SONOFF S-Mate

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 MINIR3 can connect more S-MATE, and one S-MATE can be added to three MINIR3.

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 MiniR3 to work. This is not a standalone product.

LoA and Icasa approved.
