Tweet-a-Watt now works with Google Powermeter!

Pt 1047

Breaking news! Tweet-a-Watt now works with Google Powermeter! and all the code is up on github. Once you have the Tweet-a-Watt working with the python scripts we provide, you can add a cool extension and have beautiful graphs generated thanks to Google Powermeter! This code, based on the original Tweet-a-watt, was created by the super-rad Devlin Thyne as special project with Adafruit (you can get a kit here).

You can download it from our source repository on github which now includes this script Please note that this mod is new, and is still under development, if you are having difficulties, try posting to the forums. Right now its only tested to work with a single Tweet-a-watt.


Google did release an API a few weeks ago, so this how it’s all working. Unfortunately, Google ignored our requests for access, choosing only to work with commercial partners and not the hundreds (perhaps thousands) of Tweet-a-watt makers out there, we’re excited that anyone can now build their own power meter and have it work with Google Powermeter now. Hopefully someone from Google will read this and consider adding Tweet-a-watt as an official option (besides AlertMe, UK and TED, Energy Detective, US). We’re open source, we’re power metering that works, we’re a good option for many people who wish to share their power usage.


For those interested in all things “net connected power meter” related, here’s a brief history on the Tweet-a-watt and what we’ve been up to. You can see all of these via our Tweet-a-watt blog category too.

Tweet-a-Watt is a DIY wireless power monitoring system. The project uses an ‘off the shelf’ power monitor called the Kill-a-Watt and adds wireless reporting. Each  plug transmits the power usage at that outlet to a central computer receiver. The receiver can then log, graph and report the data. This pack contains nearly everything* necessary to build a single outlet monitor and receiver. To monitor additional outlets, you will need an add-on transmitter pack. One outlet can monitor up to 1500 Watts.

The starter pack contains:

  • 2  XBee modules (one for receiver, one for transmitter)
  • 2  XBee adapter kits (ditto)
  • 1  USB FTDI cable (for updating, configuring and receiving data from XBee)
  • 1  bag of parts including 10,000uF capacitor, 220uF capacitor, 2 1% 10K resistors, 2 1% 4.7K resistors, 5mm green LED, 6″ rainbow ribbon cable, and 2 pieces of 1/8″ and 1/16″ heatshrink


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
