1-Wire
From LinuxMCE
In order for 1-Wire to be supported under LinuxMCE 1-wire device template is needed. Unfortunately it got lost somehow. Maybe totallymaxed / Uplink_ still have that device template in their sqlCVS
1-Wire has some nice and affordable Weather Stations, their price is around 80$ while EIB/KNX Weather stations are around 600€.
There is an oww project that provides Linux interface to the Dallas Semiconductor 1-wire weather station.
