The full story

With nothing available for Home Assistant, the poster mapped out the API for Delta VoiceIQ V2 smart faucets and built a complete integration "using Claude and a countless number of hours". It gives on/off control, metered dispensing, water usage tracking and an animated card.

Along the way he found Delta runs two separate auth systems, and the VoiceIQ one issues roughly 60-day tokens with no refresh token, so he built a browser-based page to handle token refresh.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
