I had come across Home Assistant a while back, and finally set it up this weekend. It was pretty quick and easy.

I ordered the Canakit Raspberrry Pi 4 8 GB Extreme Kit from Amazon. The full list of supported hardware can be found in the Home Assistant Installation instructions.

There are a couple of things to be done differently for a Pi 4:

  • I used the latest build Development 5, Release 1, specifically the 64-bit version (hassos_rpi4-64-5.1.img.gz)

  • As described in the instructions, I set up the WiFi using a blank USB stick (FAT 32 format, volume label CONFIG) with a file /network/my-network with the contents shown here: the example under “Wireless LAN WPA/PSK”. Only lines to change here are the ssid and psk settings for ure wireless LAN.

  • That was it. After rebooting you can access your Home Assistant at http://homeassistant.local:8123
