trådfri-flux

Make your IKEA Trådfri bulbs change temperature like f.lux.  

Installation

1. Obtain the security key (on the bottom of the gateway) and IP address of your Trådfri gateway (use your router's control panel).
2. Obtain your longitude and latitude (used for sunrise/sunset times). NASA has a tool for this.
3. Clone tradfri-flux git clone https://github.com/overwatchcorp/tradfri-flux.git
4. Install npm dependencies cd tradfri-flux && npm install
5. Run node bin/setup.js --host 127.0.0.1 --key a1b2c3d4e5f6g7h8i9j0 --lat 12.345 --long 3.141 to prepare the .env file, where hostname is the IP address of the gateway, and key is the security key found on the bottom of the gateway.
   • If you have a negative longitude or latitude, enclose the value in quotes and add a space before the negative sign so it doesn't interpret it as another argument: --long " -122.670"
6. Run npm start to start trådfri-flux

Running on a Raspberry Pi

If you have a Raspberry Pi, setting up trådfri-flux is a cinch and can run on startup.

1. Perform the installation
2. In tradfri-flux's directory, run sudo cp .env /.env to copy the .env var to your root folder
3. If tradfri-flux is located in /home/pi/tradfri-flux, run echo 'node /home/pi/tradfri-flux/index.js &' >> /etc/rc.local to add trådfri-flux to startup.
4. Reboot your pi with sudo reboot
