S-MATE can connect a regular wall switch with the 1/2/3 button, which acts as a
remote control. After pairing with the MINI R3, it can be controlled locally by
S-MATE via 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.
The S-MATE is battery powered, so it does not require a neutral wire in the
mounting box. S-MATE is suitable for almost any type of switch, such as pulse
switch, rocker switch and changes existing switch to smart switch. Once S-MATE
is added to any eWeLink-Remote gateway (such as MINI R3, M5, B05-BL), it can not
only control all eWeLink-Remote gateway products when there is no local network
connection, but also control any other SONOFF smart device in the smart scene
when there is a network connection. This is eWeLink-Remote control. Functions: ?
