[Enrico] loves his Pebble watch, as well as just recently had a possibility to check out the code bundle utilized to customize its function. It [turned out to be] truly simple to work with so he set out to make the Pebble enjoy into a house automation controller (dead link; Web Archive).
So far the two bits of hardware utilized in his experiments are shown in the picture above. The enjoy itself serves as the controller, interacting with the Ethernet relay board seen in the background. The enjoy communicates by means of Bluetooth however you don’t have to understand much about that thanks to the example files offered from the repository. With communications taken care of he needed a menu system to gain access to commands on the watch. instead of coding his own he hacked a playlist into the built-in music menu. This enables him to switch the relays on as well as off once again as if he were playing or pausing audio tracks. See it in action after the break.
