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.

Alternatively, there is the One Wire File System (OWFS).

OWFS [1] is a Virtual File System that sets up the 1-Wire network as a 'Directory' of 1-Wire nodes, which contains 'Files' which can be read or written to. These files are the values related to the 1-Wire node - i.e. temperature, power. If it is a 1-Wire switch, rather than sensor a value can be 'written' to the file to toggle it.

With OWFS set up, may be a device template would be easy to implement ?

As well as temperature and weather monitoring - 1-Wire can be used to monitor Energy Use/Power in the home with a Current Sensor. Also C02.
