The problem you are experiencing is that the Ecowitt Gateway driver
(formerly the GW1000 driver) emits the WS90 haptic rainfall data in fields
with a p_ prefix (eg p_rain instead of the default WeeWX field rain). The
reason for this is so as to not break support for existing tipping rain
gauges such as the WH40.
You have two courses of action. If you have no plans to add a tipping rain
gauge, such as the WH40, you can simply map the required internal Ecowitt
Gateway driver haptic rainfall fields to the traditional WeeWX rain fields.
Alternatively, if you may add a tipping rain gauge in the future you may
wish to modify the WeeWX database to store the haptic rainfall data. You
would then need to modify the Seasons skin to display the haptic rainfall
data.
Mapping the haptic rain fields to the traditional WeeWX rainfall fields can
be achieved with an alteration to the Ecowitt Gateway driver field map. To
do this:
1. edit weewx.conf and locate the [GW1000] stanza
2. at the end of the [GW1000] stanza contents (and before the next []
stanza starts) add the following:
[[field_map_extensions]]
rain = p_rain
rainRate = p_rainrate
3. save weewx.conf
Restart WeeWX and the WeeWX rain and rainRate fields should now be
populated with haptic rainfall data (when it rains of course). The Seasons
skin should now display rain data/plots without alteration.
If you wish to use the second approach you need to:
1. stop WeeWX if it is running
2. use the wee_database utility
<http://weewx.com/docs/utilities.htm#wee_database_utility> with the
--add-column action to add the columns (fields) p_rain and p_rainRate to
the database
3. edit the Seasons skin config file skin.conf (it should be located in
/home/weewx/skins/Seasons or /etc/weewx/skins/Seasons depending on your
WeeWX install type) and locate the [DisplayOptions] stanza
4. add p_rain and p_rainRate to the observations_current settings, it
should now look something like:
observations_current = outTemp, heatindex, windchill, dewpoint,
outHumidity, barometer, windSpeed, rain, rainRate, p_rain, p_rainRate, UV,
radiation, lightning_strike_count, inTemp, inHumidity, extraTemp1,
extraHumid1, extraTemp2, extraHumid2, pm1_0, pm2_5, pm10_0
note that obs will be displayed (if they exist) in the order they
appear in the list
5. repeat step 4 for the observations_stats, obs_type_sum and obs_type_max (
p_rainRate only) settings
6. locate the [ImageGenerator] [[dayimages]] [[[dayrain]]] stanza and
replace [[[[rain]]]] with [[[[p_rain]]]], eg:
[[[dayrain]]]
# Make sure the y-axis increment is at least 0.02 for the rain
plot
yscale = None, None, 0.02
plot_type = bar
[[[[p_rain]]]]
aggregate_type = sum
aggregate_interval = hour
label = Rain (hourly total)
7. repeat step 6 for [weekimages], [monthimages] and [yearimages]
8. save skin.conf
Restart WeeWX and you should find the p_rain and p_rainRate fields now
exist in the database and are populated (when it rains) and the Seasons
skin should display the haptic rain data. Note the Seasons skin will also
display the tradition rain data without modification if you ever add a
tipping rain gauge, but there will need to be some modification to the
image plot definitions to include both rain and p_rain data in order for
both rain and p_rain to be plotted.
