Hello,
I have had this problem and solved it for my VPro2 by modifying the
vantage.py driver. It was suggested to me several years ago because I'm
using the RS232 interface which is designed for APRS (ham radio) reporting.
Not sure I understand why it works but it does for me and I need to modify
each new driver file (vantage.py) when I update weewx.
I made the following modification:
In vantage.py:
def genLoopPackets(self):
"""Generator function that returns loop packets"""
while True:
# Get LOOP packets in big batches This is necessary because
there is
# an undocumented limit to how many LOOP records you can request
# on the VP (somewhere around 220).
for _loop_packet in self.genDavisLoopPackets(2): #[this is set
to 200 in vantage.py original]
yield _loop_packet
My archive time is set to 15 minutes, if this is important.
Good luck.
Bob
