Hello,
I tried to implement a driver providing the rainfall in intervall but until
now it does not work as expected.
I'am able to handle the correct data to WeeWx with this command:
syslog.syslog(syslog.LOG_DEBUG, "WeatherDuino: " +
str(names[n+1]) + ": " + str(deltarain))
event.record[str(names[n+1])] = float(deltarain)
The debug log output says:
> Mar 3 11:56:16 WeatherDuinoPi weewx[1366]: WeatherDuino: Rain_RG11:
> 0.17716535433
>
But in the database there is a "0" logged.
If i change the code hardcoding the rain intervall to 10 it works fine.
syslog.syslog(syslog.LOG_DEBUG, "WeatherDuino: " +
str(names[n+1]) + ": " + str(10))
event.record[str(names[n+1])] = 10
So I think my driver is executed more often then my one minute logging
intervall and so the value of the event.record is overwritten with a zero
again - because the driver thinks the value is already in the WeeWx
database.
You can find my code here:
https://github.com/menachers/WeatherDuino/tree/master/WeeWx_Plugin
It is embedded in the weewx.conf:
# This section configures the internal weewx engine.
[Engine]
[[Services]]
# This section specifies the services that should be run. They are
# grouped by type, and the order of services within each group
# determines the order in which the services will be run.
prep_services = weewx.engine.StdTimeSynch
data_services = user.WeeWx_WeatherDuino_Logger_plugin.WeeWxService,
process_services = weewx.engine.StdConvert, weewx.engine.
StdCalibrate, weewx.engine.StdQC, weewx.wxservices.StdWXCalculate
archive_services = weewx.engine.StdArchive
restful_services = weewx.restx.StdStationRegistry, weewx.restx.
StdWunderground, weewx.restx.StdPWSweather, weewx.restx.StdCWOP, weewx.restx
.StdWOW, weewx.restx.StdAWEKAS
report_services = weewx.engine.StdPrint, weewx.engine.StdReport
