[weewx-user] Re: Noob question... where to find the actual data (temp) within weewx?
I see that you mention "images" in your question, and it looks like you
have perhaps already got the answer you needed, but I wanted to reply to
this thread in case others are brought here later, with a response to the
question I *thought* you were asking (but I may have been wrong!).
I recently wrote a bash shell script (to be invoked by 'cron') that emails
me the previous day's rain total. To do so I invoke a SQL script to get the
data from the database, which is what I thought you were looking to do.
*#!/bin/bash*
*# email me summary of yesterday's local weather*
*# robcranf...@xxx.com*
*SQL_RESULT=`echo "SELECT DATETIME(MAX(dateTime), 'unixepoch', 'localtime')
\*
* AS Date, sum AS RainTotal FROM archive_day_rain WHERE dateTime < (SELECT
MAX(dateTime) \*
* FROM archive_day_rain);" | sqlite3 /var/lib/weewx/weewx.sdb`*
*SUBJECT=`echo $SQL_RESULT | awk 'BEGIN { FS="[| ]"} {print "Rain for",
$1}'`*
*MESSAGE=`echo $SQL_RESULT | awk 'BEGIN { FS="[| ]"} {print "The total rain
on", $1, "was", $3, "inches.\n"}'`*
*echo $MESSAGE |*
* mutt -s "$SUBJECT" -e 'my_hdr From:WeexReporter@x10pi' --
robcranf...@xxx.com*
HTH.

1) If you have another program wanting the temperature you can read it from the archive table in the database or 2) Create a template called temp.txt.tmpl containing $current.outTemp - and have cheetah create a file called temp.txt every archive interval which you can then read into your other program. or 3) Create a service, bound to loop records, to extract the outTemp from the loop record and create a text file every loop record On Sunday, 30 October 2016 23:29:29 UTC+2, Jim W. wrote: > Ok...

Ok... Maybe if I ask the question in a more clear form... Can someone explain how I can pass the current outdoor temp to a variable so I can us it in another program?
