S-MATE can connect the ordinary 1/2/3-button wall switch which acts as a remote controller. After pairing with MINI R3, MINI R3 can be controlled locally by S-MATE through the “eWeLink-Remote” signal, and trigger other smart devices in the smart scene. 1 MINIR3 can connect more S-MATE, and 1 S-MATE can be added to 3 MINIR3.
S-MATE is battery-powered, so it does not require a neutral wire in the mounting box. S-MATE is fit for almost any switch type, such as pulse switch, rocker switch, and change your existing switch into a smart one.
SONOFF S-MATE is the module that can transmit the “eWeLink-Remote” signal, We also named it “eWeLink-Remote sub-devices”.MINI R3 is the device with “eWeLink-Remote” received, we name it “eWeLink-Remote gateway”. Once S-MATE was added to any eWeLink-Remote gateway( such as MINI R3, M5), can not only control all products with eWeLink-Remote gateway when there is no network connection locally but also controls any other SONOFF smart device in the smart scene when there is a network connection. It is “eWeLink-Remote” Control, or you can click this post to learn more.
