Jarvis is the VM running Home Assistant (HASS ) on Coherence and is able to automate tasks in the space

Web interface

Known issues

VM access

If you want access to the VM itself, for instance with SSH, use following creds:

  • User: nurds
  • Pass: the long one :)

root access

To gain root access to the jarvis vm, you need to attach a blockdevice to the VM with a single ext4 or vfat partition on there with the case-sensitive label "CONFIG". On this filesystem, place a file called "authorized_keys". Next, run "ha os import" from within the walled-garden shell. This will start sshd on port 22222, allowing you access as root to the VM. To disable this access, detach the blockdevice from the system. See the following procedure for more details: https://developers.home-assistant.io/docs/operating-system/debugging/

Starting HASS

It starts automatically with Erratic

iptables port forward: iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8123

Current Automations

  • Stop music on mpd when the space is closed
  • Start music on mpd when the space opens.
  • Power down EPC/APC and Sonoff when space is closed.
  • Power up Sonoff when space is open.

Custom stuff

Voice Assistant

OpenTherm Gateway

OpenTherm gateway has been put between the heater and the thermostat, see OpenTherm_Gateway

EPC (PDU)

Now replaced with epcMqttBridge by user:melan running on docker.vm.nurd.space. For source see https://github.com/NURDspace/epcMqttBridge

Notifications

LEDtickers

You can use services notify.ledticker_zaal1, notify.ledticker_bar and notify.ledticker_rookhok to send stuff to individual LEDtickers, or notify.all_ledtickers to send to all. The custom component for this can be found in /usr/share/hassio/homeassistant/custom_components/ledticker. New LEDtickers can be set up in /usr/share/hassio/homeassistant/configuration.yaml.

Todo:

  • Possibility to use host names instead of IPs

IRC bot notifications

Spams stuff using service notify.nurdbot @ Nurdbot using /usr/share/hassio/homeassistant/jsb/jsb-udpsend.

Does this work for GHBot????

Device tracker

We get MAC addresses that are connected to the Wifi from the Aruba AP. We do not track devices by default.

Why would you want to be tracked?

We can do reporting of tracked devices and whether they are 'home' or 'not_home'. One example that we have is !who on Nurdbot. We might also do personalized automations at some point.

Enable tracking for your wifi MAC address

If you want your wifidevice to be tracked, you need to search for your wifi MAC address in known_devices.yaml and add some details:

  • Open the file editor http://10.208.1.49/core_configurator
  • top left 'folder icon' , click it, search known_devices.yaml in the list, click it
  • ctrl-f for your mac address here (DO NOT ADD ENTRIES!!!)
  • Set track to true
  • Set name to something recognizable
  • Reload known_devices (Developer Tools -> YAML -> Restart)
  • Configure a person in http://10.208.1.49/config/person with the tracked device(s)

Changelog

  • Added the EPC PDU's to HASS
  • Added the space state
  • Added power usage
  • Added Axis camera
  • Added grote zaal rechts (TL)
  • Added Webcam connected to SlabPi
  • Moved to hass.io
  • Moved SonOff Basic to ESPHome and MQTT discovery
  • Added octoprint
  • Enabled device tracking through Aruba AP

Installation

We want to be able to easily update home assistant. One way to achieve this is to use Hass.io which in turn uses docker. On our proxmox environment it is not easy to run docker in a proxmox container, so we set up a proper VM for this.

Docker installation

Home assistant config location: /usr/share/hassio/homeassistant# Enabled docker repo and installed it (https://docs.docker.com/install/linux/docker-ce/ubuntu/). User nurds is in the docker group so it can do docker things without sudo.

Installed HASS.IO x86 https://www.home-assistant.io/blog/2017/11/29/hassio-virtual-machine/ Using the install script https://raw.githubusercontent.com/home-assistant/hassio-build/master/install/hassio_install

Logging MQTT addon turned off

Because mosquitto was filling the disks with logs a .conf file was put in /usr/share/hassio/share/mosquitto with following contents: 

log_dest none

After a restart of the addon, logging only shows startup until the added config file is read.

To Do

Radiator automation integration.
