Install the S-MATE in the box of your existing switch and pair it with a compatible receiver, e.g., MINI R3 (sold separately). You get reliable and fast local control of lights or other devices via eWeLink-Remote, even during an internet outage.
The device works with 1/2/3-button switches – use one button to easily turn connected devices on/off, and the others to trigger scenes in the eWeLink app. Thanks to CR2032 power, it does not require a neutral wire, making it a great choice for retrofitting older installations.
Note: S-MATE requires a compatible switch/receiver (e.g., MINI R3), which is sold separately.
