Show HN: Home Memory – A local DB of my house, down to cables and pipes

I've been documenting my house in software for years: outlets, conduits, circuits, pipe runs, appliances, vehicles. Having that data came in handy more often than I expected. But adding data was always the bottleneck. Opening the app, navigating to the right room, picking categories, filling in fields.

So I built an MCP server for that database. Now Claude, Codex, and other MCP-compatible clients can read and write the home data directly. Tell it about a heat pump in one sentence, or snap a photo of the nameplate, and it figures out the category and location. Later you can ask whether it's worth repairing given its age.

It also tracks physical connections between elements: cables, pipes, ducts, and where they run. The database is a single local file on your machine.

This would actually be the best to be running inside Home Assistant.

Interesting. I use HA myself (though not the AI/LLM side yet). I think it's a different layer: Home Memory is the physical reality of the whole house, not just what's wired and smart. How do you picture "running inside"? Chat from the HA UI, or just running on the same hardware? I haven't dug into the feasibility yet. The part I'm fairly sure about: this only shines with a model that reliably uses tools. 23 MCP tools is a lot for a small local model, Claude or GPT tier handles it fine. What conversation agent are you running in HA?
