If you recall the old Thingshield, it was an arduino shield that let you connect your arduino project to smartthings, over zigbee. It makes for endless possibilities, allowing you to create any zigbee device you like, very simply. Unfortunately, smartthings stopped making the Thingshield a few years ago.
I believe I now have a replacement, called “Mona Lisa”, based on the cc2530 zigbee chip from TI. It can pass 16 character strings to/from a smartthings device handler to/from the cc2530 device, which then passes the strings to/from a simple serial port that you can connect to 2 pins on your arduino (or anything else, like even a computer with a usb -serial adapter). That’s basically all the Thingshield did.
On top of that, it can also have some functionality without being attached to an arduino (or any other device). It has four 3.3V digital outputs you could use to control other things, and four 12-bit analog inputs you can use to sense things. It’s also a zigbee router, to expand the reach of your network (with an optional external antenna too).
Here’s what it looks like at the moment. The import bit is all on that little daughter board. I’ll be making a different carrier board that’s smaller and fits an arduino (and without bodge wires :)).
And here’s what the device handler looks like. And the code for it.
Please let me know your thoughts!
