Hackaday’s own [Devlin Thyne] has been working with Adafruit to come up with a way to use the Tweet-a-Watt along with Google Power Meter. Back in March we put out the word that Google had unveiled the API for Power Meter and [Devlin] is the first we’ve heard of to come up with a way to use your own equipment with the service. You can build your own or use Adafruit’s kit and the data pulled from your energy use will be nicely displayed using the big G’s tools. Right now there’s only support for one Tweet-a-Watt but we’d image this will evolve fairly quickly into a much larger house solution. Head over to the Tweet-a-Watt code page to get the source files for this project.
Twitter has been used for lots of experiments, both useful and just for fun. [FIRESTORM_v1] sent in his project that falls under the useful category. When he wanted a way to monitor his server’s power statistics, Twitter was a logical choice. Similar to the Tweet-a-Watt, he wrote a script that posts messages from APCUPSd to a Twitter account that he follows, and gets the updates on his phone. [FIRESTORM_v1] documents all of the scripts he used and the steps to get your server up and tweeting.
[adafruit] wrote in to let us know that the Tweet-a-Watt is now available in kit form. While the plans have been available for a while, a kit is a welcomed addition. The kit doesn’t include the Kill-a-Watt monitor, but rather the XBee adapters and parts necessary to make it talk to your Arduino or computer. The kit is $90, while the Kill-a-Watt can be found for roughly $20.
The team behind the the Tweet-a-Watt/Wattcher just won first prize at the Greener Gadgets design competition. The device is a hacked Kill A Watt that transmits power consumption using an XBee. After checking out DVICE’s preview of the competitors yesterday, we’re happy to see a prototype win instead of just a concept sketch.
