Sonoff S-MATE is a fit for almost any switch type, such as pulse switch, rocker switch, and change your existing switch into a smart one.
S-MATE is battery-powered, so it does not require a neutral wire in the mounting box.
S-MATE can connect the ordinary 1/2/3-button wall switch, which acts as a remote controller.
One Sonoff MINIR4 can connect more S-MATE, and one S-MATE can be added to three MINIR4.
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.
** S-MATE requires at least one MiniR4 to work. This is not a standalone product.
After pairing with the MINI R4, the S-MATE can locally control the MINI R4 through the “eWeLink-Remote” signal and thus trigger other smart devices in the smart scene.
The S-MATE is suitable for almost any switch type, such as pulse switch or rocker switch, and can change your existing switch into a smart one.
The Sonoff S-MATE is the module that can transmit the “eWeLink-Remote” signal. We also name it “eWeLink-Remote sub-devices”. MINI R4 is the device that receives the “eWeLink-Remote”, and we name it “eWeLink-Remote gateway”.
