Sonoff 4 Channel Wifi Smart Switch

The Sonoff 4 Channel Wifi switch is a cost effective method to be able to switch 4 appliances by using your smart phone from anywhere in the world. Sonoff sends data to cloud platform through the WiFi Router, which enables you to remotely control all appliances with the App eWeLink on your smart phone. Simple on off control or creating or a time based schedule is easy to setup using the eWeLink App.

Home automation is “The Internet of Things”. The way that all of our devices and appliances will be networked together to provide us with a seamless control over all aspects of our home and more.

One of the great benefits with the Sonoff devices is that they the schematic is published by the manufacturer (here) and this has allowed the “hacker” community to implement features that are not offered by the standard firmware. We have a number of projects planned for these versatile devices so please drop by an check what we are up to.

If you want to go beyond the standard Sonoff functionality and develop functions other than the simple on off control then consider replacing the factory firmware with some custom firmware. Visit the following tutorial https://randomnerdtutorials.com/how-to-flash-a-custom-firmware-to-sonoff/ and look at the following firmware projects:

Inventech is a solution development company and we often use commercially available hardware and adapt or customize it to a particular problem. This methodology has been successfully applied to a number of our projects and products. If your requirement extended beyond just simply switching off an electrical appliance, perhaps you want to provide a dashboard, or monitor an environmental variable and make intelligent decisions then contact us and learn how to adapt readily available technology to your project.
