INSTANT ALERTS WITH VISUAL PROOF You don't miss important events — you know exactly when and how to respond.

Change security modes on a schedule, turn on lighting when motion is detected, shut off water in case of a leak, or control locks, gates, heating, and appliances. Automation scenarios run in the background — even without an internet connection — while you focus on your day.
