Hello,
Up to the 22. March i used WU as provider for forecast with the setting
num_periods = 72 in skin.conf This setting works for forecast_table.inc
from version 3.2.0 included in index.html.tmpl from weewx version 3.8.2.
Since WU shut down the old Api i try to use Open Weather Map an Dark Sky
cause NWS has no data für Germany.
first i set in weewx conf only the API keas for OWM an DS
In version 3.2.0 OWM raises an error in /log/message.

So i do an update to weewx 3.9.1 and forecast 3.3.2. Now i see in message
for the OWM Thread

Apr 4 18:21:01 unimatrix-rasp weewx[18529]: forecast: OWMThread: OWM: got
40 forecast records
and nothing else, also no errors,
i set in skin.conf
[[forecast_table_settings]]
source = OWM
num_periods = 72
but the table on the website shows "No Data for OWM forecast"
then i try the API from Dark Sky
in weewx.conf i set also
[[DS]]
api_key = 162f
interval = 3600
max_age = 604800
now i see in messages for example:

deleted forecasts prior to 1553857252
i set in skin.conf
[[forecast_table_settings]]
source = DS
num_periods = 72
the table shows now 7 days forecast in the table, num_periods seems not
working
i can reduce this to 4 or 3 days by using
num_days = 4 (or 3)
But, the forecast starts everytimes from tomorrow. With data from WU and
num_periods = 72 in the first row it shows the forecast from today in row 1
+ 2 Days in rows 2 and 3. From 8pm to 12pm it shows today in row 1 + 3 days
in rows 2 to 4.
With data from DS it shows i row 1 forecast for tomorrow.
you can see this on my webpage (www.balkonwetter-dachau.de)
2 Questions:
How can i configure that DS shows the forecast starting from today and not
from tommorow
What's wrong that OWM dont work? It seems from OWM weewx gets data but dont
store them.
My setup:
weewx 3.9.1 with forecast 3.3.2 runs on a Raspberry Pi. The data storage is
a mySQL Database that runs on my Webserver (a VPS from contabo.de).
