O2 has inked a deal with U.S. telco company AT&T to bring its personalised home security proposition to the UK this summer. The partnership between the companies will see O2 use AT&T's Digital Life service, which integrates old and new devices around the home, along with smart thermostat maker Tado and other device makers. O2’s parent company Telefonica and AT&T Digital Life first announced a limited trial of AT&T’s home management and automation service in Europe last year.
