Roberto, It seems to be the problem that it all sounds great but there is very little hardware out there. I was hoping some of you might have seen more hardware.
This all started as a smart RFID tag system for the military. It seems like it could be so much more, with the longer range, easy location sensing and the like. It doesn't seem to be mature yet and it doesn't seem set up for hacking like xbee or lowpan are today. I just think the idea that you could put thermostats in the rooms with this built in, then have a tag people carry around and it knows who's where and does all the right things is so good. I would pay a good chunk of money to have a setup that worked like that. Most of the current automation systems are far short of this. I am pretty sure I can make a thermostat out of the TI chip that has the radio and the LCD controller built in. I'm going to drop the thread now. jerry On 01/28/2014 04:20 PM, Roberto Spadim wrote: > hum found some nice links about dash7 > > http://www.fritz-hut.com/2013/01/04/home-automation-using-dash7/ > http://sourceforge.net/projects/opentag/ > http://www.ti.com/lsds/ti/microcontroller/16-bit_msp430/new-cc430.page?DCMP=CC430&HQS=cc430 > http://www.dash7.org/ (obvious) > > anyone found some sensors dash7 based? > > 2014-01-28 Roberto Spadim <[email protected]>: >> if anyone have the link to buy the hardware i could buy and leave a >> virtual machine online to test >> >> 2014-01-28 Paul Alfille <[email protected]>: >>> Very interesting. >>> >>> You're right, we could just add it to owserver We'd just implement the >>> owserver messaging protocol, which is also message based. >>> >>> Is there a trial platform?
