Slave smart plugs

 

— sockets that are not able to work independently and are connected through additional equipment. In other words, such an outlet receives commands from the user and transmits information to him not directly, but through control equipment — for example, a master type outlet (see the relevant paragraph) or a special gateway for a smart home system. It makes sense to pay attention to slave models if you already have a control device or you plan to build a system with several smart sockets — the “1 main and several additional” scheme will cost much less and will be easier to set up than several separate master sockets . When buying a slave socket, you need to pay special attention to compatibility — different technologies can be used to communicate with master devices, which are not always compatible with each other.
