The Sonoff iFan04-H is a Wi-Fi controller designed to manage both your ceiling fan and light from a single device. It connects via 2.4GHz Wi-Fi, allowing you to adjust the fan speed between low, medium, and high settings or toggle the lighting through the eWeLink app. For those who prefer hands-free operation, it integrates with Amazon Alexa and Google Home for voice commands, while the included RM433 remote provides a tactile alternative that can be held or mounted on a wall. Built from white polycarbonate, the compact unit measures 116 x 55 x 26 mm and weighs 125 g, making it easy to tuck away during installation. It supports a wide input voltage range from 100-240V AC and can handle a maximum fan power of 2A. Depending on your bulb type, it supports up to 600W for tungsten lamps or 300W for LED options, ensuring compatibility with various lighting setups. To help you automate your home environment, the controller features versatile timer functions, including single, repeating, and countdown modes. This makes it a practical choice for people who want to ensure their fan turns off automatically after a certain period or follows a specific daily schedule without manual intervention.
