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