It sounds like you are saying that each app maker decides how they will present things.

I will try to get more information from CSA then.

Thank you for your time.

Hi Tony,

[quote user="tpitman"]Can you please point me to some information that explains how an app like the Smartthings App is supposed to determine what UI to use? How is it supposed to know that this is a temperature sensor with a value to display?[/quote]

As I said it is the smart home ecosystem manufacturer which Matters device type they support.

As long as your company designs matter-compatible devices which follow Matter specifications and pass CSA required certification. Your device can be added to any Matter compilable smart home system that claims support for this cluster type. For example, you can find Apple homekit supported Matter devices from Home app - Accessories - Apple.

If you have joined CSA, you should be able to access Matter-1.1-Application-Cluster-Specification.pdf. This document clearly defines the features, commands, and attributes of one device. The smart home ecosystem also designs a UI based on this specification.

Best regards,

Charlie

Yes, I have tried those.

In fact, my code was started as the light bulb example and then I added the temperature code from that tutorial.

Can you please point me to some information that explains how an app like the Smartthings App is supposed to determine what UI to use? How is it supposed to know that this is a temperature sensor with a value to display?

In the log output I can see the temperature value being generated every 300ms when it is on and nothing when it is off, so I know it is doing its thing.

It just isn't informing the UI of the Smartthings app that it is a temperature sensor because it the app is showing the same UI for the bulb / switch and temperature sensor as if it thinks the sensor is a switch.

[quote user="tpitman"]They both say it is because the device is not a certified device[/quote]

OK, did you try with light bulb and light switch samples before?

Best regards,

The link you gave is exactly the tutorial I followed to get to this point.

When I try to use Apple Homekit or Google Home, they both won't complete the provisioning process. They both say it is because the device is not a certified device. This makes sense because we are not ready to certify our device, so it isn't registered with the certifying company.

Samsung's app is the only one that gives the option to continue when it detects it is not a certified device.

What do I do now?

Hi Tony,

Could you try other ecosystems like Apple Homekit or Google Home? It may depend on the smart home ecosystem manufacturer which Matters device type and attribute they support.

I suggest you try Adding clusters to Matter application — nRF Connect SDK 2.5.0 documentation (nordicsemi.com) first to confirm if a temperature sensor device works on your testing platform.

Best regards,
