HW-Q990B/Q995B: The app can control the sound mode, but I cannot find it in Smart Things capabilities

Hi, @proza!

OCF devices like the soundbar work at a plugin level (app) instead of an API level. This means the communication is ST App <> Physical device.

In this post (more details section), I included some info about how these devices work:

Get info from API

Welcome to the SmartThings Community, @Sdahl1234! This is the information we have so far by analyzing Jacob’s case. The team checked the profile assigned to the device (list of capabilities used), and they noticed the temperature and the other values are not available. They’re trying to investigate more about the root cause. More details To attempt to shed light on why some capabilities might show up in the ST app but not on the API side, the team shared these details: The phone client (ST app) uses OCF’s COAP protocol, which allows the physical device to define its resources (such as the temperature values). So, these values can be written there by the device and as a result, they can be displayed by the app. The APIs do not work via OCF, but, the profile is the manifest of what val…

There are other devices in the same situation, like Air Conditioners. That’s why I previously created a report to get more info about this but the team hasn’t replied yet.

I pinged the team again and mentioned your case, I’ll keep you updated.
