dennis,
the drivers built-in to weewx are located in the weewx/drivers directory.
additional drivers are installed to the user directory.
has your 01035 ever worked properly with weewx? you might want to power
cycle the 01035 (remove batteries and disconnect usb), just in case the
firmware somehow got into a weird state.
there are two parameters that would affect you: use_constants and
ignore_bounds. these are specified in the [Acurite] section of your weewx
configuration file. the defaults should work with most stations.
if you have a 01035 or 01036 and you see 'unknown calibration constants',
then you should first try this configuration (you must restart weewx for
weewx.conf changes to take effect):
[Acurite]
...
use_constants = True
ignore_bounds = False
if you still see the 'unknown calibration constants' message, then try this:
[Acurite]
...
use_constants = True
ignore_bounds = True
if you still see 'unknown calibration constants', then try:
[Acurite]
...
use_constants = False
ignore_bounds = True
although if you get this far, your station is behaving in a way that no one
else has ever reported.
here are the comments about the parameters from the driver itself:
use_constants - Indicates whether to use calibration constants
when
decoding pressure and temperature. For consoles that use the HP03
sensor,
use the constants reported by the sensor. Otherwise, use a
linear
approximation to derive pressure and temperature values from the
sensor
readings.
[Optional. Default is
True]
ignore_bounds - Indicates how to treat calibration constants from
the
pressure/temperature sensor. Some consoles report constants that
are
outside the limits specified by the sensor manufacturer. Typically
this
would indicate bogus data - perhaps a bad transmission or noisy
USB.
But in some cases, the apparently bogus constants actually work,
and
no amount of power cycling or resetting of the console changes the
values
that the console emits. Use this flag to indicate that this is one
of
those quirky
consoles.
[Optional. Default is
False]
hope that helps,
