Command line utility to combine probe data generated by the iGrill 2™ Thermometer
This tool allows you to export the individual CSV files from the iGrill app and combine them into a single file with user-definable averaged periods. This results in much easier generation of custom charts and logs.
Interpolated data is added in additional columns for gaps in the collected data from the iGrill. This is handy when you're out of range for a moment, or Bluetooth decides to take a nap, or whatever. The "pure" data is still included, so you can choose what to graph. Interpolated data is generated by looking for the next recorded data point for the probe, then averaging the difference. While this should produce a perfectly straight line, in practice it does not, because the data is rounded to the nearest 0.1 for display.
Once installed, use the following steps:
- Create a new folder
- Download all exported files from your cook to the new folder
cd your/new/folderphp /path/to/combiner/combiner.php > output.csv- Unless you want to get fancy, that's it!
Don't get too excited, this is just version 1. This is more "ketchup AND mustard on your hot dog fancy", not "OMG caviar" fancy :)
By default, the output is combined into 120-second periods. To change this, simply provide an integer as the first argument to the script.
php combiner.php 600
This example would generate 10-minute periods. This would be useful for longer cooks.
To get your data combined without averages, use a period of 1.
php combiner.php 1
By default, the output will include the hour and minute, in a 24-hour format. That might be a problem for overnight cooks, for example, or if you specify a period shorter than 60 seconds.
To change the format, just specify a second argument to the script.
php combiner.php 120 H:i
- US date, 24hr -
'n/j/y H:i'(the quotation marks are important) - Hours, minutes, and seconds, 24h -
H:i:s
