The Sonoff RF Bridge 433Mhz RF Smart switch for WiFi provides a better range when connecting to various smart home devices, as it acts as a bridge between them and your control unit. Here, one's control device will most often be one's iPhone or other smartphone that can be connected to it, or possibly Google Assistant.

It can be quite smart if you have many different Sonoff smart devices in the house, but where the range of your Wi-Fi or your smartphone is limited, so you have difficulty getting connected. Then a bridge like this is a good opportunity to increase the coverage, so that you get better control and connection.

In addition, this smart switch supports various functions that make it easier to control your smart home devices. It can be timers that turn devices on and off after a certain period of time, or other programmable settings that can be sent via a simple signal that this supports.
