The PebblyPi: A Smart Doorbell

PebblyPi

A Pebble smart watch, and a Raspberry Pi. They are a perfect match. This is probably what [Daniel] thought when he embarked upon his latest project, a smart doorbell called the PebblyPi (tip submitted by [Ben]).

The actual project is quite easy to implement. All you need really need is a Raspberry Pi, a switch, a resistor, and a Pebble Smart Watch (plus a smart phone). Using a simple Python script on the Raspberry Pi, button press notifications are sent to Pushover, which allows the notification to arrive on your smart phone (and thus your Pebble Smart Watch). Pushover is a very cool notification service for Android devices, iPhones, iPads, and your Desktop. The concept behind this project is great, and the fact that it is so simple to implement opens up many other possibilities for interfacing your home electronics with the Pebble Smart Watch (or even just your smart phone). The ability to create custom notifications on any of your devices using any internet connected system is amazing!

You could receive notifications from your absurdly accurate weather station, or even your soil moisture monitor. Have you used Pushover in any of your projects? The possibilities are endless!

Pebble watch hack makes it a home automation controller

pebble-watch-hack-home-automation

[Enrico] loves his Pebble watch, and recently had a chance to explore the code package used to customize its function. It turned out to be really easy to work with so he set out to make the Pebble watch into a home automation controller.

So far the two bits of hardware used in his experiments are shown in the image above. The watch itself serves as the controller, interacting with the Ethernet relay board seen in the background. The watch communicates via Bluetooth but you don’t have to know much about that thanks to the example files available from the repository. With communications taken care of he needed a menu system to access commands on the watch. Instead of coding his own he hacked a playlist into the built-in music menu. This allows him to switch the relays on and off again as if he were playing or pausing audio tracks. See it in action after the break.
