I’m almost done with a very stable version of the Python code running the PiPlanter. There are many specific differences between this version of the python code and the version I wrote and implemented last summer, but the main one is that I tried to write functions for pretty much every task I wanted to do, and made each routine much more modular instead of one long line after line block to do each day. This took significantly longer to do (thus the lack of updates, sorry) but is much more expandable going forward. Below is the new version of the code, but by no means am I an expert programmer. The following code seems to work very well for what I want it to do.

Note the distinct lack of comments. I will put out a much more polished version of the code when it’s done. Before I move onto things like a web UI etc, I would like to do a few more things with this standalone version. The above version renders videos into time lapses, I would like to be able to upload those videos somewhere, hopefully youtube. I would also like to be able to email the log file to the user daily, which should be easier than uploading videos to youtube.
The script that renders the MySQL data into a graph is the following, it on the other hand has not changed much at all since last year and is still the best method to render graphs like I want to:
<?php
/* Include all the classes */
include("/srv/www/lib/pChart/class/pData.class.php");
include("/srv/www/lib/pChart/class/pDraw.class.php");

mysql_select_db("PiPlanter_Database", $db);
$Requete = "SELECT * FROM DailyTable07_11_2014__04_05_09PM";
$Result = mysql_query($Requete, $db);
/*This fetches the data from the mysql database, and adds it to pchart as points*/
while($row = mysql_fetch_array($Result))
{
$Time = $row["Time"];
$myData->addPoints($Time,"Time");
$P_MST0 = $row["P_MST0"];
$myData->addPoints($P_MST0,"P_MST0");
$P_MST1 = $row["P_MST1"];

$myData->addPoints($A_TMP0,"A_TMP0");
$A_LDR0 = $row["A_LDR0"];
$myData->addPoints($A_LDR0,"A_LDR0");
}
$myData-> setSerieOnAxis("P_MST0", 2);
$myData-> setSerieOnAxis("P_MST1", 2);
$myData-> setAxisName(2, "Relative Moisture [%]");
$myData-> setSerieOnAxis("A_TMP0", 0); //assigns the data to the first axis

$myData-> setAxisName(1, "Ambient Light Level [%]");
$myData->setAbscissa("Time"); //sets the time data set as the x axis label

Here are some photos of the current setup, it hasn’t changed much since last time:
Thank you very much for reading.
