Home Lights

Control system for multi-vendor home lighting systems.

Currently supported vendors:

• Philips Hue
• LIFX
• RVL (My custom animation lighting system)

A Raspberry Pi makes an ideal system for running Home Lights, and all instructions below are written assuming a Raspberry Pi. Home lights will run just fine on other systems, but the instructions below may not work without modification.

Installation

sudo mkdir /app
# If you set up a custom username, replace pi:pi with name:name
sudo chown -R pi:pi /app
npm config set prefix /app
npm install -g home-lights
sudo ln -s /app/bin/home-lights /usr/bin/home-lights

Yeah, this is a lot. Super tl;dr, creating the symlink that npm does by default and building the SQLite binary required conflicting sets of permissions when trying to install to /usr/lib/node_modules and /usr/. This workaround avoids the conflict, which I developed after I managed to brick a Pi.

Once this is done, you can update Home Lights by running:

npm install -g home-lights

Setting up a WiFi AP on a Raspberry Pi:

Follow instructions here.

Note: there was an update to Raspbian that changed things a bit. You'll need to run these commands once you're done with everything from the above instructions:

sudo systemctl unmask hostapd
sudo systemctl enable hostapd
sudo systemctl start hostapd

Running on system startup

We'll use systemd to manage the process. Create a file at /etc/systemd/system/home-lights.service. Inside this file, add the following:

[Unit]
Requires=systemd-networkd.socket
After=systemd-networkd.socket

[Service]
ExecStartPre=/lib/systemd/systemd-networkd-wait-online --interface=wlan0
ExecStart=home-lights
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=home-lights
Environment=NODE_ENV=production
Environment=PORT=80
User=root
Group=root

[Install]
WantedBy=multi-user.target

If your server won't be listening on wlan0, change it to the appropriate interface.

Then, run these commands:

sudo systemctl enable systemd-networkd-wait-online.service
sudo systemctl enable home-lights

Next time your reboot your application, it should be running! You can check the status of your service by running systemctl status home-lights, check the console output of your service by running journalctl -u home-lights, and restart your service by running sudo systemctl restart home-lights.
