Raspihats Switch
The raspihats
switch platform allows you to control the digital outputs of your raspihats boards.
To use your raspihats boards in your installation, add the following to your configuration.yaml
file:
# Example configuration.yaml entry
switch:
- platform: raspihats
i2c_hats:
- board: DI6acDQ6rly
address: 0x60
channels:
- index: 0
name: Fan Office
invert_logic: true
initial_state: true
- index: 1
name: Light Office
Configuration variables:
- i2c_hats (Optional): Array of used I2C-HATs.
- board (Required): The board name.
- address (Required): The board I2C address, hex value.
- channels (Required): Array of used digital output channels.
- index (Required): Digital output channel index.
- name (Required): Friendly name to use for the frontend.
- invert_logic (Optional): Inverts the output logic, default is
False
. - initial_state (Optional): Initial state, default is
None
, can also beTrue
orFalse
.None
means no state is forced on the corresponding digital output when this switch is instantiated.
- channels (Required): Array of used digital output channels.
Directions for installing smbus support on Raspberry Pi
Enable I2c interface with the Raspberry Pi configuration utility:
# 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:
# 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
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:
$ /usr/sbin/i2cdetect -y 1
It will output a table like this:
0 1 2 3 4 5 6 7 8 9 a b c d e f
