Are My Lights On Seattle


Are My Lights On is a simple server-side application that checks if an address is experiencing a power outage and can notify users by text or email.


This is a small project conceived on a windy night in Seattle.


Electrical outage can lead to failure of important systems in the home.  When this is the case, it is vital to know when a power outage is happening, especially while away.  Are My Lights on uses City of Seattle's service outage API and a location calculation based on AssemblySys' point-in-polygon algorithm to determine if a given address is experiencing loss of power.  If the power is out, the application will send a text or email message to the user.  When power is restored an additional notification is sent.  The application may be set to run at an interval using crontab on a Linux server and may be configured with multiple addresses and notification preferences.
