Ok that was very easy, good design. Thank you, I hope that sort of question is not too trivial for this group, perhaps it would be better asked on weewx-user? Wasn't sure since it seems like "development" to write a new driver, but in retrospect I could've found that in the documentation with just a little more searching.
One small change to the documentation I would make is to indicate that creating the _new database is not always necessary. Obvious perhaps, but deleting the old database had the same net effect as using wee_database weewx.conf --reconfigure and moving the new one over the old, unless I am missing something. I also deleted the existing reports if that matters. On Friday, February 2, 2018 at 4:34:27 AM UTC-8, Tom Keffer wrote: > > Yes.
