Had an email today from Cosm announcing the switchover to Xively and also the desupport of the Cosm CurrentCost dashboard.

I suspect that this means that my PVOutput feed (which goes via NetBridge to Cosm to PVOutput) will stop working.

Anyone directly loading to PVoutput using a Raspberry PI reading from the Envir?

Hi,

I don't use the above scripts but I do have a number of EnvIR's in different locations and few geographically dispersed Raspberry Pi's.

I use node.js, so developed a small module that treats the basestation as an event emitter. The events I get out of this module are easier to process than the raw XML (imho). Short examples are provided. I'll be expanding these examples when time allows.

The events I get from the basestation are sent into 'redis' pubsub queues, where I can easily centrally process them and send them to other services (like cosm/xively or emoncms etc). Since I recently added the 'average' events and the 'filesystem' support I find that I get a wealth of nice information now.

Comments/feedback/enhancements welcome:

Packaged for npm on npmjs.org: https://npmjs.org/package/ccxmleventemitter

GitHub: https://github.com/TheDistractor/CCXMLEventEmitter

I hope someone else finds it useful.

Of course :)

Take a look at measureit. There is a pre configured pi image available too.

It grabs the data, store them in a database and display them in a website and shows some nice graphs. This is running on your pi.
You can send all data to pvoutput.org. Usage and creation data.

I have a python script that pulls updates from the currentcost using the pi's gpio serial tx, 3v and ground pins. Planning to do a 5 minute average and upload to xively.

I already have another script that's updating different stats to xively from the pi and has been since it was cosm.

Still running fine here - messed around with network so that raspi-pi had the wrong dns so after reboot wasnt updating clock using ntp so my script kept throwing fatals and exiting - only real problem
