I took the approach that the Arduino should just publish xAP packets which contain the data of thing being monitored, and I have an xAP PACHUBE service that published that data to Pachube. http://www.dbzoo.com/livebox/hah_arduino http://www.dbzoo.com/livebox/hah#xap_pachube I modified the ENC28J60 library from jeenode so that UDP broadcast packets could be sent. This is what xAP uses. Interesting IDEA.

I am attempting to build a WIZ812MJ module into an ethernet shield, and am interested in knowing how your mods might be relevant in that scenario I’m not as smart as you obviously, do you have a diagram on what this circuit looks like?

I am currently looking at using the <a href="http://www.openkontrol.org/wiki/tiki-index.php?page=aProtocol+functions" rel="nofollow">aProtocol </a> as this is similar and perhaps a better standard. The aProtocol is based upon polling rather than node that transmit independently, this assumes the existence of a hub that has quite a lot of CPU power. I am considering if the functions of the hub can be split to provide more resiliance and enable arduinos to be used. John.
