hello,

to bounce back on this subject, I switched to V 4.2.0 too, I have this error message, can it come from my Wind sensor and vane which is not connected?

logs:

Nov 20 17:58:31 raspberrypi /weewxd: BYOWS RPi: Unknown Wind Vane value: 0.0

thanks

Patrick

    Gary,
    Sorry I slightly highjacked the topic, nothing to do with wind.
    Looking for a way to use a .tmpl to find the last record that is
    not null and the ignore caught my eye on the off chance. Will
    start a new thread if there is not a quick answer.
    Thanks
    Ian

        Ian,

        Short answer is no, ignore_zero_wind is the only
        StdWXCalculate option that affects wind direction. What do you
        want ignore_null (ignore_null_wind ?) to do? Pass through the
        wind vane direction if wind speed is None - if so
        ignore_zero_wind should do that.

            Whilst on the subject of ignore_zero, is there a similar
            expression for ignore_null?
            Thanks,

                There was a change to the StdWXCalculate service in
                4.2.0 that has inadvertently changed the operation of
                ignore_zero_wind. Normal (expected) operation should
                resume if you change the ignore_zero_wind setting to
                be the opposite of its current value (ie if under
                4.1.1 or earlier you had ignore_zero_wind = False
                change it to ignore_zero_wind = True or if you
                had ignore_zero_wind = True change it
                to ignore_zero_wind = False).

                If you don’t use ignore_zero_wind you are not affected
                by the change and need do nothing.

                    I have three pi's running weewx, two have been
                    moved up to 4.2.0, one is still on 4.1.1. All have
                    ignore_zero_wind set to False. The two that are on
                    4.2.0 no longer work as expected (zero wind shows
                    wind direction) but the 4.1.1 still works as expected.

                    Did something happen in 4.2.0 that changed the
                    behavior of ignore_zero_wind = False?
