Internet-enabled children's nightlight

Powered by Node.JS, Philips Hue.

Why Does This Exist?

I wanted my kids to have a nightlight in their room that:

  • Had programmable color
  • Had an adjustable timer (turns off X minutes after being turned on)
  • Had an interface to show history of button pushes (so I can see when they were awake)
  • Schedule the light to change color on a schedule (so at 7am it turns to blue to indicate "Ok, it's morning time!")

What Does This Do?

There is a Node.js web server that runs on the network, connects to the Philips Hue bridge, and listens on the network for some button to get pushed.

Each button gets associated with a light on the network. If the button is pushed and the light is off - the light is turned on (and a timer is started to automatically turn the light off after X minutes). If the button is pushed and the light is on - the light is turned off.

There is also a web application that sets the default color and colors during specific time periods. The web interface - in addition to showing times of button pushes - permits turning the light on with & without the timer, and turning the light off.


Getting The App Running

For the most part, it is a straight-forward Node.js application. After downloading this repo and extracting it to a directory of your choice, run:

  • npm install
  • npm run setup
  • sudo npm start

You can now access http://localhost:3000/ and view the complete interface. (On my home network, I put this behind nginx and set the in-house DNS to know it as "nightlight". So now babysitters and family just go to http://nightlight/ to use it.)

Keeping The App Running

You'll find plenty of other great tutorials on the web about running a Node.js app as a daemon, but here are a couple:


Desktop interface for monitor and control
Mobile interface for monitor and control
mobile view


You can’t perform that action at this time.
