The Tweet-a-Watt kit 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.
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.

I love this! I’ve been building a xbee/arduino weather station for awhile now and feel guilty every time I leave the computer on to collect data when I’m not using it. However, for better or worse, my access point is almost always on so that is the perfect place to put a task like this!
Incidentally, this project makes me want to make a URL (REST api) available on thinggo.com to allow posting of tweetawatt data and subsequent viewing of status and history. Of course, that means I want to build a tweetawatt too…
If I write the code behind the URL/REST API to grab and display the updates is anyone interested in updating wattcher.py? An interesting side effect of this addition to thinggo is that “households” or “tweeters” will be connected to locations which can be viewed sorted by distance from any location…
