If I understand well, you're talking about this device :

https://store.ibutton.com/cgi-bin/ncommerce3/ 
ProductDisplay?prrfnbr=2531&prmenbr=776

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  
(https://store.ibutton.com/cgi-bin/ncommerce3/ 
ProductDisplay?prrfnbr=2438&prmenbr=776) and is apparently supported by  
mlan :

# thermodl
usage: thermodl 1wire_net_name <output_filename> </Fahrenheit>
   - Thermochron download on the 1-Wire Net port
   ...
# thermoms
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 ?
