SONOFF 4CH Pro WiFi 4-channel relay switch

SONOFF 4CH Pro WiFi 4-channel relay switch.

The Sonoff 4CH Pro R2 is a module with 4 relays (switches) that we control wirelessly over a 2.4GHz WiFi network using a dedicated phone app. In addition, it can be controlled remotely with a 433MHz remote. Thanks to the smartphone app, we can control mains-powered devices from anywhere in the world, which allows convenient management of room conditions, such as lighting, electric heaters, fans or ultrasonic humidifiers. The Sonoff 4CH Pro R2 connects to your home WiFi network, enabling convenient control of devices through the eWeLink app, available for both Android and iOS. The app offers not only basic on and off functions, but also the ability to schedule actions, create time loops and control based on measurements. Thanks to this switch, you can simulate the presence of household members to discourage potential burglars. What is more, the Sonoff 4CH Pro R2 works with voice assistants such as Google Assistant and Amazon Alexa.
