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? On Thursday, August 20, 2020 at 2:41:03 PM UTC-6 gjr80 wrote: > Thanks, now I understand.
