INFO="Orange/Raspberry PI Dallas DS18B20 temp sensor(s), get value(s), and send to Domoticz every 5 minutes"
#
# Created by ILoveIoT 2019
# 
# For console use     : /root/scripts/gpio/dallas.temp.reading.sh
# For background use  : /root/scripts/gpio/dallas.temp.reading.sh &
#
# Set in /boot/armbianEnv.txt 
# dtoverlay=w1-gpio 
# overlays=w1-gpio
#
# GPIO1 is used in this example for reading the Dallas DS18B20
#
# Use : gpio readall
# | Physical 12 | V1 | Mode IN | Name GPIO.1 | wPi 1 | BCM 110 |
#
# Uncomment/remove lines if you not using 4 Dallas device's
#


# Set the Domoticz server & port
SERVERIP="192.168.8.189"
