# eWeLink-Remote Sub-Devices
You can transform the CUBE OS into an eWeLink Remote Gateway, allowing integration of sub-devices like the [**S-MATE 2**](https://sonoff.tech/en-us/products/sonoff-s-mate-extreme-switch-mate/58) **or** [**R5**](https://sonoff.tech/en-us/products/sonoff-switchman-r5-scene-controller/58).
