home assistant

home assistant runs everything in the house that has a radio or an app: lights, locks, leak sensors, the hvac, cameras, media, and the voice assistant. this section records what is installed and how it is configured, so i can rebuild it. it is an inventory, not a guide.

install Home Assistant OS 18.3, the ova image, as a VM on the proxmox cluster (how it moved there)
core 2026.10, on the beta update channel
disk 125 GB, about 55 GB used. the recorder database is most of it
radios z-wave, zigbee and thread live on the pi, not on the VM. thread has two border routers, see thread

pages

  • configuration: configuration.yaml, the yaml i wrote by hand, and the blueprints
  • integrations: every integration, and the custom ones
  • add-ons: what runs beside core
  • frontend: dashboards and the custom cards
  • esphome: the devices i build myself

how it fits together

  • almost everything is configured in the ui. yaml is kept for the few things the ui cannot do, or could not when i set them up
  • secrets live in secrets.yaml and are only ever referenced with !secret. nothing on these pages is copied from it
  • devices that need a server of their own run it elsewhere and home assistant talks to it: the carrier thermostat goes through infinitude, cameras through frigate, mqtt through mosquitto
  • i reach the config with the Advanced SSH and Studio Code Server add-ons, and claude reaches it through the Home Assistant MCP Server add-on
