homebridge-gpio-electromagnetic-lock v1.1.1

Homebridge GPIO Electromagnetic Lock

Homebridge plugin to control electromagnetic lock via Raspberry Pi GPIO pins.

Motivation

I haven't found similar script working with Raspberry Pi GPIO.

Installation

1. install homebridge npm install -g homebridge
2. install this plugin npm install -g homebridge-gpio-electromagnetic-lock
3. update your ~/.homebridge/config.json file (use sample-config.json as a reference)

Configuration

Sample accessory:

"accessories": [
  {
    "accessory": "ElectromagneticLock",
    "name": "Lock",
    "lockPin": 5,
    "doorPin": 16,
    "activeLow": false,
    "reedSwitchActiveLow": false,
    "unlockingDuration": 2,
    "lockWithMemory": true
  }
]

Fields:

• accessory must always be ElectromagneticLock
• name accessory name, e.g. Lock
• lockPin pin for unlocking lock (use gpio numbering, not physical)
• doorPin optional door contact sensor, ignored when lockWithMemory is set to false
• activeLow optional, default: true true: relay activated by low state (0), false: relay activated by high state (1), affects lockPin
• reedSwitchActiveLow optional, default: true true: reed switch activated by low state (0), false: reed switch activated by high state (1), affects doorPin
• unlockingDuration optional, default: 2 how long lockPin should be active (seconds)
• lockWithMemory optional, default: true true: electromagnetic lock that stays unlocked until full door cycle, false: stays unlocked only for unlockingDuration seconds

Troubleshooting

• check platform: Homebridge
• check plugin dependency: rpio
• or create issue
