HomeAssistant on Raspberry Pi

Installation (using pyenv)

Step1. Create a pyenv

First, we need to make sure python3 is installed. It’s recommended to set the pip registery to a domestic source.

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

Then, create a python3 virtual environment, or pyenv, at /opt/homeassistant

sudo mkdir -p /opt/homeassistant
sudo chown pi:pi /opt/homeassistant
cd /opt/homeassistant/
python3 -m venv .       # create venv (may take some time)

Step2. Enter pyenv and install homeassistant

We can enter into the venv by

source ./bin/activate

If you use ‘oh-my-zsh’, you can see a prefix named (homeassistant) in the interactive shell.

Then, inside the venv, execute

cd /opt/homeassistant/
pip3 install homeassistant
source /opt/homeassistant/bin/activate

The above may take some time, depending on your network condition.

After that, execute hass to start homeassistant service. It may take tremendous time at first executation. On raspi 3B, it takes about 20 to 30 minutes.

hass

You can visit homeassistant.local or <IP>:8123 (replace <IP> with your raspberry pi’s ip addr), and wait until the homeassistant welcome page appears.

Step3. Autostart

sudo vim /etc/systemd/system/homeassistant.service

Inside it, enter the following:

[Unit]
Description=Home Assistant
After=network-online.target

[Service]
Type=simple
User=pi
ExecStart=/opt/homeassistant/bin/hass -c "/home/pi/.homeassistant"

[Install]
WantedBy=multi-user.target

Save and exit, and then

sudo systemctl enable homeassistant
sudo systemctl start homeassistant

Install HACS

Step1. Download hacs plugin from github

The github address is https://github.com/hacs/integration/releases/tag/1.24.5

Make two folders custom_components and www inside the homeassistant’s root folder

cd ~/.homeassistant
mkdir custom_components
mkdir www
cd custom_components
mkdir hacs

And extract the hacs you downloaded to the custom_components/hacs folder.

Restart the homeassistant service, and you should see ‘HACS’ in the left sidebar.

You may need to authorize github for the first time you launch HACS.
