1) yes, you should have dtoverlay=w1-gpio in your
config.txt and reboot.
2) you can get the id of YOUR sensor with ls -l /sys/bus/w1/devices
: the last numbers are the ids:
lrwxrwxrwx 1 root root 0 Mai 13 07:30 10-000802bf634d
-> 000802bf634d
Ok I've dtoverlay=w1-gpio
activ and I've rebooted but still no go. I've found that I can do
w1thermsensor ls
but I get Found 0 sensors:
My sensor is connected red on 5V, yellow on input #2 of piface digital and black on ground.
Input #2 is it ok or should I use another. My sensor is DS18B20 water proof with 3 feet cable. Once it is working I'll buy a small one.
When I launch pi_mqtt_gpio I get the following error
w1thermsensor.errors.NoSensorFoundError:
Could not find sensor of type DS18B20 with id 34c000000000
Please check cabling and check your /boot/config.txt for
dtoverlay=w1-gpio
Ok I got it . I've plugged the data cable of the sensor directly on the GPIO 4 under the piface. Now I have this
pi@phytopi ~ $ w1thermsensor ls
Found 1 sensors:
1. HWID: 0319a27966d7 Type: DS18B20
and this
pi@phytopi ~ $ w1thermsensor all
Got temperatures of 1 sensors:
Sensor 1 (0319a27966d7) measured temperature: 26.69 celsius
now I need to export it via mqtt to my HA
As this sensor is plugged directly into the GPIO4 of the raspberrypi and not on the piface, should I have more then one gpio_modules listed like this:
gpio_modules:
- name: piface2
module: piface2
- name: raspberrypi
module: raspberrypi
Or should I have two seperate gpio_modules: entry
gpio_modules:
- name: piface2
module: piface2
digital_outputs:
- name: valve_avant
module: piface2
pin: 1
on_payload: "ON"
off_payload: "OFF"
initial: low # low or high
...
gpio_modules:
- name: raspberrypi
module: raspberrypi
sensor_modules:
- name: ds18b20
...
Great it's working. Here is my config for piface relay control and ds18b20 sensor on the GPIO 4. I had to plug the data cable of the sensor directly on GPIO4 under the piface.

Thanks great software for my domotic
How do you get the address id for sensor in that module. I have a DS18B20 sensor connected to input 2 of my piface digital. I get
Should I have dtoverlay=w1-gpio in my /boot/config.txt ?
