Assist your home automation

Home Assistant

Home Assistant is a home automation platform written in Python, with extensive support for 3rd-party home-automation platforms including Xaomi, Phillips Hue, and a bazillion others.

This recipie combines the extensibility of Home Assistant with the flexibility of InfluxDB (for time series data store) and Grafana (for beautiful visualisation of that data).

Preparation

Setup data locations

We'll need several directories to bind-mount into our container, so create them in /var/data/homeassistant:

mkdir /var/data/homeassistant
cd /var/data/homeassistant
mkdir -p {homeassistant,grafana,influxdb-backup}

Now create a directory for the influxdb realtime data:

mkdir /var/data/runtime/homeassistant/influxdb

Prepare environment

Create /var/data/config/homeassistant/grafana.env, and populate with the following - this is to enable grafana to work with oauth2_proxy without requiring an additional level of authentication:

GF_AUTH_BASIC_ENABLED=false

Setup Docker Swarm

Create a docker swarm config file in docker-compose syntax (v3), something like this:

Serving

Launch Home Assistant stack

Launch the Home Assistant stack by running docker stack deploy homeassistant -c <path -to-docker-compose.yml>

Log into your new instance at https://YOUR-FQDN, the password you created in configuration.yml as "frontend - api_key". Then setup a bunch of sensors, and log into https://grafana.YOUR FQDN and create some beautiful graphs :)
