2. Informações de segurança e notas importantes

• Desconexão de energia: Always cut off the power supply before installing or performing any maintenance on the device. Failure to do so can result in electric shock or damage to the device.
• Fiação: Ensure that the neutral wire and live wire connections are correct according to the wiring diagram. Incorrect wiring can cause malfunction or safety hazards.
• External Switch Connection: The S1/S2 terminals are designed for connecting a rocker light switch and operate with weak current for safety. Do not connect the neutral wire and live wire to S1/S2.
• Rede Wi-Fi: The device requires a 2.4GHz WiFi network for operation. 5.0GHz WiFi networks are not supported.
• Ambiente de instalação: Do not install the device in a metal junction box. Metal enclosures can interfere with the WiFi signal, leading to poor performance or disconnection.

4.4 Controle de interruptor externo

The MINI R2 allows you to retain the functionality of your existing rocker light switch while adding smart control.

• After wiring the external switch to the S1/S2 terminals, the physical switch can still control the connected light.
• This provides flexibility, allowing control via the app, voice, or the traditional wall switch.

5. Manutenção

• Keep the device clean and dry. Avoid exposure to moisture or extreme temperatures.
• Não tente desmontar ou reparar o dispositivo por conta própria. Consulte um profissional qualificado para obter assistência técnica.
• Regularly check for firmware updates in the eWeLink app to ensure optimal performance and security.

6. Solução De Problemas

• O dispositivo não está conectando ao Wi-Fi: Ensure your router is operating on a 2.4GHz frequency. Check that the WiFi password is correct. Move the device closer to the router to improve signal strength.
• Device offline in app: Verify that your home WiFi network is active and the device has power. Restart the device by cycling its power. If the issue persists, try re-pairing the device.
• External switch not working: Confirm that the S1/S2 wires are correctly connected and that the physical switch itself is functional. Remember, S1/S2 should only be connected to a weak current switch, not live or neutral wires.
• O controle de voz não responde: Ensure your eWeLink account is properly linked to Amazon Alexa or Google Home Assistant. Check the device name in the eWeLink app and use that name in your voice commands.
• Conexão intermitente: Avoid installing the device in metal junction boxes, as this can block the WiFi signal. Ensure there are no major obstructions between the device and your WiFi router.
