It looks like you are using an older version of Seasons (before it was
parameterized). The variable $archive[1] is the result of evaluating $day,
which makes it an instance of weewx.tags.TimespanBinder, built using
default values in the initializer. At this point, it's too late to ask it
to be built using a custom value for data_binding.
What to do? You could introduce a new set of timespans, this time including
your custom binding. It would look like (NOT TESTED):
#set $archive_data = [('day', $day, $day(data_binding='rpi24-binding')),
('week', $week, $week(data_binding='rpi24-binding')), ('month', $month,
$month(data_binding='rpi24-binding')), ('year', $year,
$year(data_binding='rpi24-binding')), ('rainyear', $rainyear,
$rainyear(data_binding='rpi24-binding'))]
then use that when necessary:
<td class="data new_row hilo_$archive[0]">
<span title="$archive[1].rainRate.maxtime">
$archive[2].rainRate.max.format(add_label=False)</span>
</td>
Another approach would be to update to the parameterized version of
Seasons, which does its evaluation of TimespanBinder later, allowing it to
be modified in a more straightforward way:
<td class="data new_row hilo_$timespan">
<span title="$getVar('%s.%s' % ($timespan, $x)).maxtime">
$getVar('%s.%s(data_binding='rpi24-binding')' % ($timespan,
$x)).max.format(add_label=False)</span>
</td>
