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	Temperature & Humidity Sensor	Measures ambient conditions
SNZB-03P	Motion Sensor	Detects movement
SNZB-04P	Door/Window Sensor	Detects open/close status
SNZB-05P	Water Leak Sensor	Detects moisture presence
SNZB-06P	Human Presence Sensor	Detects occupancy

Setup Steps

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

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

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

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.
