got the code, a big thanks. I will be look at the code this weekend and hopefully make use of it.

We actually now also have a full Java stack for interacting with the Zigbee Ploggs using a RESTful API. I does pretty much what you need in this case.
We want to opensource it soon but if you drop me a mail ( you can find my mail on http://www.guinard.org/ ) I’ll be happy to send you the source code alongside with instructions!

I am also developing a java interface for the Telegeis modules, Have just started and saw your post that you would be willing to share your code for performing.

a) scan for zigbee devices and build a class element for each
b) get the name of devices
c) get the measurements
d) send a JSON formatted message to a queue
e) sleep for xx secs
d) repeat step c->e forever

I was wondering is the offer still available as this would save me a lot of time?

thanks
Gary

Did you at some point encounter problems with detecting Plogg devices using Plogg Manager? I’m currently trying to setup a Zigbee network using Ploggs and Telegesis USB stick to monitor electricity usage on a bunch of computers. I followed all the instructions from the Plogg website to setup the USB stick as coordinator and Ploggs as routers, however the Plogg Manager cannot detect any Plogg devices. Any advice on that?

Thanks.

Not yet but we are currenlty doing that and still hoping to be able to opensource the whole in a while. We’ll post more about it here.

Example:

AT+SN
OK
FFD:000D6F0000224328
FFD:000D6F0000262B19
AT+UCAST:000d6f0000224328=v
+UCAST:00
OK
ACK:00
UCAST:000D6F0000224328=~~SW Version 1.70~~Unit friendly name = Scaldabagno~~PCB Build R
UCAST:000D6F0000224328=esistors DIO9=1 , DIO10=0 , DIO11=0 ~~Unit is Zigbee Enabled~~
UCAST:000D6F0000224328=- Unit is a configured as a router~~ – Current Pan = 31F4 unit
UCAST:000D6F0000224328= is router~~Zigbee echo is on!!!~~TickCount = 9741087 ~~~~~~>

2) I wrote a java program to monitor the installed devices. It is based on opensource java:

- rxtxcomm package, for serial port management
- jtopas-08 is a library to do lexical analysis and parsing of the strings received by devices
it performs the following steps:
a) scan for zigbee devices and build a class element for each
b) get the name of devices
c) get the measurements
d) send a JSON formatted message to a queue
e) sleep for xx secs
d) repeat step c->e forever

I decided to push the message to a queue to loosely decouple the monitor from the two clients used to produce data for web and graphical pictures.
Using a broker I can send one message to many indipendent client programs at the same time.
I used the free message broker that you can download by http://www.mqtt.org/
It has a small footprint (50k) and runs also on small low power consuming devices (NSLU2-unix).
I am improving the code and correcting some bugs, especially on the parsing side in the work spare time.
I can share the code with you without problems if you like.
Actually I installed the application on an artigo pc (http://www.via.com.tw/en/products/embedded/artigo/) that I choose because it’s powerful, low consuming (15W running, 5W standby) equipped with a 32 Gb SSD disk.

The Linux version is actually what we are working on right now, since our current version of the Ploggs Gateway is Windows only (we use a DLL provided by the Energy Optimizers crew…).
What did you actually use if I may ask? I mean what kind of wrapper do you use in Java for connecting to the Zigbee Ploggs. For the BT version we currently use an virtual serial port (rfcomm): http://www.guinard.org/~misterdom/2009/03/18/connecting-to-the-ploggs-using-bt/

Would be interested to know what you solution looks like because we ordered a bunch of Zigbee Ploggs a few days ago…

Ciao
Massimo

We are still working on it and should be able to publish the code in about two month from now. Stay tuned on this blog for more info.

I was wondering if you already published the prototype?

Thanks,
Jose

Sounds indeed like a promising project, slick and design! Rather crazy that their project has the same name…

Just wonder how open their system is, I’d like to have something open in my home for monitoring energy (e.g. based on the RESTful approach) rather than a close system working on my iPhone app only.

But it sounds like the competition is getting tough
Thanks a bunch for your comment!

Dom, you should have bought the domain before that guy got it, grrr!!

I wonder how much of the flashy stuff shown there works, and is really being sold… Looks like google energy thingie, be there fast with a nice design, but makes me wonder what’s behind the façade…

do you know this product?

Actually we are going to release the gateway and interface software on this website soon so stay tuned.

As for the details the gateway software is currently written in C++ and has a very small footprint but it uses a Windows DLL for bluetooth communication which means it has to be installed on a Wintel PC with BT capabilities.

What is the platform you use for the gateway (hardware and O/S):
Is it a standard Wintel PC with Windows XP or is it PloggZgb EAP gateway ?

Thank you
Yury
