Jarvis is the VM running Home Assistant (HASS) and is able to automate tasks in the space See http://10.208.11.32/ or http://10.208.11.32:8123 when port 80 is not working. Port 80 should work because of a port forward started from /etc/rc.local.

Starting HASS

/etc/init.d/homeassistant install
/etc/init.d/homeassistant start

It should do this on boot through /etc/rc.local.

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

OpenTherm Gateway

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

Flukso

Runs stuff for power meter, see Flukso.

New jarvis

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

The idea is to get the config from the old jarvis working and at some point have the new one take the IP address of the old one. For now the new one is configged with DHCP.

• Temp IP: 10.208.42.142
• User: nurds
• Pass: the long one :)

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

Actions done

• Add all mqtt sensors
• Add all other config that works out of the box

Actions open

• Migrate nurdbot notifier
• Migrate APC power bar scripts
  • on/off
  • Amp meter
• Migrate noname power bar scripts
• Migrate all automations

Web interface

• user: nurds
• pass: same as wifi ask in the space

To Do

Radiator automation integration.
