The CГApL∀b SmartPlug is a "smart" and utterly useless IoT power plug that tells you whether you plugged it in the socket or not. A companion Android app will inform you nearly real-time on any plugging changes, and of course, shit's tweetin' too, yo.
The SmartPlug is built around some ESP8266 based hardware with a C SDK firmware.
Optionally, a simple backend written in Python can be utilized for tweeting and sending status changes via WebSockets to the Android companion app. Alternatively, the firmware can be set up to use ThingSpeak for tweeting instead.
