Get your ideal fan speed without having to reach for clunky pull chains with this Treatlife 4 Speed Smart Ceiling Fan Switch. This wall-mounted fan switch delivers hands-free voice control. Compatible with Alexa and Google Assistant, you can adjust your fan's speed and power when your hands are full. Use a simple voice command such as "Alexa, set the fan to 4." This voice-activated system is also convenient for children to adjust settings who cannot reach the fan itself. This smart home accessory also allows you to create timers, schedules, and countdowns to set your smart ceiling fan to automatically turn on or off at specific times. This ceiling fan control supports bluetooth configuration, but is not compatible with fans with a built-in remote control system. The maximum ceiling fan load is 1.5A to provide 4 fan speed, and this switch uses 2.4G Wi-Fi. A neutral wire is required in the wire box. Add an additional layer of control and comfort to your smart home system with this 2 pack of Treatlife 4 Speed Smart Ceiling Fan Switches.
