5. Solução De Problemas
If you encounter issues with your BroadLink RM4mini, refer to the following common problems and their solutions.
5.1. Problemas de conectividade
- O dispositivo não está conectando ao Wi-Fi:
- Ensure your Wi-Fi network is 2.4GHz. The RM4mini does not support 5GHz or mesh networks.
- Verify your Wi-Fi password. It should not exceed 32 characters and should not contain special characters.
- Temporarily disable "Smart Connect" or similar features on your router if it combines 2.4GHz and 5GHz bands under one SSID during initial setup. Re-enable it after successful connection.
- Make sure your smartphone is connected to the 2.4GHz network during the device addition process.
- IR signal not reaching devices:
- Ensure there are no physical obstructions (furniture, walls, etc.) between the RM4mini and the IR-controlled appliance. IR signals require a clear line of sight.
