Remote Mains Switch with >100m range

I wanted the capability to switch a flood light fitted outside the garage from the Raspberry Pi. With the Raspberry Pi connected to the internet this would give me the ability to remotely switch this light on from anywhere in the world. I had a look at wi-fi enabled power sockets but none of them had the range I was looking for. This project shows how to use the Dual Remote Relay Tx & Rx to do this as this has a range well in excess of 100 metres.
