I'm working on a driver (based on Nev Davis's Raspberry Pi driver) and
skin.conf (Standard skin) for displaying measurements from four different
models of temperature and humidity sensors directly connected to a RPi. I
want to compare the readings from them side by side. The driver seems to be
working properly but in trying to make a custom skin.conf I get:
Feb 2 03:45:40 raspberrypi weewx[14174]: reportengine: Caught
unrecoverable exception in generator weewx.imagegenerator.ImageGenerator
...
Feb 2 03:45:40 raspberrypi weewx[14174]: **** File
"/usr/share/weewx/weedb/sqlite.py", line 41, in guarded_fn
Feb 2 03:45:40 raspberrypi weewx[14174]: **** raise
weedb.NoColumnError(e)
Feb 2 03:45:40 raspberrypi weewx[14174]: **** NoColumnError: no
such column: extraHumid3
So it's finding extraHumid1 and 2...
Here is the section from skin.conf (inHumidity is the average of the 4
values, computed in the driver):
[[[dayhumidity]]]
[[[[inHumidity]]]]
[[[[extraHumid1]]]]
[[[[extraHumid2]]]]
[[[[extraHumid3]]]]
[[[[extraHumid4]]]]
And here I am putting the values in the packet in the driver:
_packet = {'dateTime': int(time.mktime(raw_time)),
'usUnits' : weewx.METRIC,
'inTemp' : avgTemp,
'inHumidity' : avgHumid,
'pressure' : data[7],
'extraTemp1' : data[1],
'extraHumid1' : data[2],
'extraTemp2' : data[3],
'extraHumid2' : data[4],
'extraTemp3' : data[5],
'extraHumid3' : data[6],
'extraTemp4' : data[8],
'extraHumid4' : data[9]
}
At one point I remember seeing only up to extraHumid2 and extraTemp3
mentioned in the documentation (can't locate where that was) but elsewhere
I believe I have seen up to 7 of each.
Does the database code need to be modified for this to work? Thanks.
