Multi-admin is one of the core features of Matter, as it provides for simultaneous operation in multiple smart home systems. Accordingly, family or household members could operate the device with the digital assistant or smartphone app of their choice. The last command given applies in each case. As an example. If a user has an Amazon Echo, a HomePod mini, and also wants to buy a Google Nest Thermostat. As long as the device supports Matter, he can add the device to both the Alexa and HomeKit ecosystems and even Google Home. Using any of them to control the device, the status will be synchronized to all ecosystems.
