Hi,
A few things. I sat down just now with to import your data from your first
post. I used the following field map:
[[FieldMap]]
dateTime = Time
usUnits =
interval = Interval(mi), minute
barometer = Relative Pressure(hPa), hPa
pressure = Absolute Pressure(hPa), hPa
altimeter =
inTemp = Indoor Temperature(°C), degree_C
outTemp = Outdoor Temperature(°C), degree_C
inHumidity = Indoor Humidity(%), percent
outHumidity = Outdoor Humidity(%), percent
windSpeed = Wind(km/h), km_per_hour
windDir =
windGust = Gust(km/h), km_per_hour
windGustDir =
rainRate =
rain = Total Rainfall(mm), mm
dewpoint = Dewpoint(°C), degree_C
windchill = Windchill(°C), degree_C
heatindex =
ET =
radiation =
UV = UV, uv_index
Points to note:
- If you wish to fill weeWX field interval from a field in you data then
in needs a mapping of the format interval = csv_field_name, weewx_units
(where csv_field_name is the field name in your csv data that holds the
interval value and weewx_units are one of minute or second). If you want
to set the interval field for all imported records to a fixed number,
say 10 minutes, then you should leave the interval field map blank and set
interval
= 10 in your import config file. Not particularly intuitive, but not too
many sources provide interval data and it is explained in the import config
file comments.
- Unfortunately wee_import does not handle ordinal/cardinal compass
directions for wind direction fields, only numerical degrees. One way
around this would be to change the cardinal/ordinal directions in your
import data to their degree equivalents then something like windDir =
Direction, degree_compass would work. Alternatively I could look into
modifying wee_import to handle cardinal/ordinal directions, at the
moment weeWX does not freely convert between degrees and cardinal/ordinal
compass points, something I would need to discuss with Tom. In any case at
least a week for me to make the changes
- I suspect your latest error is due to an incorrect csv field name. I
would suggest you are best deriving the weeWX rain field from the csv
field Total Rainfall(mm) - maybe that was your intent and you made a
typo? Refer to my field map above. One thing to watch is that when deriving
weeWX field rain from a cumulative rainfall field if the cumulative
field happens to rollover to 0 or otherwise overflow, you may end up with
incorrect data imported for that record. Usually you are best to use the
cumulative field that rolls over the least frequent.
- You can certainly import your lux field info into the weeWX field
radiation
but they are two different measurements - radiation is watts per square
meter (sic) and lux is in, well, lux (radiation will typically be in the
range 0 to 1600 odd - I think the theoretical limit is 1361 but for a
number of reasons some sensors can read higher than this). You may be able
to convert you lux data to watts per square meter and then import the data.
Alternatively, provided you have no radiation limits in you [StdQC] settings
in weewx.conf you could import you lux data and then manipulate the data
in the database to get data in watts per square meter. Of course you could
leave it as imported and accept that your radiation data is lux (expect
some units issues though if displaying using weeWX built in formatting)
- The UV field map should use units of uv_index.
