You could say yes, or not exactly. Since Matter has Multi-admin function, Matter devices can be controlled by all Controller apps, which means users can control all smart devices with just one app. However, this app may not enable all the features of the device. Some advanced features may not be available to Matter, such as power consumption on the socket, and complex effects scenes on the light strip. Therefore, users sometimes still need to download the device app, such as the meross app to set advanced features.
