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?
