Wireless Control Smart Switch for Electrical Appliances

The client requirement was to develop an IoT-based device, which can control the on-off of any electrical device at home by using wireless technologies. The device is connected to the internet via Wi-Fi, and access through the smartphone application.

We implemented the wireless controlled switch for all electrical appliances. Using a mobile phone interface, users can remotely control the appliances by turning them, on/off from anywhere at any time.

Features of the Application

• Control the home Electrical appliances from anywhere with your smartphone app.
• Real-time device status provided to App
• Turn on/off a gang of devices with one tap
• Set scheduled/countdown/loop timers to turn on/off at the specified time
• Triggered on/off by temperature, humidity, or other environmental conditions
