Squid Games with Home Assistant (Green Light, Red Light)

Today I was thinking about a cool project to do with my smart home running home assistant, and I was thinking to recreate a game from the popular Netflix show Squid Games, in particular the green light red-light.

To do this project you will need, a coloured led light-strip or bulb, a few vibration sensors, a button and a google mini.

Kit Required for this project

1. Led Light Bulbs (coloured) or some led light-strips
2. Zigbee Button (I’m using an Ikea shortcut button)
3. Google mini
4. Vibration sensors (I’m using an Aqara Vibration sensor)
5. Smart home platform.

My smart home platform of choice is home assistant, I’m assuming you already have this up and running, if you don’t follow my free course: https://courses.leonardosmarthomemakers.com/courses/home-assistant-foundations

Automations

I’m using 2 automations, the first turns on our lights either green or red depending on if you do a single tap or long tap. Feel free to configure this in your own way depending on which button you are using. The great thing about home assistant is that you can use so many devices!

Turning Lights ON (Green & Red)

My Ikea shortcut button works only thanks to a blueprint which you can find here. After you have installed it feel free to copy and paste the code below in your automation.yaml

Now if you are not using an Ikea button you can skip the blueprint step.

Example with Philips Hue button

Replace device ID with your own, you can find that by trying to create an automation with the UI first (devices). Then looking at the code snipped generated in automations.yaml

Eliminating Players

Now in the game players are eliminated when they move and the light is red

Each player will be assigned a vibration sensor, create multiple automations for each player.

Replace the vibration_player_1 with your own entity id. Same for the light and the media player.
