This project is based off of two projects and bringing the results to the Beaglebone Black. The first project is Tweet-a-Watt. This takes a signal from a Kill-A-Watt power meter and reports it to a host computer. The second one is RaspiWatt. This modified the first project in order to use a Raspberry Pi instead of a general purpose computer.
This should be fully working but I am having issues getting a working Beaglebone to test it.
What needs to be implemented is the cleaning up of the code to eliminate unnecessary things such as the pi plate code.
Give step by step instructions on how to install your project.
- Follow the hardware instruction up until the end of making the transmitter.
- Then download the software
- Set up a Cosm account
- Wire the XBee to the UART pins. (How do I do this? Show pictures.)
- Modify the Wattcher.py to use your account and the UART as the serial port
Plug the Kill-A-Watt in and the appliance into it. Make sure the red light is on the XBee and fire up COSM. (How do I fire up COSM? More details are needed.)
Theory of Operation
The Xbee has a A/D converter on it that transmits the current and voltage over the serial port on the Beaglebone. The python script takes the serial information and calculates the power then sends the data to COSM.
I soldered the kit together and changed the script to use the UART port on the bone.
I need to clean up the code so that the specialized Raspiwatt code is gone.
I think that this project didn't really require a lot of work outside of assembly. I didn't have to modify a lot but I think that I learned a lot working with the open source code and adding a little bit to it to work with an additional platform.
