Our first-hand build of a bilingual Home Assistant local voice assistant: what runs on the box, what we sent to the cloud, what broke, what it costs, and why microphones are the real obstacle.
Case study
Zigbee vs Thread vs Wi-Fi: Picking a Reliable Smart-Home Network
Lessons from a one-week Home Assistant build: why we put 22 of 24 lights on Zigbee, kept Wi-Fi for media and metering, and deliberately parked Thread until the host could support it properly.
Blue Iris vs Frigate: Why We Moved Our CCTV to Docker
We replaced Blue Iris with Frigate in Docker so our CCTV could run alongside Home Assistant, detect objects locally and live in Git, and the real cost turned out to be memory rather than money.
Home Assistant Local Voice Assistant: Bilingual for $2 a Month
How we built a mostly local English and Polish voice assistant on Home Assistant with Whisper, Piper and a small hosted LLM, what broke along the way, and why it costs about $2 a month.
Banksteer: A Private Finance App on Free Irish Bank APIs
How we replaced a household finance spreadsheet with Banksteer, a private app that reads AIB, Bank of Ireland and Revolut through free open-banking APIs, clears bills by itself and forecasts the months ahead. Built with Claude Code, kept at home, reachable only over Tailscale.
My House Has Opinions: Our Home Assistant Automations
A funny but technically honest tour of the Home Assistant automations in our smart home: motion lights, Adaptive Lighting, cubes, heating, TV manners, energy costs, AI helpers, and the automations that went spectacularly wrong. Written by Claude Code, tested by a human.
Inside the D3X Home Lab: Proxmox, DGX Spark and AI Agents
How a small Irish AI studio moved its lab off one overloaded Mac onto a Proxmox cluster, beside a DGX Spark, a 56 TB NAS and a Home Assistant house, with Claude Code agents planning and running it and a human approving every step that mattered.
Home Assistant with Claude Code: A Full Smart Home in a Week
How a Claude Code agent and one human built a full Home Assistant smart home in about a week: Zigbee2MQTT, Z-Wave, Thread and Matter, Frigate with local AI, bilingual voice, layered backups and a weekly AI health report, with what broke and what we learned.
