Tweeting power usage to Twitter


New York, NY, U.S.A. — (METERING.COM) — February 13, 2009 – Using off-the-shelf hardware, a Kill-a-Watt(TM) power meter has been modified to “tweet” (publish wirelessly) total daily kWh consumption to a user’s Twitter account.

The Tweet-a-Watt, as it has been dubbed, uses a “super-cap” to slowly recharge itself, according to Limor Fried of Adafruit Industries and Phillip Torrone of MAKE magazine. Once there is enough power it turns on an Xbee wireless module which transmits the data to a nearby computer (or an internet connected microcontroller). Once the power usage for the day is recorded it uses a predefined Twitter account – one’s own or someone else’s – to publish daily kWh consumption for the day. Multiple units can be used for an entire household.

The Tweet-a-Watt, which is still under testing, is one of the entries in the forthcoming Greener Gadgets Design Competition at the Greener Gadgets Conference on February 27, 2009.

The intention is to release the device as an open source hardware project, enabling anyone to make, modify and commercialize it.
