Toggle Do Not Disturb
The AppleScript used in the workflow posted here stopped working in Yosemite.
I found a new AppleScript (on github) and updated the workflow accordingly.

When trying to connect my hub I get the following error: "invalid value, jason0x43.alfred-hue, for parameter, username". Occurs regardless of whether I tap the link button on the hub or not.
I had the same problem. I got it to work using the "Run Script" action (and selecting /usr/bin/osascript as the language) rather than using "Run NSApplescript".
