Many thanks to everyone for producing the code, Sensimilla’s modifications got the script working but when I try to incorporate the rrd update command it fails, is this the correct syntax? -

rrdtool update powertemp.rrd N:$watts:$temp;

I made a modified version of the script which works with the CC128 which is rebranded as the E.ON energy monitor currently being given free with new accounts in the UK.

I’m not getting this working as yet .. no response, and am printing the $line out as per Paul’s example .. nothing. However, if I press the OK & down button, it goes a bit mental.
Would love to update his script to also post to Google Powermeter, but stuck at the first hurdle …

(Ubuntu 10.04).

Thanks

Just as a comment, instead of using CPAN to install the SerialPort module, you can, if you’ve got admin rights on the box, install it nicely with package manager:
package “libdevice-serialport-perl” offers the module with short description of “emulation of Win32::SerialPort for Linux/POSIX”.

Nick – you might want to comment out the if line and everything inside the nested brackets afterward, and just use a plain old print command to see if there’s any output – as Tomas mentioned the newer CC128 gives a very different output and the regex in the given script simpy does not match, and so outputs nothing at all.

im trying to get this to work on osx 10.5.8. i know perl quite well and the script appears to connect to whatever port i point it at, but no output. I can only assume that im using the wrong port or i need to pre-configure the port somehow?
thanks

Sorry, the regexp was filtered by this commenting function since it contained xml-tags. Hope you understand what I meant anyway…

There is another change needed to use the script on http://www.jibble.org/currentcost/.

The regexp has to be changed to

m! *([\-\d.]+).*0*(\d+)!

since the CC128 sends the temperature before the power not the other way around like the older devices do.

I had a lot of problems before I disabled the regexp and could see what was actually coming out.

Very useful thanks. I’ve just followed your procedure to set up reading of data from the new Current Cost model, the CC128. The only change needed was to use a baud rate of 57600 instead of 9600. Thanks.
