===== Docker based Home Assistant and CCU on Raspbian =====
  
//[[micha@dipper.info|Michael Dipper]] 03.05.2020//

While setting up my smarthome solution the intention was to run all components on a single Raspberry Pi 3B+. Various componente had to be integrated:

=== Hardware ===

  * Raspberry PI 3B+
  * ELV "Charly" Case with RPI-RF-MOD
  * External antenna
  * SML Smart Meter adapter
  * Various (wireless) Homematic IP sensors and actors

=== Software ===

  * Home Assistant Supervised
  * Homematic CCU3
 
To get a flexible and modularized system I decided to have all components in docker containers. Therefore solutions like Raspberymatic are no option since they use a different container/virtualization technique.

The following script describes how to setup the environment.

==== Prepare ====

  * Flash Debian Buster Lite to SDcard
  * Enable "ssh" on SDcard
  * Boot Raspi and SSH to the system
  * Start raspi-config and set timezone and WiFi zone

Initial system update

  apt update
  apt upgrade

Adjust hostname in the following files:

  /etc/hosts
  /etc/hostname  

  reboot
  
==== Install Home Assistant ====

These steps are taken from the official Home Assistant documentation:

  apt-get install -y software-properties-common apparmor-utils apt-transport-https avahi-daemon ca-certificates curl dbus jq network-manager socat
  systemctl disable ModemManager
  systemctl stop ModemManager

  curl -fsSL https://get.docker.com | sh
  curl -sL "https://raw.githubusercontent.com/home-assistant/supervised-installer/master/installer.sh" | bash -s -- -m raspberrypi3

Wait for 10-20 minutes ...

Tip: The deploy.sh script will try to install the pivccu packages for you. If it does not work please follow the instructions to install pivccu-modules-dkms, pivccu-devicetree-armbian (if you are on Armbian) and pivccu-modules-raspberrypi (if you use a Raspberry with Raspbian). 

==== Install CCU ====

Furtunately there is a docker image for CCU available:

  cd ~
  apt-get install git  
  git clone https://github.com/angelnu/docker-ccu
  cd docker-ccu

  ./deploy.sh

==== Verify ====

Check if all containers are up and running:

  root@charly:/home/pi# docker ps
  CONTAINER ID        IMAGE                                              COMMAND                  CREATED             STATUS
