Turning an Existing Light Switch into an MQTT Connected Smart Switch using a Sonoff Mini

In this video we use the Sonoff Mini to convert a traditional light switch into a smart switch that can be controlled by my existing home automation system over MQTT using Node-RED. We will be using a Sonoff Mini R2 and flashing the Tasmota firmware onto it using the Sonoff's built in "DIY Mode" and then installing it behind a retractive switch to control some smart light bulbs where the power to the bulbs is switched by a secret key switch.
