PiFace Digital I/O (PFIO)

The rpi_pfio integration is the base for all related PiFace Digital I/O (PFIO) platforms in Home Assistant. There is no setup needed for the integration itself; for the platforms, please check their corresponding pages.

There is currently support for the following device types within Home Assistant:

Binary Sensor
Switch

Set the jumpers on the PiFace board for address 0 (JP1: 1-2, JP2: 1-2).

Using with the Home Assistant Operating System

Note that the PiFace Digital 2 uses the Raspberry Pi SPI port, which is disabled by default when using the Home Assistant Operating System. You must mount the SD card on another computer and access the boot partition on the card. Edit the config.txt file and add the line dtparam=spi=on to the end.

This should enable SPI when the Home Assistant Operating System is booted to access the PiFace Digital 2 board.

Binary Sensor

The rpi_pfio binary sensor platform allows you to read sensor values of the PiFace Digital I/O .

To use your PiFace Digital I/O module in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
binary_sensor:
  - platform: rpi_pfio
    ports:
      0:
        name: PIR Office
        invert_logic: true
      1:
        name: Doorbell
        settle_time: 50

Configuration Variables

ports map Required

List of used ports.

num map Required

The port number.

name string Required

The port name.

settle_time integer (Optional, default: 20)

The time in milliseconds for port debouncing.

invert_logic boolean (Optional)

If true, inverts the output logic to ACTIVE LOW.

Default:

false (ACTIVE HIGH)

Switch

The rpi_pfio switch platform allows you to control the PiFace Digital I/O module.

To use your PiFace Digital I/O module in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
switch:
  - platform: rpi_pfio
    ports:
      0:
        name: Doorlock
        invert_logic: true
      1:
        name: Light Desk

Configuration Variables

ports list Required

Array of used ports.

num list Required

Port number.

name string Required

Port name.

invert_logic boolean (Optional, default: false)

If true, inverts the output logic to ACTIVE LOW.
