This script replaces the old thermostat processor AppleScript. We renamed it variable watcher because it can be used for a variety of solutions rather than specifically for thermostat scheduling.
Download the script into the following directory:
/Library/Application Support/Perceptive Automation/Python3-includes/
Select the Plugins->Reload Libraries and Attachments menu item to make the script active.
The best example of usage of this script is described in the Advanced Thermostat Adjustment wiki page.
