How Should ST Architecture Handle Composite Devices?

Yet another example of the composite device debacle…sigh

Matter - smart home connectivity standard (formerly Project CHIP)

Ok, doing a little research, it looks to me like an air purifier and an air quality sensor are two separate device types. I suspect you’re running into the dreaded composite device issue where the combination of different device types used in a single device requires an explicit fingerprint definition for that combination in the driver. The thermostat driver was selected because it matches the generic device type fingerprint for the matter-thermostat: - id: "matter/air-purifier" deviceLabel: Matter Air Purifier deviceTypes: - id: 0x002D # Air Purifier deviceProfileName: air-purifier-hepa-ac-wind If you go to the API Browser+ and look at the device details for the device, I suspect there will be (at least) two device types in the fingerprints (0x002D for air purifie…
