It is also made of V0-rated flame-retardant PC, ensuring safety and heat resistance in electrical installations. The app gives also access to advanced features such as timer, time schedule, cyclic on and random off or gradual lightning functions, ideal for simulating presence or automating daily routines. It also allows you to view the current status of the relay, force a status change via a rocker switch, and maintaining synchronisation between the physical and digital states of the device. It is compatible with Amazon Alexa and Google Assistant, allowing you to control the switch module with voice commands, integrate it into home automation routines, or check the status hands-free, without using your mobile phone. This relay switch can be shared with other users, grouped with additional devices, or linked to sensors, cameras, or smart plugs or sockets to create a complete home automation experience.
