5.2.1. Wiring for Single MINI R3

Figure 7: Wiring diagram for a single MINI R3 (top left) and for one MINI R3 with multiple S-MATE devices (bottom).
For a single MINI R3 installation, connect the Live (L) and Neutral (N) wires to the input terminals. Connect the load (e.g., light bulb) to the output terminals (Lout and N).
5.2.2. Wiring for S-MATE with MINI R3

Figure 8: Wiring diagram for one S-MATE controlling three MINI R3 units.
When using S-MATE with MINI R3, the S-MATE connects to your existing wall switch and communicates wirelessly with the MINIR3. The L/L1/L2/L3 terminals on S-MATE are used as terminal blocks for easier installation; leave them out if not needed. The S-MATE does not require a neutral wire as it is battery-powered.
6. Operacija
6.1. Kontrola aplikacije (eWeLink)
Once paired, you can control your MINIR3 and connected devices from anywhere using the eWeLink app on your smartphone or tablet. The app provides real-time sync status of your appliances, allowing you to turn them on/off, set schedules, and monitor their status.

8. Otkrivanje problema
Evo rješenja za uobičajene probleme s kojima se možete susresti:

Figure 13: Common smart home challenges addressed by MINIR3 and S-MATE.
- Smart lights offline when the physical switch is off: This is a common issue with smart bulbs. The S-MATE solution allows you to keep your physical switch always "on" for the smart bulb, while the S-MATE sends commands to the MINIR3 to control the power, ensuring the smart bulb remains powered and online.
- No neutral wire in the switch box: The S-MATE is specifically designed for this scenario. It operates on battery power and communicates wirelessly with the MINIR3, eliminating the need for a neutral wire at the switch location.
- Smart switches do not match original decoration styles: By using the S-MATE with your existing physical switches, you can maintain your home's aesthetic while adding smart functionality.
- Uređaj se ne uparuje:
- Provjerite da vaša Wi-Fi mreža koristi frekvenciju od 2.4 GHz.
- Check that the device is powered on and in pairing mode (refer to the quick start guide).
- Make sure your eWeLink app and device firmware are up to date.
- Move the device closer to your Wi-Fi router during pairing.
- Daljinski upravljač ne radi:
- Provjerite svoju internetsku vezu.
- Check the battery level of the S-MATE.
- Ensure the MINIR3 is online in the eWeLink app.
