Authentic product, 7-day warranty on manufacturing defects, fast delivery across India.\"\u003e\n\n\u003ch1\u003eSonoff iFan04 Wi-Fi Ceiling Fan \u0026amp; Light Controller\u003c\/h1\u003e\n\n\u003cp\u003eThe Sonoff iFan04 is a smart home automation controller that enables wireless control of ceiling fans and integrated light fixtures through Wi-Fi connectivity, supporting both 2.4GHz networks and voice assistant integration. Building automation technicians and smart home installers use this device to retrofit existing ceiling fan installations with IoT capabilities without requiring complete rewiring or replacement of fixtures. It solves the critical problem of adding remote control and scheduling functionality to traditional AC-powered ceiling fans while maintaining compatibility with standard wall switches and existing electrical infrastructure.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Sonoff iFan04 operates as an in-line smart controller that intercepts the AC power supply to ceiling fans and lights, converting standard on-off control into multi-speed fan regulation and independent light dimming. The device uses a microcontroller-based PWM (Pulse Width Modulation) circuit to manage fan motor speeds across four distinct levels while simultaneously controlling the light circuit independently, all coordinated through a secure Wi-Fi connection to the eWeLink cloud platform or local network. The controller supports both 110V and 220V AC input specifications, making it universally compatible with residential installations across different regions.\u003c\/p\u003e\n\n\u003cp\u003eWhat distinguishes the iFan04 from basic smart switches is its dedicated fan motor control algorithm that prevents electrical damage from rapid switching cycles and includes soft-start technology to reduce inrush current stress on aging fan motors. The device integrates RF remote control receiver compatibility, allowing users to maintain physical control options alongside smartphone and voice commands. Its compact DIN-rail mountable design fits within standard electrical enclosures, and the neutral wire requirement ensures safe operation with proper ground reference for the control circuitry.\u003c\/p\u003e\n\n\u003ch2\u003eKey

and connecting the iFan04 between the existing ceiling fan wiring and power supply, respecting the neutral, live, and ground wire connections marked on the device terminals. The controller must be mounted in an accessible electrical enclosure or junction box with proper ventilation, as the internal relay generates minimal heat but requires air circulation. After physical installation, download the eWeLink application, create an account, and add the device by scanning its QR code or entering the 8-character PIN found on the device label. The app will guide you through Wi-Fi network selection and initial configuration, after which you can assign the device to a room, customize control icons, and set up automation routines.\u003c\/p\u003e\n\n\u003cp\u003eFor voice assistant integration, link your eWeLink account to your Alexa or Google Home app, and the iFan04 will appear as a controllable device supporting commands like \"Alexa, set ceiling fan to medium speed\" or \"Google, dim the bedroom light to 50 percent.\" The RF remote functionality works immediately after installation without additional configuration, providing a physical backup control method. For advanced users, local network control via the eWeLink local API enables integration with home automation platforms like Home Assistant or Node-RED, allowing custom automation logic independent of cloud connectivity.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan the Sonoff iFan04 control both fan speed and light brightness simultaneously?\u003c\/summary\u003e\n\u003cp\u003eYes, the iFan04 features completely independent control circuits for the fan motor and light load. You can adjust the fan to medium speed while dimming the light to 30 percent, or any other combination. The PWM circuits are isolated from each other, preventing electrical cross-talk and ensuring smooth operation of both functions without interference.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs a neutral wire required for installation?\u003c\/summary\u003e\n\u003cp\u003eYes, the neutral wire is mandatory for proper operation. The iFan04 uses the neutral as a ground reference for its control circuitry. If your ceiling fan installation does not have a neutral wire in the junction box, you may need to run a new cable or consult a licensed electrician to access the neutral from the electrical panel.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat happens if my internet connection drops?\u003c\/summary\u003e\n\u003cp\u003eThe iFan04 continues to function normally using the physical RF remote control and wall switch inputs. The device maintains its last known state and automation schedules are stored locally on the controller, so fan and light operations continue without interruption. Cloud-based remote access and voice commands will be unavailable until internet connectivity is restored.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use the iFan04 with my existing ceiling fan remote control?\u003c\/summary\u003e\n\u003cp\u003eThe iFan04 has a built-in RF receiver compatible with standard remote frequencies. If your original remote operates on a compatible frequency band, it may work directly. However, for optimal performance and full feature access, Sonoff recommends using the eWeLink app or a compatible RF remote. Contact our support team with your remote model number for compatibility verification.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum load capacity?\u003c\/summary\u003e\n\u003cp\u003eThe iFan04 supports a maximum combined load of 2000W for the fan circuit and 1000W for the light circuit, with a total system maximum of 2000W. Most residential ceiling fans consume 50-200W, and standard LED light fixtures consume 10-100W, so typical installations operate well within these limits. Always verify your fan and light power ratings before installation.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the iFan04 work with 110V and 220V systems?\u003c\/summary\u003e\n\u003cp\u003eYes, the iFan04 is dual voltage rated for AC 110V-240V input at 50\/60Hz frequency, making it compatible with both North American 110V systems and international 220V installations. The device automatically detects the input voltage, so no manual configuration is required.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
