It's a pretty slick system-on-a-chip. So in theory it should work with any DASH7 chipset, like a CC430 not in a watch... though they are just now coming on the market. You should be able to go straight from the watch to an other CC430 system-on-a-chip connected to a relay that can handle the amps of your lights, or whatever you want to turn on and off... and for only about $15 or so No Arduino, no PC, no Processing... (But some coding of the TI microcontroller which I'm hoping is not too gnarly.) Thanks for the blog post! The watch is using a fairly new Dash7 protocol:

Are you going to post a link on the chronos wiki? The RF on the chronos isn't necessarily limited to communicating with only other TI RF chips, but the frequency, modulation scheme, and protocol stack all have to be compatible. It would take some experimentation to see what else it could talk to. There's a big advantage in routing all commands to a PC first because it can control more devices remotely and apply some logic instead of a single point point to point link between the watch and a light.

Just might require a little reverse engineering of the protocol? If what you said turns out to be true then I shall not waste my money on the 433MHz version TBH I probably wouldn’t attempt that anyway, my intention was to communicate between the watch and an AVR MCU using the generic 433MHz things, not directly with the light and watch, that should surely be possible?

It HAS to be a specific or specific series of RF IC's from TI. So even getting the 433Mhz watch and trying to get the lights to operate without that intermediate RF component, will be hard/impossible to do. Check with TI or some other place before you really try out various RF Tx/Rx. I'm about 85% sure that it wont work. Good luck !

Chronos -rf-> PC --> arduino -rf->lights Is that correct ? I think i just figured the answer to my question…

Chronos -rf-> PC –> arduino -rf->lights

Is that correct ?
