Bluetooth relay

I intend using Bluetooth relay switches for Home Automation using an arduino with an HC-05 or HC-06 for commanding these devices wireless, but after an afternoon of searching the web I did not manage to find a project using such remote relays neither a tutorial so I end up with making this appeal to the community to help me further.
Enclosed the images of both faces of such a relay.

Probably no surprise. This is an Arduino forum. You might expect to use an Arduino to control a relay, which is common enough. Bluetooth is merely a means for sending data to Arduino.
