4. Operating Instructions

After successfully pairing the S-MATE with an eWeLink-Remote gateway device like the MINI R3, you can utilize two primary control methods:

• Local Control (No Internet): The S-MATE can directly control devices built into the eWeLink-Remote gateway even when there is no internet connection. This ensures basic functionality remains available.
• Smart Scene Control (With Internet): When a network connection is available, the S-MATE can activate other smart devices through predefined smart scenes in the eWeLink app. This allows for complex automation and integration with your broader smart home ecosystem.
