How it works

Configure dasher-hue via config/config.json. You have to setup your Philips Hue (IP and username) and all the Amazon Dash Buttons you have.

Configuration

You define your buttons via the config/config.json file. You attach each button to a specific group or a specific light, what you prefer.

Here's an example.

{
  "philips_hue": {
    "ipaddress": "192.168.0.10",
    "username": "your-philips-hue-username-key"
  },
  "buttons":[
  {
    "name": "Amazon Dash Fiesta Living Room",
    "address": "50:50:50:50:50:51",
    "group": "1"
  },
  {
    "name": "Amazon Dash Rodial Bedroom",
    "address": "50:50:50:50:50:52",
    "group": "2"
  },
  {
    "name": "Amazon Dash ON Corridor",
    "address": "50:50:50:50:50:53",
    "light": "6"
  }
]}

Buttons take 4 options.

• name - Give the button action a name, just for informative purposes.
• address - The MAC address of the button.
• group - The number or the group you want to toggle. When using this, you don't use light.
• light - The number or the light you want to toggle. When using this, you don't use group.

Amazon Dash Button tips.

• Use DHCP Reservation on your Amazon Dash Button to lower the latency from ~5s to ~1s.
• Dash buttons cannot be used for another ~10 seconds after they've been pressed.

[Unit]
Description=dasher-hue

[Service]
ExecStart=/usr/local/bin/node /home/pi/dasher-hue/app.js
Restart=always
 # Restart service after 10 seconds if node service crashes
 RestartSec=10
 # Output to syslog
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=dasher-hue
Environment=NODE_ENV=production PORT=1337

WantedBy=multi-user.target

In /etc/systemd/system/dasher-hue.service And then use

sudo systemctl enable dasher-hue.service
sudo systemctl start dasher-hue.service

Locate Philips Hue Bridge automatically, rather than using an IP. Check: nupnpSearch(), locateBridges(), upnpSearch or searchForBridges()
