HomeLab & automation

Home Assistant, Docker services, and reliable home automation.

  • Home Assistant
  • Docker
  • YAML automations
  • Network segmentation

Overview

A personal platform for lighting, presence, alerts, and auxiliary services. The goal is reliability first: automations should fail safe and be easy to reason about months later.

Problem

Consumer IoT is fragmented. Without discipline, you end up with flaky triggers, opaque integrations, and a network that is hard to secure or reproduce.

Solution

Standardize on Home Assistant as the orchestration layer, run adjacent services in Docker with documented compose files, and keep automations small, named, and version-controlled where practical.

Architecture

VLANs or firewall rules where hardware allows; local DNS for stable internal names; backups for HA configuration; containers for databases, helpers, and experiments isolated from the supervisor.

Key decisions

Prefer local control over cloud dependence; avoid exotic add-ons on critical paths; invest once in observability (logs, notifications) to shorten incident time.

Challenges

Vendor quirks, hardware limits on ARM boards, and resisting the urge to over-automate edge cases that confuse household members.

Outcome

A maintainable home stack that mirrors how I think about production systems: clear boundaries, reproducible config, and operational habits that scale beyond a single app.
