# Example for logging KS300 data into a DB.
|
|
#
|
|
# Prerequisites:
|
|
# - The DBI and the DBD::<dbtype> modules must be installed.
|
|
# - a Database is created/configured
|
|
# - a db table: create table FHZLOG (TIMESTAMP varchar(20), TEMP varchar(5),
|
|
# HUM varchar(3), WIND varchar(4), RAIN varchar(8));
|
|
# - Change the content of the dbconn variable below
|
|
# - extend your FHEM config file with
|
|
# notify .*H:.* {DbLog("@","%")}
|
|
# - copy this file into the <modpath>/FHEM and restart fhem.pl
|
|
#
|
|
# If you want to change this setup, your starting point is the DbLog function
