Just spent a few days getting this working on my Pi  I am using it primarily as a media server - PI + WD 2Tb usb disc - uses 3w when disc spun down and about 10w when active low enought to leave on 24/7 I'm a complete Linux noob so its taken me a while to sort this - have a slightly different approach to ghubsch but like him I got the basic script from jibble.org (+credit) My Pi is running squeezeplug (based on debian wheezy IIRC) This is a headless setup and so I ssh in using putty Minidlna (serving videos mainly for the 3 kids tablets - using bubbleupnp + vplayer and their computers - using VLC) Apach2 + PHP5 I use a perl script to read the device and save the data to a RRD (round robin database) every 5 secs or so (total file size for 10 years data ~ about 1.5Mb  , the script also writes a little html file with the current power and temp to the webserver so I can check its running (changes every 5 secs).I have some cron jobs creating png graphs on the server (10min.3hr,6hr,12hr,daily) every minute or so. The data is also sent to cosm using the Net::Pachube module although its a lot less trouble using the wget method (Net::Pachube was a pig to install for a noob with loads of dependencies that neeeds manually installing - even though I had cpanminus installed)Was interested to notice that once the data flowed to cosm it started appearing in the currentcost dashboard again, noit sure whether sending the data to cosm every 5 sec is going to work long term but I will see https://cosm.com/feeds/12483 can post script if you are interested I am having a few issues keeping the script running in the background - sometimes when I terminate the putty session it decides to end - still investigating that |

Hi Galaxynik, I have also added to my script an update to a RRD database, but, I'm not generating graphs yet. I was thinking about to create a PHP web page to generate graphs on demand (just when I access the web page), because I thought that generating graphs frequently via a cron job would make an unnecessary load on the Raspberry. Do you notice the load of generating the graphs ? I'm running raspbian, also with a webserver (lighttpd, mysql and PHP), headless, to serve basically as my web server for my photoblog (as photography is my 'other' hobby!), and for currentcost. I have also a shell script to upload system information to Cosm.com (cpu load, free memory, net in/out traffic, etc.) https://cosm.com/feeds/69589 I can post the script also if anyone is interested. I'm running it from a crontab, just every 5 min (i think is enough!) As for running the perl script on the background, even after closing the putty session, i just use: > perl script.pl & (add an '&' after the command, to execute it in the background) Hope this helps with your problem. Regards, GHubsch |

Wow, you have made great progress, maybe it can be packed as a download ready to go on a formatted SD card with OS as my programming is very very rusty. It would be nice to just have the Pi as a stand alone unit as they are cheap enough (cheaper than the bridge) so is the Pi stable doing this? I actually have a weather station as well wonder if it would support this as well, my weather station uploads every min to the site? Bogget |
