Ansible roles for my Raspberry Pi for home automation

ansible-raspi

The setup of my Raspberry Pi used for home-automation:

• Raspbian Lite (headless, no UI)
• docker
• piVCCU3 (Homematic IP)
• ioBroker
• MQTT for e.g. Tasmota plugs
• InfluxDB for logging from ioBroker
• Grafana for visualizations

Prepare the SD card

Install Raspbian Lite

1. Download the image

   curl --location https://downloads.raspberrypi.org/raspbian_lite_latest --output raspbian.zip
   unzip raspbian.zip
   rm raspbian.zip

2. Prepare SD card for flashing

   Insert SD card and check its device name and potentially mounted partitions with lsblk -p. Unmount partitions that got mounted automatically by the OS.

   Linux:

   # Find device assigned to the SD card, e.g. /dev/sdc.
   lsblk -p
   # Unmount.
   umount /dev/<from above>

   macOS:

   # Look for something like /dev/disk2 (external, physical).
   diskutil list
   # Find mount point.
   mount | grep /dev/<from above>
   # Unmount.
   diskutil unmount /Volumes/<path>

3. Flash the SD card

   sudo dd if=*-raspbian-buster-lite.img of=/dev/<from above> bs=4M

4. Enable SSH

   SSH is the major way to connect to the Pi, but it is not enabled by default.

   # The mount point may be /media/$USER or /Volumes/boot depending on your OS.
   touch <boot volume mount point>/ssh

First boot

Unmount all drives.

umount /dev/<SD card>
umount /dev/<external disk> # Optional.

diskutil unmount /Volumes/<SD card>
diskutil unmount /Volumes/<external disk> # Optional.

Remove the SD card, plug it into the Raspberry Pi. Do not connect the external drive if you want to boot from it (see below). Boot the Pi with connected ethernet. Check its reachability with ping.

ping raspberrypi

ssh pi@raspberrypi

You may run raspi-config to e.g. set up a Wi-Fi connection or a different hostname.

Enable Ansible

$ ssh-copy-id pi@raspberrypi

$ ansible raspberries -a '/bin/echo It works' --become
raspberrypi | CHANGED | rc=0 >>
It works
