My Review: Aqara Spatial Multi-Sensor FP400

From the user manual:

“The device also supports direct addition to third-party Matter platforms by scanning the Matter code on the device itself without going through configuration in the Aqara Home app. However, in this way, it can only be used as one general presence sensor and one light sensor. It is recommended that users configure the device through the Aqara Home app before synchronizing it to third-party platforms to use the device’s full functionality.”

Is there a technical reason that the “pure” thread protocol without an Aqara hub is so severely limited? Or is the text just saying that the Aqara app is required but not an Aqara hub?
