Setting up Home Assistant so I can get home assisted
And finally came the day that I bought my first IoT gadget. It is a Broadlink RM4C Mini that I’m using to power on and off my old non-smart stuff. I’m already using alexa to control it, but not only it is limited to my smartphone as I don’t have full control over it. So on this post I’m going to write what I did to set it up on a LXD + Docker setup.
Some Exports
Some variables in case I return here some day:
export CONTAINER='example'
export IMAGE=ubuntu:20.04
export HOST_ARCH=$(dpkg --print-architecture)
export HOME_ASSISTANT_EXTERNAL_PORT=8123
export MY_TIME_ZONE=America/Fortaleza
Creating the container
Launch the container:
lxc launch $IMAGE $CONTAINER
If desired, edit the container description:
lxc config edit $CONTAINER
Upgrade all packages:
lxc exec $CONTAINER -- apt update
lxc exec $CONTAINER -- apt upgrade -y
Installing Docker
To install docker we must enable nesting, do this by running:
lxc stop $CONTAINER
lxc config set $CONTAINER security.nesting true
lxc start $CONTAINER
Install dependencies:
lxc exec $CONTAINER -- apt install -y ca-certificates curl gnupg lsb-release
Get docker’s GPG key:
lxc exec $CONTAINER -- bash -c "curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg"
Set up the repository:
export CONTAINER_RELEASE=$(lxc exec $CONTAINER -- lsb_release -cs)
lxc exec $CONTAINER -- bash -c "echo 'deb [arch=$HOST_ARCH signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $CONTAINER_RELEASE stable' | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null"
Update and install docker:
lxc exec $CONTAINER -- bash -c "apt update && apt install docker-ce docker-ce-cli containerd.io -y"
Installing home assistant
Create a folder where your configuration will be stored:
lxc exec $CONTAINER -- mkdir -p /docker_binds/homeassistant/config
Now start the Docker container:
lxc exec $CONTAINER -- docker run -d --name homeassistant --restart=unless-stopped -e TZ=$MY_TIME_ZONE -v /docker_binds/homeassistant/config:/config -p $HOME_ASSISTANT_EXTERNAL_PORT:8123 ghcr.io/home-assistant/home-assistant:stable
Expose the container port:
lxc config device add $CONTAINER homeassistant8123 proxy listen=tcp:0.0.0.0:$HOME_ASSISTANT_EXTERNAL_PORT connect=tcp:172.17.0.1:$HOME_ASSISTANT_EXTERNAL_PORT
This should do it. The rest is all about going to the web interface and set up Home Assistant graphically. You may refer to the official guide to see what to do next.
We’re done!
