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 is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal. LinuxMCE currently only monitors temperature but can be expanded easily.

OWFS [http://owfs.org/] 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.

Usage Information

1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal. LinuxMCE currently only monitors temperature but can be expanded easily.

Currently confirmed devices working

1-Wire Serial Adapter[1] Temperature sensor[2]

To setup

1. Go to Show devices tree->CORE and click on Create Child Device

2. Click Pick Device Template and find 1wire device template or use ID 2161. Click Pick Device Template

3. Under Core->1wire I had to select the serial port under COM Port on PC

4. From 1wire device click Create Child Device and pick Multilevel Sensor

5. In Multilevel Sensor fill in PK_FloorplanObjectType with Temperature and Port/Channel Number with your temperature sensors address

6. Save and reload router

7. You should now see the Multilevel Sensor status look like this ON/AUTO/AUTO/25 (16.56). With 16.56 degrees.

8. The sensor can now be added under Floorplan Wizard


NOTE: This page is currently a WIP and will be expanded when more information is available. Main thing that needs to be added is how to find the address of the sensors.
