Many of the smart devices will work continuously even if there is a power outage, those are the devices that operate on batteries, such as door locks, door sensors, Smoke sensors, Gas leak sensors, video Doorbells, etc. These devices will send push notifications to the mobile when their status changes. For example, if someone presses the calling bell on your smart video doorbell you will receive a call on your mobile and you can see and talk to the visitor on your doorsteps using Marrath Home APP while you are away from your home. The power outage will not reset the implemented configurations of the installed devices which means that there is no need for configuring the device again when the power returns to home. The smart home devices remember its configuration even though there is no power and when the power returns the devices will continue to work as usual.
