homebridge-switch-piface

Description

With this plugin, you can create switches that will control Piface outputs.

This fork is adapted from homebridge-dummy.

Example config.json:

    "accessories": [
        {
          "accessory": "PifaceSwitch",
          "output": 0,
          "name": "My Switch"
        }   
    ]

Installation

On a fresh installation you should enable SPI.

Therefore start raspi-config -> Interface Options -> SPI -> Yes.

Reboot the RPi.

Stateful Switches

The default behavior of a switch is to turn itself off one second after being turned on. However you may want to create a switch that remains on and must be manually turned off. You can do this by passing an argument in your config.json:

    "accessories": [
        {
          "accessory": "PifaceSwitch",
          "output": 0,
          "name": "My Stateful Switch",
          "stateful": true
        }   
    ]

Reverse Switches

You may also want to create a switch that turns itself on one second after being turned off. This can be done by passing the 'reverse' argument in your config.json:

    "accessories": [
        {
          "accessory": "PifaceSwitch",
          "output": 0,
          "name": "My Reverse Switch",
          "reverse": true
        }   
    ]

Timed Switches

You may also want to create a timed switch that turns itself off after being on for a given time (for example, five seconds). This can be done by passing the 'time' argument in your config.json:

    "accessories": [
        {
          "accessory": "PifaceSwitch",
          "output": 0,
          "name": "My Timed Switch",
          "time": 5000
        }   
    ]

Resettable Timed Switches

You may also want to create a timed switch that is reset each time it is activated. This way, the original timer is reset instead of creating a new timer. This can be done by passing the 'resettable' argument in your config.json:

    "accessories": [
        {
          "accessory": "PifaceSwitch",
          "output": 0,
          "name": "My Stateful Switch",
          "time": 5000,
          "resettable": true
        }   
    ]
