Using rrdtool to chart Indigo data

Indigo currently shipping version 7 is a leading Mac home automation software package. One of it’s mostly widely-used features is its ability to execute user-provided Python scripts of AppleScripts. In my previous introduction to scripting Indigo with Python I showed how to use the Indigo plugin host to execute Python scripts. In this post, I’ll describe how I use a third-party charting package rrdtool to graph data from Indigo by taking advantage of Indigo’s ability to execute arbitrary Python scripts.

AppleScript and iTerm2

Among the many reasons I use iTerm2 in lieu of the macOS Terminal is its AppleScript support. I recently had the need to automate some tasks on my Amazon Web Services EC2 server in a way that takes advantage of iTerm2 AppleScript functionality. Use case I’ve found recently, that my screen sessions were disappearing. Although I haven’t completely excluded other causes, some have suggested that infrequently-reconnected sessions can be cleaned up.

Import and tag with Hazel and DEVONthink Pro Office

Hazel and DEVONthink make a great pair as I’ve written before. Using AppleScript, it’s possible to take the import workflow even further by tagging incoming files automatically. Use case I download a lot of mp3 files containing pronunciation of words in a language I’ve been learning. I keep a record of these words and tag them appropriately using my hierarchical tagging system. I’d like to download the files to a directory on the desktop.

Waking the computer to allow AppleScript to run.

I have a number of AppleScript applications that need to run at odd times. These maintenance tasks often attempt to run while the computer is sleeping. Particularly those that rely on UI scripting do not function during this period. This most flexible way of dealing with this is to manipulate the power management settings directly via the pmset(1) command. The variety of options available using pmset is staggering and beyond the scope of this post.
