Reads data from a Current Cost EnviR display via USB port to a Linux machine and logs the data to a file. Also updates an RRDtool round robin database. Forked from Jack Kelly's Perl script: https://github.com/JackKelly/CurrentCostLogger which itself was… Based on Paul Mutton's excellent Perl script and tutorial: http://www.jibble.org/currentcost/ with modifications from Jamie Bennett: http://www.linuxuk.org/2008/12/currentcost-and-ubuntu/ Example graphs and more information at http://matt.blissett.me.uk/apps/current-cost/ ---------------- Dependencies ================ This module requires the Device::SerialPort Perl module. Install this using Perl's package manager: At the Linux command line, type: sudo perl -MCPAN -e shell And then type: install Device::SerialPort Alternatively, in Debian/Ubuntu: apt-get install libdevice-serialport-perl Also requires RRDtool: http://oss.oetiker.ch/rrdtool/ apt-get install rrdtool and Proc::Daemon apt-get install libproc-daemon-perl ---------------- Installation ================ The program can either be run directly: current-cost or installed as a daemon (on Debian) by copying 'init-current-cost' to /etc/init.d/current-cost and copying (and editing) 'default-current-cost' to /etc/defaults/current-cost. Graphs can be generated using 'update-power' or 'generate-graphs'. --------------- Data format =============== The data format of the data.txt file is: UNIX TIME WATTS DD/MM/YEAR HH:MM:SS TEMPERATURE The time and date is taken from the local machine, not the Current Cost (although the time is extracted from the Current Cost's output so it would be easy to use the time from the Current Cost rather than from the local Linux machine.) ----------------------------------- To import into Open Office Calc =================================== On the import, select “separated by tabs” and “detect special numbers”
