Hi All,

I operate node #11000001 in Daytona Beach, FL. I recently upgraded the firmware in this node to version 110. I also downloaded Pixel_K’s graphing script, but alas, it required a few more edits than just the relevant paths to get working with my firmware version. Also, I did not want to run from cron. I wound up with a small wrapper script that samples the data every 60 seconds, and several edits to the code itself. Here is the wrapper script:

#!/bin/sh

radd(){
        /home/shogunx/Pix.sh
        sleep 60
        radd
}

radd

And here is the edited script. Note that data, graph and perhaps other paths will need to be updated for your local environment. As you can see, I simply placed these in a home directory, with the entire path defined in the variable. The IP address of the UradMonitor will need to be corrected for your network. I also changed the aspect ratio and size of the graph to better suit my needs, as well as outputting a temperature graph as well. Interestingly, the “cut” arguments specified the wrong data fields in my UradMonitor’s JSON output, so that had to be corrected as well.
