Serial is Dead, Long Live Serial

February 25th, 2008

While looking for the holy grail in home automation protocols, I made a little discovery, a bit of kit called a Connect ME made by Digi. What this bit of hardware does is give you an over-sized RJ45 plug (or wireless antenna) and built into it is an embedded OS with development kit, now your probably asking “And?”, well here’s the thing in home automation, most of it can be interfaced via serial/RS-232, which is one of the things the Connect ME has connectivity for (as well as GPOs), so that “Service Port” on the back of your TV/AV Amp may just have another use, X10 / DMX / 1-Wire are some of other protocols made accessible.

So what do you do once you’ve hacked up all of the hardware needed to control everything? Start writing the software to interface with it should be a good start, now you don’t really wanna mess this up as your going to be doing it for lots of different devices, but all with the same hardware constraints, so no nice flashy web interface for this little device, course there is, make the web front-end a back-end, make it a web service and provide an interface that uses it, across all of your home automation devices. Hook the devices up with Zeroconf and they can be auto-detected by your interface, plug and play automation, once you build it and code it.

Now I know you could setup something like this using SNMP but come on where’s the fun in that?

So I guess the title of this should have been “Serial has gone 2.0”?
