1.更换Python版本
由于在新版的homeassistant当中需要使用python3.5.3及以后的版本，但由于apt源中只包含3.5.2的版本，所以需要升级到python3.6。
具体更换方式：
sudo add-apt-repository ppa:jonathonf/python-3.6 sudo apt-get update sudo apt-get install python3.6 python3.6-venv python3.6-dev
具体可参考：https://github.com/home-assistant/home-assistant/issues/13089
安装Python3.6的pip【2】：
curl https://bootstrap.pypa.io/get-pip.py | sudo -H python3.6
具体可参考：https://github.com/home-assistant/home-assistant/issues/13089
关于更换到国内镜像：
pip install pip -U pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
具体可参考：https://mirror.tuna.tsinghua.edu.cn/help/pypi/
更换默认python版本：
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1 sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2 sudo update-alternatives --config python3

2.homeassistant的安装
具体的安装过程可参考：https://juejin.im/post/5a74a2515188257a814ce254
cd /home/pi/Desktop && python3 -m venv homeassistant cd homeassistant source bin/activate python3 -m pip install wheel python3 -m pip install homeassistant hass --open-ui
3.设置自启动
1.创建 home-assistant.service ,并放入以下内容 sudo vim /etc/systemd/system/home-assistant.service
[Unit] Description=Home Assistant After=network.target[Service] Type=simple User=pi Environment=PATH="$VIRTUAL_ENV/bin:$PATH" ExecStart=/home/pi/Desktop/homeassistant/bin/hass -c "/home/pi/.homeassistant"[Install] WantedBy=multi-user.target
2.更新系统设置
sudo systemctl --system daemon-reload 3.设置HomeAssistant开机启动
sudo systemctl enable home-assistant.service 4.启动
sudo systemctl start home-assistant.service
