OK, I placed this at the end of weewx.conf:
# Options for extension 'GW1000'
[GW1000]
driver = user.gw1000
[[field map]]
extraTemp2 = intemp
extraHumid2 = inhumid
extraTemp1 = temp1
extraHumid1 = humid1
soilMoist1 = soilmoist1
Result is the same as before; the first two lines produce null values in
the database, and the latter three appear in the correct fields. In fact,
it doesn't seem to matter what I put in this file. For example:
# Options for extension 'GW1000'
[GW1000]
driver = user.gw1000
[[field map]]
extraTemp2 = intemp
extraHumid2 = inhumid
extraTemp1 = foobar1
extraHumid1 = foobar2
soilMoist1 = foobar3
produces the same results! The first two lines give nulls; foobar lines
work. Is this the correct format and location for a field map?
