Raspihats Binary Sensor


The raspihats binary sensor platform allows you to read sensor values ​​using the digital inputs of the raspihats boards.

Configuration

To use your raspihats boards in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
binary_sensor:
  - platform: raspihats
    i2c_hats:
      - board: DI6acDQ6rly
        address: 0x60
        channels:
          - index: 0
            name: PIR Office
            invert_logic: true
            device_class: motion
          - index: 1
            name: PIR Bedroom

Configuration Variables

i2c_hats

(list)(Optional)An array of used I2C-HATs.

board

(string)(Required)The board name either Di16, Di6Rly6, DI16ac or DI6acDQ6rly.

address

(string)(Required)The board I2C address as HEX value.

channels

(list)(Required)Array of used digital input channels.

index

(integer)(Required)Digital input channel index.

name

(string)(Required)Friendly name to use for the frontend.

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
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- 23 -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 -- -- -- -- -- UU -- -- -- -- -- -- -- -- --
