Introduction: Physical + IoT Switch (2way Switch)

Cayenne ( is a web based service to quickly design ,prototype and commercialize IoT solutions.

Using Cayenne I have made a switch that can turn on/off a light using relay. The switching of device can be done through website or through mobile app.

The next part is where i have added two way switch to the relay and light setup.

Adding two way switch to this setup enables users to use their devices even if the internet connectivity is lost.

Two way switch is a fail-safe option to use your devices even if your internet of things goes down.

Note- You will be working with 240 volts supply so make sure you take all the precautions.
