Hi! 😊

Flashing led lights when you go Incognito Mode

Flashing led lights when you go Incognito Mode

Last week, I received  one of the wifi-controller for my Wifi bulb (milight) and a crazy thought came across my mind to make it flash whenever I go incognito Mode on my chrome browser on a LINUX machines.

To accomplish this crazy idea, I have used the following components:

  1. Wifi Bulb with its wifi-controller (Milight)
  2. RaspberyPi running a node-red server
  3. Linux PC – running chrome browser and of course a script which was written in Bash

How it works?

  1. LinuxPc (running a bash script, when an incognito session is detected, it makes a curl towards the webservice of node-red)
  2. The node-red flow captures this data from the curl and then it sends a requests to the wifi-controller
  3. The wifi controller then sets the value that it has got from the node-red



1. Configuring the Wifi Bulb and the Wifi controller
The wifi bulb can be bought on Ebay along with the wifi-controller


  • Download a milight APP from Play-store (I’m currently using this app (Mi-Light) which is available on play store https://play.google.com/store/apps/details?id=mi_light.mi_light )
  • Once the wifi-controller is connected to a power socket, in order to setup the whole thing, you will have to connect to its wifi with your phone.
  • Once connected, you can specify the network SSID/username/passwd of your wifi router on the settings of the wifi-controller so that it can connect to your local network
  • Having done so, your wifi-controller should be able to connect to your network
  • Use the app on your phone, it will already detect the controller
  • Linking your wifi bulb with the controller
    • On the APP, choose a setup for your bulb (or follow the manually of the wifi controller)
    • Poweroff the wifibulb
    • Poweron your wifibulb
    • You got around 1-5seconds to press the linking button on the app so as the bulb will be able to communicate to the wifi controller
    • You should be able to change your bulb colour and have some fun with the different modes available on the App.

2. Installing Node-red On raspberry Pi,

This guide is enough to install the node-red http://nodered.org/docs/hardware/raspberrypi


3. Install a milight node on node-red

The instructions is clear to install the node http://flows.nodered.org/node/node-red-contrib-milight

npm install node-red-contrib-milight

4. Use the following codes on the node-red interface (http://IP:1880)

On for right-hand-side, import->clipboard and input this codes

How the flow looks like in Node-Red

5. Bash Scripts on a linux console

while ( true)
x=`ps -ef |grep chrom |grep "disable-databases"`
if [ ! -z "$x" ] ; then
echo "Incognito Mode On"
curl -XGET -m 1 2>/dev/null
echo "Normal Browsing"
curl -XGET -m 2> /dev/null

See the GIF The works in progress..

On your chrome, just switch to incognito mode and see this works πŸ˜€

You can tweek the codes, to do anything you want πŸ™‚

Node-red is really amazing for IOT projets πŸ˜‰
