# Plug - SONOFF S40

Earlier in the community, we explored how to add the [**SONOFF TX Switch**](https://cube.ewelink.cc/blog/add-your-devices-into-apple-home/switch-sonoff-tx) to Apple Home through the **CUBE OS Matter Bridge**, showing how switch-type devices work seamlessly with Apple's ecosystem.

This time, let's see how it performs with a **plug-type device** - the [**SONOFF Wi-Fi Smart Plug S40**](https://sonoff.tech/en-us/products/sonoff-iplug-series-wi-fi-smart-plug-s40-s40-lite/58) - to check how well it works inside Apple Home.

## Apple Home Experience <a href="#id-3e4741c2" id="id-3e4741c2"></a>

Control works smoothly across all Apple platforms I tested:

Response time is fast, and the state updates are almost instant. Turning the fan on and off feels natural and reliable through Apple's interface.

## Summary <a href="#eb6b589f" id="eb6b589f"></a>

The SONOFF S40 works perfectly through the **CUBE OS Matter Bridge**, just like the TX switch - stable connection, low latency, and full Apple ecosystem support.

If you have other plug-type or energy monitoring devices, give them a try and share your results below. It's exciting to see how many older Wi-Fi devices can get a second life inside Apple Home with CUBE OS.
