Tony Northrup, a Boston-area network security consultant and technology author, developed his interest in home automation after renting an apartment where every light was controlled by pulling a string. Tony turned to home automation products to add light switches without needing to hire an electrician or cutting into the drywall. Tony later bought a house and now uses computers to control and monitor virtually every system in his home: electrical, home theater, security, and even plumbing. Tony's wife, Erica, ensures his home hacking projects are user-friendly and reliable, while his cat, Sammy, mangles every project within paw's reach.
