💻 Product Overview
The SONOFF Basic R4 is a smart switch that also works as an eWeLink-Remote gateway, letting you add sub-devices and pair an S-Mate2 or R5 for two-way and local control. It keeps your lighting controllable through the app even when a traditional wall switch is turned off, so you can combine existing wall switches with app control. A built-in temperature sensor monitors the product's maximum temperature in real time to help prevent overheating problems.
