Understanding the Raspberry PI 3 model B

The Raspberry Pi 3 is the third-generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016.

Specification:

  • Quad Core 1.2GHz Broadcom BCM2837 64bit CPU
  • 1GB RAM
  • BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board
  • 40-pin extended GPIO
  • 4 USB 2 ports
  • 4 Pole stereo output and composite video port
  • Full size HDMI
  • CSI camera port for connecting a Raspberry Pi camera
  • DSI display port for connecting a Raspberry Pi touchscreen display
  • Micro SD port for loading your operating system and storing data
  • Upgraded switched Micro USB power source up to 2.5A

Wiring

Step by Step instruction

We recommend using a high-performance SD card for increased stability as well as plugging your device into an external display to see the default application booting up.

We assume that you have Windows 10 installed on your PC and empty micro SD card 32 GB with SD card adapter.

1. Do wiring

2. Installing Hass.io

It was explained in Raspberry basics: Project 29a Raspberry PI 3 model B board - Home assistant for beginners

3. Adding integration Raspberry Pi GPIO switch

  1. To add integration to the configuration.yaml file go here and search for the Raspberry Pi GPIO switch.
  2. Just type Rapsberry Pi GPIO.
  3. Click on Raspberry Pi GPIO switch.
  4. Copy the entry given to your configuration.yaml file.
    # Example configuration.yaml entry
    switch:
      - platform: rpi_gpio
        ports:
          11: Lamp Bedroom
          12: Lamp Kitchen
    Copy this entry to your configuration.yaml file. In this entry we are adding two buttons that will control the Raspberry Pi GPIOs 11 and 12. We are calling them Green LED and Red LED. You can call them in different way and select other GPIOs too.
  5. If you have Configurator installed in Home Assistant skip installation notes. Go to Hass.io -> ADD-ON STORE  and select Configurator.
  6. Click on Install.
  7. Click on Start.
  8. Click on Open Web GUI.
  9. The configurator GUI opens. Go to Browse FileSystem.
  10. Go to config folder and find the configuration.yaml file.
  11. Save your configuration.yaml file.
  12. In the Home Assistant User Interface, go to Configuration->General and click the CHECK CONFIG button. This will check the syntax of the configuration.yaml file. When, it’s done, you get a Valid! message if everything is good with the syntax.
  13. Go to Server Management field (Configuration->General) and click on RESTART.
  14. Wait for the system to restart. 
  15. Go to Overview.
  16. Click on dots in top right corner. Select Configure UI.
  17. Click on plus in orange circle to ADD CARD.
  18. Click on ENTITIES.
  19. Type the title, make sure that Show header toggle? deselected, select Entity from dropdown menu - Green LED and Red LED. Click on SAVE.
  20. If you want to EDIT the card click on EDIT. If you want to go back to normal mode click on X.
  21. You should see two new buttons on the interface called Green LED and Red LED. Click on those buttons to turn the LEDs on and off.

Summary

We have learnt how to use Home Assistant with Raspberry Pi to control LEDs.
