Trying to get a date with Plugwise

Having Plugwise in my house since December 2008, playing around with Digi Series 2 XBee modules for some time, knowing both are Ember EM250 based; nice ingredients for some fooling around with those two. I’ve already been asked a few times if I could ‘see’ any Plugwise traffic or other signs of the Plugwise network. No, i did not. Cause that would be wrong, if those would interfere that easily. And to tell you the truth, i wasn’t really interested enough to spend much time on this.

But why not try it some time? It has been on the to-do list for some time, but never made it to the top-5. But when there was another question recently from someone for whom i gladly spend lots of time without any personal gain or interest, i decided to try some things to see if a first small step could be made. I put 1 of my spare XBee modules into a XBee adapter, loaded the firmware version 2864 (XB24-ZB End Device AT), set the preconfigured PAN id to 0 (which means the XBee will join any PAN it can find) and uploaded the new configuration.

Now there’s this small green LED on the adapter labeled as ‘ASC’, which tells you the associated state of the XBee. When it starts blinking rapidly, you know you’re going in the right direction … reading back the Operating PAN ID from the XBee showed me a value like D6F0000134567. Hey, where have i seen that value before? It looks like a Ember MAC address.. YES, it’s the MAC address of my Circle+ ! How odd… ๐Ÿ™‚

OK, i know. This is just a very small step; i know the PAN ID of the Plugwise network now; duh. Next thing to figure out is the encryption key; it’s time to join forces on this project that is in the top-5 now and is there to stay!

Plugwise still sucks in some perspectives, but this is nice. And i have no idea if this will ever come to something useful. But that doesn’t matter, just as long as I’m having fun with what I’m doing ๐Ÿ™‚
