Grüßgott,
1.) Habe vor 2 Tagen iobroker auf mein Raspberry Pi 4 installiert. (Minimal image von 2019.11)
2.) Alles upgraded
4.) I2C enabled (raspi-config), RPi restarted, installed:
sudo apt-get update
sudo apt-get install i2c-tools libi2c-dev python-smbus
- i2cdetect -l << kann die Busse schön listen:
pi@hv:~ $ sudo i2cdetect -l
i2c-1 i2c bcm2835 I2C adapter I2C adapter
i2c-7 i2c i2c-tiny-usb at bus 001 device 014 I2C adapter
3.) Gab kommand:
sudo usermod -G i2c iobroker
Trozdem, findet dieses Adapter nicht mal den Bus:
