Great, Tom, thank you - the proposed (1st) solution looks quite smart
and is TESTED NOW - and works as expected.
Looks as if I have to enlarge my Python and Cheetah generator knowledge
significantly.
The 2nd will be helpful to implement that into my neowx-material skin
which was already parameterized before the Seasons skin was
"rejuvenated" into its new also parameterized coding.
When I have some more time, I'll also be looking into migrating my
Seasons skin ...
And I take it, that if I want to include more data-bindings, I just
enlarge the $archive_data array by more elements ... (1st solution)
thanks again
cheers

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>

After some more digging I have advanced:
my 2nd issue, that the monthly and weekly data is not shown seems
to be solved:
while in the imagegenerator the week/month means 7 days back and
30 days back from the current date,
$week and $month seem to mean the calender week and calender month
- a few tests with fake rain data in the database confirmed that
remains the issue how to show the values from the remote database
in the High/Low portion of the High/Low table
at http://www.weewx.com/docs/customizing.htm#Using_multiple_bindings
the example goes:
<table> <tr> <td class="stats_label">Inside Temperature,
Vantage</td> <td class="stats_data">$current.inTemp</td> </tr>
<tr> <td class="stats_label">Inside Temperature, WMR100</td> <td
class="stats_data">$latest/*($data_binding='wmr100_binding')*/.inTemp</td>
</tr> </table>
this translated into my hilo.inc code
<tr>
<td class="label">$obs.label.rain</td>
#for $archive in $archive_data
<td class="data new_row hilo_$archive[0]">
$archive[1].rain.sum.format(add_label=False)</td>
#end for
<td class="units">$unit.label.rain</td>
</tr>
<tr>
<td class="label">$obs.label.rainRate</td>
#for $archive in $archive_data
<td class="data new_row hilo_$archive[0]">
<span title="$archive[1].rainRate.maxtime">
$archive[1].rainRate.max.format(add_label=False)</span>
</td>
#end for
<td class="units">$unit.label.rainRate</td>
</tr>
should in my understanding then be:
<td class="data new_row hilo_$archive[0]">/*
*/$archive[1]/*($data_binding='rpi24-binding')*/.rain.sum.format(add_label=False)</td>
resp.
<td class="data new_row hilo_$archive[0]">
<span title="$archive[1].rainRate.maxtime">
$archive[1]/*($data_binding='rpi24-binding')*/.rainRate.max.format(add_label=False)</span>
</td>
where "rpi24-binding" is my database binding of the remote database
however, this produces a Cheetah Syntax error

what am I missing ?? - it's definitely the
/*($data_binding='rpi24-binding')*/ which causes the error - when
I remove it, no error is shown - but then I don't get my data from
the remote database ...

the background which made me run into the issue(s) which I
couldn't find a solution for yet -
nothing found in the WiKi either
2 Ecowitt stations - one has the WS90 and a WH40 rain gauge
connected, one the rain gauge from the WS69 array
2 weewx instances - one receiving the WS90/WH40 data, one
receiving the WS69 data
the instances run on different servers, but that was only an
additional challenge to figure out where to put the data_binding
information - maybe not yet completely solved - we'll see later
running weewx 4.8.0 - but with my old skin.conf - not (yet) with
the skin.conf which comes with the 4.8.0 install
I have added the following entries to my skin.conf - and the
plots of all three are properly shown - as desired
(for that I repurposed the wsview_extended database field "hail"
for the WS90 piezo rain)
####### excerpt skin.conf start ##########
[[[dayrain]]]
# Make sure the y-axis increment is at least 0.02 for
the rain plot
yscale = None, None, 0.02
plot_type = bar
[[[[rain]]]]
aggregate_type = sum
aggregate_interval = 3600
label = Rain (hourly total) (WH40)
[[[dayrain2]]]
# Make sure the y-axis increment is at least 0.02 for
the rain plot
yscale = None, None, 0.02
plot_type = bar
fill_color = "#ff4500"
[[[[hail]]]] #WS90 piezo rain
aggregate_type = sum
aggregate_interval = 3600
label = Rain (hourly total) (WS90)
[[[dayrain3]]]
# Make sure the y-axis increment is at least 0.02 for
the rain plot
data_binding = rpi24-binding
yscale = None, None, 0.02
plot_type = bar
fill_color = "#32cd32"
[[[[rain]]]] #WH65 rain
aggregate_type = sum
aggregate_interval = 3600
label = Rain (hourly total) (WS69)
############ excerpt skin.conf end ##############
HOWEVER, I couldn't manage to get the data from the external
database [[[dayrain3]] into the current data table - nor into the
High/Low table
_I couldn't figure out how to address the external database field
in current.inc and in hilo.inc to be shown in the table here._
Any advise how to manage that highly appreciated !
SECOND ISSUE: into which I ran while experimenting with the
hilo.inc file to get my values displayed
I found that even though the syntax seems to be correct, I only
get the current (that's current.inc) data displayed (for "rain"
and "hail")
but _I wouldn't get the weekly and monthly rain sums displayed -
only the yearly_.😮 - the others simply remain "0.0"
(it does the same in my other weewx installations too !)
excerpt below - what's wrong here and, also, referring back to
the first question, how would the code look like for the external
database field "rain" to be inserted to be displayed in that table ?
########### excerpt hilo.inc start ###########
#set $archive_data = [('day', $day), ('week', $week), ('month',
$month), ('year', $year), ('rainyear', $rainyear)]
