The full story

Wanting a cloud integration for his APsystems EZ1 balcony micro-inverter, the poster decompiled the official AP EasyPower Android app with jadx and reproduced its authentication scheme, then built a Home Assistant integration that reads power and energy from the cloud API.

Asked whether it was vibe coded, he says "Yes but not entirely", and that Claude Code helped him a lot with reverse engineering the app.

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). The Claude connector only receives the search words your Claude sends it.
