Enable I2c interface with the Raspberry Pi configuration utility:
```bash
# pi user environment: Enable i2c interface
$ sudo raspi-config
```
Select `Interfacing options->I2C` choose `<Yes>` and hit `Enter`, then go to `Finish`.
Install dependencies for use the `smbus-cffi` module and enable your _homeassistant_ user to join the _i2c_ group:
```bash
# pi user environment: Install i2c dependencies and utilities
$ sudo apt-get install build-essential libi2c-dev i2c-tools python-dev libffi-dev
# pi user environment: Add homeassistant user to the i2c group
$ sudo usermod -a -G i2c homeassistant
```
### {% linkable_title Check the i2c address of the sensor %}
After installing `i2c-tools`, a new utility is available to scan the addresses of the connected sensors, so you can see the sensor address:
```bash
$ /usr/sbin/i2cdetect -y 1
```
It will output a table like this:
```text
0 1 2 3 4 5 6 7 8 9 a b c d e f
