Adding Zigbee Sensors to Apple Home via CUBE OS Matter Bridge

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, let’s 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

Check the compatibility of Zigbee Sub-devices on your hand:

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.

If you don’t have any Zigbee dongles currently, check this giveaway event:

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 :white_check_mark: Yes Humidity value display may vary
SNZB-03P (Motion Sensor) Detects motion events :white_check_mark: Yes May show as basic occupancy status currently
SNZB-04P (Door/Window) Shows open/close status :white_check_mark: Yes Excellent trigger performance
SNZB-05P (Water Leak) Displays “Wet/Dry” status :white_check_mark: Yes Instant alert on leak detection
SNZB-06P (Presence Sensor) Detects occupancy state :white_check_mark: 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 :white_check_mark: Displayed & responsive
Apple Watch :white_check_mark: Displayed & trigger available
HomePod mini :white_check_mark: 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.

:light_bulb: 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.

I have a problem with the SNZB-02 sensor and the TRVZB valves. Basically, if I set up an automation in Apple Home to turn the valves on or off when the temperature is below or above a certain value, it doesn’t work — the valves don’t change their state.

I just tested it on my side and the automation can trigger the TRV normally.
Could you please try tapping “Test This Automation” to see if it works for you?

If i Tap test automation it works properly, but if i set an automation and see if it works autonomously it doesn’t..

Can you try deleting the automation and setting it up again? I’ve encountered similar issues with Apple Home automation not triggering before, but waiting a while or recreating the automation often resolves the issue. If that doesn’t work, could you try setting up the automation directly in CUBE OS? This may identify any problems on the CUBE side.

Thank you, it seems to work fine now.
