I've looked through some tutorials.
My Goal was to directly attach Ds18b20 Sensors to GPIO4 and to read via a mount Point into IOBroker.
First of all, do the Setup were you enable correct Interpretation on Raspi:
modprobe w1-gpio pullup=1 modprobe w1-therm if all works well you make these Settings permanent by putting it into (old kernel versions)# /etc/modules w1-gpio pullup=1 w1-thermThe same functionality should be achievable by putting the following in /boot/config.txt or better (ubuntu) /boot/Firmware/usercfg.txt dtoverlay=w1-gpio,gpioin=4,pullup=on
I suggest doing this in the end, if eventually everythin works
Install owfs and owserver:
sudo apt install owfs owserver
You should see the page on <Ip>:2121
If you enable the line with Server: fake in the /etc/owfs.conf file you should see fake sensors on the webpage
Next Thing is wiring of the sensors. I'm not an expert. The following works for me:
Wire 4,7kOhm Resistor between 3,3 V VCC of Pi an GPIO4 Data Port
Wire VCC or + or red to 3,3V of the pi
Wire Gnd or - to Gnd on Pi
Wire Data to Pin 4 of Pi
If you query dmesg you should see something like:
[ +0.024838] w1_master_driver w1_bus_master1: Attaching one wire slave 28.01193a3da276 crc e5
[ +0.007224] w1_master_driver w1_bus_master1: Family 28 for 28.01193a3da276.e5 is not registered.
[ +0.007224] w1_master_driver w1_bus_master1: Family 28 for 28.01193a3da276.e5 is not registered.
install Iobroker Adapter owfs
