EnergyLogger is a simple, native, cross-platform application designed to take the place of the Python scripts developed for the original Tweet-A-Watt project. By providing a user-friendly GUI interface for monitoring and logging data from these wireless enabled meters, we hope to remove one of the barriers to entry when implementing this project for yourself.
In addition to tweeting daily usage statistics, EnergyLogger is able to:
- Log interval data to a CSV text file,
- Upload interval data using Google’s Data API protocol to a Google Doc spreadsheet for analysis by other Google Apps or for use by Google PowerMeter,
- Monitor energy usage and raise an alarm when load remains outside upper or lower limits for a user specified amount of time,
- and “Tweet” these alarms to a user’s Twitter account.
The data files created by EnergyLogger can be imported directly into EnergyProbe, our flagship energy analysis software delivering an inexpensive, powerful, wireless solution to record, understand and interpret energy usage which had previously cost many thousands of dollars.
The 802.15 wireless standard implemented in the XBee radios allows EnergyLogger to monitor up to sixteen separate Kill-A-Watt meters simultaneously. Data is collected approximately every 2 seconds, processed, logged and uploaded at user defined intervals.
The interface is simple to navigate, provides all the pertinent information at a glance and can be made to disappear into the system tray or menu bar, doing it’s job in the background while your computer is free to do other tasks.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
