Raspberry Pi zero

The 1 Wire Pi Zero from AB Electronics UK is a communication board supporting the 1-Wire® protocol designed for use on the Raspberry Pi Zero.  A 5V buffered I2C port is also provided on the board.  The 1 Wire Pi Zero can be securely fitted to your Raspberry Pi using our mounting kit pack.

Headless Installation with ssh:

    Download: https://downloads.raspberrypi.org/raspbian_lite_latest
    unzip the image and put in the img file on the micro sd card (for example):  dd if=2019-04-08-raspbian-stretch-lite.img of=/dev/sdb    (be care full that /dev/sdb is the sd card and not your own disk!!)
    mount the boot partition of the sd card (not /boot),  and do a touch of a ssh file, this will start the ssh daemon at startup: https://www.raspberrypi.org/documentation/configuration/wireless/headles...
    Set ssh at startup with raspi-config

    Setting WiFi up via the command line via raspi-config: https://www.raspberrypi.org/documentation/configuration/wireless/wireles...

    Also configure the i2c interface: raspi-config->Interfacing Options->P5

    Install the extra packages: apt-get install owfs ow-shell i2c-tools

    With the onewire board installed check if the i2c 1-wire device is active: i2cdetect -l  and i2cdetect -y 1, this will show something like this, see the 18:

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

    Configure the /etc/owfs.conf file: server: i2c = /dev/i2c-1:0  or server: i2c = /dev/i2c-1:ALL
    Start the owserver:   systemctl restart owserver
    owdir will show you the bus and any devices found:
