No valid humidity data from rtl_davis. Normal vantage console shows good
data, as well as Weewx directly connected to it. It is a pretty old VP2
from April of 2006.
Had run this at one point:
Davis Vantage EEPROM settings:
CONSOLE TYPE: VantagePro2
CONSOLE FIRMWARE:
Date: Sep 29 2009
Version: 1.90
CONSOLE SETTINGS:
Archive interval: 300 (seconds)
Altitude: 161 (foot)
Wind cup type: large
Rain bucket type: 0.01 inches
Rain year start: 1
Onboard time: 2017-09-06 16:41:30
CONSOLE DISPLAY UNITS:
Barometer: mbar
Temperature: degree_F
Rain: inch
Wind: mile_per_hour
CONSOLE STATION INFO:
Latitude (onboard): +42.5
Longitude (onboard): -71.2
Use manual or auto DST? AUTO
DST setting: N/A
Use GMT offset or zone code? GMT_OFFSET
Time zone code: N/A
GMT offset: -4.0 hours
TRANSMITTERS:
Channel 1: iss
Channel 2: wind
Channel 3: (N/A)
Channel 4: (N/A)
Channel 5: (N/A)
Channel 6: (N/A)
Channel 7: (N/A)
Channel 8: (N/A)
RECEPTION STATS:
Total packets received: 24
Total packets missed: 0
Number of resynchronizations: 0
Longest good stretch: 24
Number of CRC errors: 0
Thanks
