If I understand well, you're talking about this device :
But it looks like one can only plug 1 probe, and by the way, I can't
find simple temp probes.
The starter kit looks good
(http://www.ibutton.com/ibuttons/1921Kit.html) but the DS9097U-S09 has
no addressable 1-Wire chip onboard. And it seems it uses TMEX driver,
so I'm not sure mlan or mlan3 freebsd ports can read data from it.
Thermocron looks really good too
ProductDisplay?prrfnbr=2438&prmenbr=776) and is apparently supported by
usage: thermodl 1wire_net_name <output_filename> </Fahrenheit>
- Thermochron download on the 1-Wire Net port
usage: thermoms 1wire_net_name </Fahrenheit>
- Thermochron configuration on the 1-Wire Net port
So now, will TMEX driven hardware work on FreeBSD with mlan ? and does
anybody have experience pluging more than one temp. probe on the
DS9097U adapter family ?
