OneWire

#OneWire

This plugin provides support for the 1-wire network, gaining access to affordable devices.

#Supported platforms

For now, only Linux is supported, by kernel mode or OWFS mode. Kernel mode provides access to only a few devices, but is suitable without adapter (devices directly connected to a GPIO pin). OWFS mode provides access to many devices, but requires an adapter like the USB-adapter DS9490R (serial adapters also exist). Yadoms recommends to use OWFS mode.

#Supported devices TODO

#Kernel mode This mode requires that 1-wire kernel modules are enable :

sudo modprobe w1-gpio
sudo modprobe w1-therm

#OWFS mode This mode requires that OWFS tools are installed on your target. Here are the steps to install :

Install OWFS and Fuse :

sudo apt-get install owfs fuse

Edit OWFS configuration file :

sudo nano /etc/owfs.conf

Comment line "server: FAKE = ..." Uncomment line "server: ..." and set here your adapter Uncomment line "mountpoint = /mnt/1wire" Uncomment line "allow_other"

(Note : Ctrl-o to save the file, Ctrl-x to quit nano)

Edit Fuse configuration file :

sudo nano /etc/fuse.conf

Uncomment line "user_allow_other"

Create mount point :

sudo mkdir /mnt/1wire

Restart OWServer :

sudo service owserver restart

Start OWFS :

sudo owfs

Note : on Raspberry Pi, it seems to be necessary to disable kernel using Device Tree :

sudo raspi-config
select "8 Advanced Options"
select "A5 Device Tree"
set to "No"
