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

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 prober 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

Actions done

• Add all mqtt sensors
• Add all other config that works out of the box
• Migrate APC power bar scripts
  • on/off
  • Amp meter
• Migrate noname power bar scripts
• Migrate nurdbot notifier
• Migrate all automations

Migration

• Move the IP
• Change the SNMP community for the APC to the right one for the new ip
