Ok, back again. Clean version of Ubuntu Server 20, with a new install of
weewx 4.1.1 installed via setup.py. Good so far.
Multiple instances configured, one using the FineOffSet driver (fousb), the
other using the Interceptor (WH2950) - both running and producing separate
reports with valid data that I can view via web browser.
I have then edited the wh2950.conf file to add a data binding to it from
the fousb:
[DataBindings]
[[wx_binding]]
# The database must match one of the sections in [Databases].
# This is likely to be the only option you would want to change.
database = archive_sqlite
# The name of the table within the database
table_name = archive
# The manager handles aggregation of data for historical summaries
manager = weewx.manager.DaySummaryManager
# The schema defines the structure of the database.
# It is *only* used when the database is created.
schema = schemas.wview_extended.schema
[[fousb_binding]]
# Binding for WH1080 on fousb
database = fousb_sqlite
# The name of the table within the database
table_name = archive
# The class to manage the database
manager = weewx.manager.DaySummaryManager
# The schema defines to structure of the database contents
schema = schemas.wview_extended.schema
##############################################################################
# This section defines various databases.
[Databases]
# A SQLite database is simply a single file
[[archive_sqlite]]
database_name = wh2950.sdb
database_type = SQLite
[[fousb_sqlite]]
database_name = fousb.sdb
database_type = SQlite
# MySQL
[[archive_mysql]]
database_name = wh2950
database_type = MySQL
When I restart the wh2950 instance, it starts without error - so far so
good.
I then edited the Seasons skin.conf file and added the "daycompare" section
as follows:
[[[dayuv]]]
# yscale = 0, 16, 1
[[[[UV]]]]
[[[daycompare]]]
[[[[inTemp]]]]
label = House inTemp
[[[[fousbTemp]]]]
data_type = inTemp
data_binding = fousb_binding
label = server inTemp
[[[dayrx]]]
yscale = 0.0, 100.0, 25.0
[[[[rxCheckPercent]]]]
I then get the following error saying that the 'fousb_binding' is unknown:

Hopefully there is a really obvious mistake that I can correct - i figure
if I can get the 'daycompare' to work, i will be able to extrapolate that
to the rest of the time intervals.
Thanks again, most appreciated.
