher than in the SQL database in 
the archive_day_rain table
* The values of the NOAA report compared with other local station are very 
different. The ratio seem to be around of 0.66 from the measurement I get.

The reference site :

Is some one have any idea to solve this issue ?

PS: In the WS23xx.py driver it's necessary to have a delay in the delay 
read definition :
This sleep time allows to solve the hazardous or wrong reading data from 
the station. It's due to communication between the station and the outside 
sensors in the same time.

    def read_byte(self, timeout=1.0):
        if self.log_mode != 'r':
            self.log_mode = 'r'
            self.log(':')
        result = self.serial_port.read_byte(timeout)
        if not result:
            self.log("--")
        else:
            self.log("%02x" % ord(result))
        time.sleep(0.01) # LSA use to slove synchro rs232 data in
        return result
