 ### 3rd Party Connections
 This script will listen for 3rd party (Web-only, not software port) IP connections and if detected will disconnect for a period configured in the config.ini file. After the period has lapsed, the script will attempt to reconnect. This is useful if you still want to use web/smartphone apps (such as Alarmin). Note that it takes about 20 seconds to disconnect after which you can try to connect to the alarm again.
