# Chimera Doorlock

## Overview

-   Cards are synced with Cobot
-   Cards are stored in `cards.json` in the root of the project (should be `~/doorlock/cards.json` on the RaspberryPi)
-   Logs are stored in `logs.json` in the root of the project (should be `~/doorlock/logs.json` on the RaspberryPi)

## TODO

-   [ ] Update list of cards every few minutes
-   [ ] Push up logs/checkins to management app
-   [ ] Get working with Nexedus
-   [ ] Handle error message

## Configuring Raspberry Pi

On the RPI:

```bash
# Change to "sudo" user
sudo su

# Install nvm
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

# Install forever
npm i -g forever

# Clone the project and install dependencies
cd ~
git clone https://github.com/chimera/doorlock.git
cd doorlock
nvm install
nvm use
npm install

# Setup environment variables
cp .env.example .env
vi .env
# Add missing environment variables

# Start app
forever start src/server.js
```

Follow the [install from source guide for node-hid](https://github.com/node-hid/node-hid#compiling-from-source) becuase there is no pre-built binary for RaspberryPi

```
npm install -g node-gyp
apt install build-essential git libudev-dev gcc-4.8 g++-4.8 libusb-1.0-0 libusb-1.0-0-dev
export CXX=g++-4.8
npm install node-hid --build-from-source
```

You should now be able to view the app at http://localhost:3000

# Autostart

On a RasPi, copy the contents of the autostart file into: `~/.config/lxsession/LXDE-pi/autostart`

Optionally, to help users with debugging, run `ln -s /home/pi/doorlock/start.sh ~/Desktop/start-doorlock.sh` to give them a link on the desktop.

Or generally, find some way to run `./start.sh` in this folder
