Usage

OWFS Interface

First step is to setup the “One wire interface”. During the device setup it is required to enter the OWFS init arguments. Default arguments are “—i2c=ALL:ALL”, means OWFS is about to scan for one-wire bus masters on all I2C interfaces.

You can simulate one-wire device with following init argument: “—fake=10,22,28,05”

More about init arguments here: https://www.owfs.org

W1 Kernel Driver

Install the kernel driver w1. Raspberry Pi users can use rasp-config to enable ‘one wire’ which enables W1. There are not further steps necessary, temperature sensors will be discovered if the driver has been loaded successfully.

Requirements

• The package “nymea-plugin-onewire” must be installed.
