# Sensor - SNZB Sensors

You've probably already seen how we've connected **switches, plugs, and lights** like the **SONOFF TX**, **S40**, and **B05-BL** to Apple Home through the **CUBE OS Matter Bridge** - all working smoothly and locally across Apple's ecosystem.

Now, it's time to explore how **sensor-type Zigbee devices** perform in Apple Home when bridged through CUBE OS.\
In this post, we'll walk through a hands-on test featuring the following SONOFF Zigbee sensors:

| Device                                                                                                       | Type                          | Function                    |
| ------------------------------------------------------------------------------------------------------------ | ----------------------------- | --------------------------- |
| [**SNZB-02P**](https://sonoff.tech/en-us/products/sonoff-zigbee-temperature-and-humidity-sensor-snzb-02p/58) | Temperature & Humidity Sensor | Measures ambient conditions |
| [**SNZB-03P**](https://sonoff.tech/en-us/products/sonoff-zigbee-motion-sensor-snzb-03p/58)                   | Motion Sensor                 | Detects movement            |
| [**SNZB-04P**](https://sonoff.tech/en-us/products/sonoff-zigbee-door-window-sensor-snzb-04p/58)              | Door/Window Sensor            | Detects open/close status   |
| [**SNZB-05P**](https://sonoff.tech/en-us/products/sonoff-zigbee-water-leak-sensor-snzb-05p/58)               | Water Leak Sensor             | Detects moisture presence   |
| [**SNZB-06P**](https://sonoff.tech/en-us/products/sonoff-zigbee-human-presence-sensor-snzb-06p/58)           | Human Presence Sensor         | Detects occupancy           |

## **Setup Steps** <a href="#etbag" id="etbag"></a>

Just follow the same steps as in the Getting Started guide:\
Power up your sensors → pair them to **CUBE OS** via a **Zigbee Dongle** → enable the **Matter Bridge** → scan the QR code to add everything into **Apple Home**.

All paired sensors will appear automatically under their respective categories.

## **Apple Home Experience** <a href="#odbal" id="odbal"></a>

Here's how each sensor type behaves inside Apple Home via CUBE OS Matter Bridge:

| Sensor                         | Display in Apple Home          | Automation Support | Notes                                        |
| ------------------------------ | ------------------------------ | ------------------ | -------------------------------------------- |
| **SNZB-02P (Temp & Humidity)** | Temperature shown in real-time | ✅ Yes              | Humidity value display may vary              |
| **SNZB-03P (Motion Sensor)**   | Detects motion events          | ✅ Yes              | May show as basic occupancy status currently |
| **SNZB-04P (Door/Window)**     | Shows open/close status        | ✅ Yes              | Excellent trigger performance                |
| **SNZB-05P (Water Leak)**      | Displays “Wet/Dry” status      | ✅ Yes              | Instant alert on leak detection              |
| **SNZB-06P (Presence Sensor)** | Detects occupancy state        | ✅ Yes              | May show as basic occupancy status currently |

## **Automation Example** <a href="#lc6qd" id="lc6qd"></a>

Let's create a simple automation to see it in action:

When the **SNZB-04P Door Sensor** detects the door opening → turn on the **B05-BL smart bulb** instantly.

The automation setup in Apple Home is straightforward, and the response is nearly instant.\
It feels just like using native HomeKit accessories - all **local, fast, and reliable**.

## **Summary: Sensor Experience in Apple Home** <a href="#fm74n" id="fm74n"></a>

| **Tested On** | **Result**                                        |
| ------------- | ------------------------------------------------- |
| iPhone / iPad | ✅ Displayed & responsive                          |
| Apple Watch   | ✅ Displayed & trigger available                   |
| HomePod mini  | ✅ Recognizes sensor triggers via Siri automations |

Overall, these SONOFF Zigbee sensors perform **surprisingly well** in Apple Home through the CUBE OS Matter Bridge - stable connection, minimal delay, and seamless integration with Apple's automation system.

💡 **If you're already running CUBE OS**, try adding your Zigbee sensors and see how they bring your smart home automations to life in Apple Home - no cloud, no YAML, just local control made simple.
