Matter Door Lock Controller example

Thanks, that's useful information. We indeed want to use commercial Matter ecosystems, but it is no problem to create a custom app to support this. I also see that Home Assistant already merged support for creating the bindings:

https://github.com/matter-js/python-matter-server/pull/1155

Then the main concern is still the lack of samples. I'm familiar with the template sample and the zap-tool to enable the clusters I need. However just enabling the Door Lock client cluster, doesn't give me the functions I need to send an unlock command somewhere.

Is there any information available somewhere?

Do you want to use both the Matter Door Lock and Matter Door Lock controller with the commercial ecosystem?

If yes, then it’s the controller that must bind the Matter Door Lock to the Matter Door Lock controller. Currently, this is possible on both Android and iOS, but only if you create a custom app. Neither the Apple Home app nor the Google Home app supports binding by default.

Here is an interesting blog post from Eve: https://matter-smarthome.de/en/products/matter-bindings-in-action-eve-thermo-control/

Node IDs are allocated randomly during the commissioning process.

Thanks Amanda for your response! An example use case would be a fully matter enabled keypad, that can send unlock-door commands with a pin-code to configured node ids.

How to configure these node ids is indeed not clear yet, it seems that the Matter Documentation about a Door Lock Controller doesn't say anything about it. That's why I'm looking for examples ;)

Hi,

Unfortunately, we do not have the out-of-the-box example. You would need to use the Template sample and enable the Door Lock client cluster by yourself.

One challenge might be to find the proper Device ID of the Door Lock, which can be solved in a few ways. Could you elaborate on more details of your use case?

Regards,
Amanda H.

I know, but I want to develop a device that is commissioned to a Matter-over-thread network and then will send (un)lock commands to other Matter devices (no BLE). Of course this can be done using a raspberry pi + python, but I need this device to be small, cheap and battery operated. So I hope it is possible to do this with a Nordic MCU

Now you can use custom commands to control lock. For example BLE connection (Nordic BLE UART example). It isn't correct but it can be solution while we don't have example of controller

Thanks for your input! I am familiar with the door lock examples. The issue is that I don't want to create a door lock device, but want to create a device that can control a Matter door lock. There is a certifiable Matter device type for such devices, called a "Door Lock Controller" (device type ID: 0x000B), as can be seen here:

https://github.com/project-chip/connectedhomeip/blob/master/docs/ids_and_codes/spec_device_types.md

The problem is that I cannot find a single example project for such a device. There is a million "door lock" examples, but no "door lock controller" examples.

Nordic docs about Door Lock: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/matter/lock/README.html

Also official demonstration using Linux and nRF 52/53 DK: https://youtu.be/9Ar13rMxGIk?t=1047&si=vZXx4lyhdcJcozUl

By the way don’t use Project-Chip documentation because it much harder to repeat. Use vs code + ncs

As console for logs I recommend to use nRF Connect for Desktop > Serial Terminal > VCOM1(it’s serial port)

You can run example in NCS (Nordic Connect SDK).
1. install VS Code
2. install nRF Connect Desktop
3. install add-on nRF Connect for VS Code
4. Install SDK and Toolchain
5. Create Application > Copy Example > Matter Lock
6. Setup Built configuration
7. First Build
8. Flash using ui or west flash -d

nRF54L15-DK Matter Over Thread start

if you want I can make video how to start this example
