Featured Image Control Smart Fan Using Amazon Alexa Echo and Google Home Assistant

This guide shows how to connect and control any smart ceiling fan with Alexa or Google Home on Android and iOS devices. We will learn to operate them using voice commands for Echo/Echo Dot and Google Home/Nest Mini speakers.

What Is a Smart Ceiling Fan?

Smart ceiling fans are IoT devices that extend the capabilities of traditional electric fans by connecting them to nearby Wi-Fi networks. They can be controlled by a proprietary Android/iOS app or using app and voice instructions on Alexa and Google Home. This means that they can connect to Amazon Echo/Echo Dot and Google Home/Nest Mini speakers.

1. Install the Smart Ceiling Fan

The following is an unassembled smart ceiling fan. It usually has three or four blades (not shown in the picture), remote control, bottom cover, microcontroller, rods, and canopies.

Frequently Asked Questions

How do I convert my normal fan to a smart fan?

To convert a normal fan into a smart fan that runs with Alexa or Google Assistant, find and connect it with a microcontroller assembly which has the required temperature and humidity sensors. However, if you don’t need sophisticated fan controls, just purchase a smart Wi-Fi switch. It will at least turn on and off the fan device.

Are smart ceiling fans worth it?

Smart ceiling fans are a huge improvement over traditional electric fans due to sophisticated sensors that distribute cooled air more evenly across the room. That may help you save energy as you can optimize fan speeds based on ambient weather conditions, such as temperature and relative humidity.

As smart fans can pair with other IoT devices such as a smart bulb or smart air-conditioners, they can operate within predefined schedules and routines. You can switch these fans off or on from outside your home.

What are the disadvantages of smart fans?

At the moment, smart fans cost a lot more than traditional electric fans. They also require continuous access to Wi-Fi to operate smoothly with Alexa or Google Assistant. This can be a problem in locations with poor Internet access. However, you can turn them off or on as needed with regular switches too.
