AT&T has been showing off and talking about its Digital Life home automation service for the better part of a year now, but after missing its March launch target, it’s finally making the service available in 15 markets this week. AT&T has been testing Digital Life in Dallas and Atlanta since last summer, and plans to have it available in 50 markets by the end of this year. Digital Life is similar to Verizon’s Home Monitoring and Control service, with the major difference being that AT&T’s solution doesn’t require a customer to have an existing wireless or broadband service plan with the company to purchase it. The service gives customers access to things such as a security system that is monitored 24/7; the ability to see live camera feeds from anywhere in the world; controls to adjust climate and door locks remotely; and monitoring for water leaks, as well as the ability to shut off water mains if such a leak is detected.
