INTRODUCTION

This is a simple Python utility for logging data from a [Watts Up? Pro] power meter. Documentation for the serial port interface for the mete. You can find the .pdf manual here

Other software capable of logging data on the Watts Up? meter are available for download from watts up?, and they sell a realtime version for Windows .

The program will by default assume the most common device name for Linux and OS X platforms, but the serial port device can also be specified with the command line option -p

The Watts Up? Pro uses an FTDI serial to USB adapter internally. If the driver is not already installed on your operating system, download the latest driver from the FTDI website.

The files and packages I used are here under FTDI foder

USAGE

In here there a

Basic command line to run an independent script is: ''' python wattsup.py -l -o sample.log ''' outputs: sample.log (this version requires numpy and matplotlib installed in your linux flavor)

Another way to run is by just using -l flag. It will output a default .log file ''' python wattsup_USB0.py -l ''' outputs: log0.out

wattsup_USB0.py will "ALWAYS" look only for the FTDI USB0 "ONLY". If run wattsup_USBX.py it will output logX.out and look only for the USBX port. If port is not enable it will not run.

run also wattup -h for full description

FILES

'wattsup.py': logs and display the data to console, and generates a simple real time plot 'plot.py': Simple plottin program for files already logged. 'wattui.py': Interface to power meter (this version still on beta testing). Click here for more information 'files.raw': Sample files generated from this program 'run.sh': simple script on bash to run multiple python files

TO DO

Working on multiprocessing to run multiple python scripts wattsup_USBx.py at the same time
Fetching data from internal storage from Watts Up? Pro
Cumulative display of energy used
Ask user for optiontial plotting for power(watts), current(amps) or volts(v).

REPORT (What I did so far)

Build from scratch a "mini server" to simulate the work load.
Install ubuntu
update packages
install FTDI drivers for WATTS UP PRO
created a git repository for all watts up pro
update python libraries: numpy and matplotlib sudo apt-get install python-os sudo apt-get install python-numpy sudo apt-get install matplotlib.pyplot
working on home/administrator directory
use multiprocessing in python to run 4 different python scripts at the same time create 4 different wattsup.py versions, each with a single port
Files used: wattsup_USB0.py using port /dev/ttyUSB0 in line 169(args.port=/dev/ttyUSB0), 179(message…) 204 (log0.out) wattsup_USB1.py using port /dev/ttyUSB1 in line 169(args.port=/dev/ttyUSB1), 179(message…) 204 (log1.out)
wattsup_USB2.py using port /dev/ttyUSB2 in line 169(args.port=/dev/ttyUSB2), 179(message…) 204 (log2.out)
wattsup_USB3.py using port /dev/ttyUSB3 in line 169(args.port=/dev/ttyUSB3), 179(message…) 204 (log3.out)
created run.sh and give permissions chmod u+x run.sh
